    Debian will remove code that “calls home”
    or tries to update software in a way that
    bypasses the Debian packaging system.
Thank god. I'm so happy that such a distro exists.

Most good stuffed Distros do this. For example SUSE recently banned a package because of "calling home" e.g. did side-leading. https://security.opensuse.org/2025/05/07/deepin-desktop-remo...

Debian indeed does this. In release FF has disabled telemetry: https://wiki.debian.org/Firefox

Unfortunately that is not entirely true.

For example, when closing firefox on OpenSUSE Leap 15.6, "pingsender" is launched to collect telemetry:

It has been there for years. It is also on other distros.

Did someone report/open a issue about it? Maybe it's as simple as them not being aware of it.
I wouldn't think the Firefox license allows them to do that. I thought only binaries built by Mozilla could use the FF brand.
Indeed, Mozilla only recently allowed Debian to use the brand for their modified version: https://en.wikipedia.org/wiki/Debian%E2%80%93Mozilla_tradema...
Recently? It was almost a decade ago: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=815006
That’s the reason for a while we had IceWeasel
This is unfortunately not part of Debian Policy yet, and there are still lots of privacy issues of different severities in Debian.

https://wiki.debian.org/PrivacyIssues

I don't use Debian for servers nor personal computers anymore, but the fact that they themselves host a page explaining potential privacy issues with Debian makes me trust them a lot more, and feel safer recommending it to others when it fits.
Thats just a wiki page, written by myself and a bunch of other Debian members/contributors. Don't read too much into it :)
What are you using instead now? Nixos?
Yeah, NixOS for all servers (homelab + dedicated remote ones) and Arch on desktop.
Arch is a minefield on this regard tbh
Hey, I might be too late to the party, but I'd love to get some more info to your comment.

Imagine me: I'd consider myself a Linux noob, although I probably aren't anymore. I use Arch Linux for about 3 years now as my daily driver. I'm not young anymore - I didn't grew up with computers - I don't have it in my blood. I don't have formal education in anything computer and have never worked in the field. During Covid I learnt Linux from the Arch wiki. Now I'm using it. I configured some things and can control my computer through the command line.

Everytime I read comments like yours, I get the shivers. Did I miss something integral? What do I not know about? Especially network stuff is a blind spot for me. I didn't touch network stuff beyond the default wiki pages.

When I read comments like yours "Arch is a minefield" "With Arch it is so easy to shoot yourself in the foot", I never know what this could be specifically. How could this look like? Can you give me something more concrete? I'm really eager to know what everyone is talking about.

To be even more honest, it is what you make of it ¯\_(ツ)_/¯
Arch has been bliss for me. I'm heavy on Flatpaks and primarily use Arch as a base operating system with very minimal config changes.
This policy is missing from nixpkgs, although there is a similar policy for the build process for technical reasons.

So I can add spotify or signal-desktop to NixOS via nixpkgs, and they won’t succeed at updating themselves. But they might try, which would be a violation of Debian’s guidelines.

It’s a tough line — I like modern, commercial software that depends on some service architecture. And I can be sure it will be sort of broken in 10-15 years because the company went bust or changed the terms of using their service. So I appreciate the principles upheld by less easily excited people who care about the long term health of the package system.

In the process of trying to update, Spotify on NixOS will likely display some big error message about how it's unable to install updates, which results in a pretty bad user experience when everything is actually working as intended. It seems fair to patch software to remove such error messages.
To be fair, we (Nixpkgs maintainers) do remove or disable features that phone home sometimes even though it's not policy. That said, it would be nice if it was policy. Definitely was discussed before (most recently after the devbox thing I guess.)
Discord downloads stuff every single time I start it. So there is definitely not a policy to remove this behaviour.

And yes, good point, this was indeed discussed when devbox enabled AI training by default. It somehow seems like there is more than one category of phoning home at play here, since it is obviously tolerated in other cases.

What I mean is, it definitely isn't explicit policy to remove features that phone home; but, it is sometimes still done at the package maintainer's discretion. For things that are unfree all bets are off. (Removing or interfering with such code may be against the license.)
I'm glad that opensnitch is available in Debian trixie too, to mitigate the issues that Debian has not found yet.
Why can't I get GNOME stop calling home? (on a Debian installation) Each time I fire up my Debian VM with GNOME here on my OSX host system Little Snitch pops up because some weird connection to a GNOME web endpoint. One major pet peeve of mine.
You can ask the gnome team if they'd accept a patch. They might be of the idea that patching stuff out is bad.
Please send patches.
I was extremely disappointed to recently learn that visidata(1) phones home, and that this functionality has not been disabled in the Debian package, despite many people requesting its removal:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1001647

https://github.com/saulpw/visidata/discussions/940

The maintainer’s responses in that thread are really frustrating. They just keep describing the bug as though the package’s behavior is acceptable.

I wonder what debian’s process is for dealing with such maintainers.

I hope they make “no phone home” actual policy soon.

Infuriating. The developer is just making excuses and refusing to address the users' actual concern. And why are they phoning home in the first place? What is this critical use case that requires this intrusion?

    "This daily count of users is what keeps us working on the project, because otherwise we have feel like we are coding into a void."
So, they wrote code to phone home (by default) and then digging in and defending it... just for their feelings? You've got to be kidding me!
> So, they wrote code to phone home (by default) and then digging in and defending it... just for their feelings? You've got to be kidding me!

Is that better or worse than phoning home to serve ads?

Also, if feels misleading to me to call fetching a motd phoning home. You know Ubuntu does this too right? That feels more worthy of outrage than this.

If someone tells me, this software phones home, and it's not transmitting anything other than a ping; kinda feels like they're lying to me about what it's actually doing.

I'm not upset by the author wanting a bit of human connection to the people who enjoy his software. I empathize with the desire to see people enjoy the stuff I've made. Is it a privacy risk? Perhaps, but it's not even on the top 1k that I see daily. There's more important windmills to tilt at.

But... if you really just wanna be outraged; I recently wrote a DNS server that I use as the default for my home system. Currently It prints every request made, you might wanna try something like that. If you're that upset about this, you're gonna be blown away by what else is going on you didn't even know about.... and that's just dns queries, it's not even the telemetry getting sent!

It's not guaranteed that they manage to catch all the software that does this though :D
Any such leftover behavior is going to be a reportable and fixable bug then.
I'm not sure it's explicitly in the policy or if any team can decide what to do…
It isn't in policy yet no.

https://wiki.debian.org/PrivacyIssues

It's not guaranteed that policies enforce every possible case though.
> It's not guaranteed that they manage to catch all the software that does this though :D

It is really hard to run netstat. Or tcpdump. /s

This is one of my favorite things about Debian.
So they have their own Go fork?

Just one possible example, among many others that have telemetry code into them.

No they don't. The formulation in TFA is a bit too generic - Debian will usually not remove any code that "calls home". There are perfectly valid reasons for software to "phone home", and yes, that includes telemetry. In fact, Debian has its own "telemetry" system:

https://popcon.debian.org/

Telemetry is perfectly acceptable as long as it is opt-in and does not contain personal data, and both apply to Go's telemetry, so there's no need for a fork.

> Telemetry is perfectly acceptable as long as it is opt-in and does not contain personal data

Telemetry contains personal data by definition. It just varies how sensitive & how it's used. Also it's been shown repeatedly that 'anonymized' is shaky ground.

In that popcon example, I'd expect some Debian-run server to collect a minimum of data, aggregate, and Debian maintainers using it to decide where to focus effort w/ respect to integrating packages, keeping up with security updates, etc. Usually ok.

For commercial software, I'd expect telemetry to slurp whatever is legally allowed / stays under users' radar (take your pick ;), vendor keeping datapoints tied to unique IDs, and sell data on "groups of interest" to the highest bidder. Not ok.

Personal preference: eg. a crash report: "report" or "skip" (default = skip), with a checkbox for "don't ask again". That way it's no effort to provide vendor with helpful info, and just as easy to have it get out of users' way.

It's annoying the degree to which vendors keep ignoring the above (even for paying customers), given how simple it is.

> Telemetry contains personal data by definition

Why it has to include PII by definition? I'd say DNF Counting (https://github.com/fedora-infra/mirrors-countme) should be considered "telemetry", yet it doesn't seem to collect any personal data, at least by what I understand telemetry and personal data to mean.

I'm guessing that you'd either have to be able to argue that DNF Counting isn't telemetry, or that it contains PII, but I don't see how you could do either.

IPs are PII. You hit the server, and your anonymity is breached.
Yes, so the vendor must not store it. Something along those lines is usually said in the privacy policy. If you don't trust the vendor to do that, then do not opt-in to sending data, or even better, do not use the vendor's software at all.
The ongoing problem with popcon is that it's known not to be accurate, but since it's the data that's available, people make decisions based on it.

popcon is least likely to be turned on by:

- organizations with any kind of sensible privacy policy (which includes almost everyone running more than a handful of machines)

- individuals concerned about privacy

popcon is most likely to be turned on by Debian developers, and people new to Debian who have just installed it for the first time.

Yeah, isn't that a shame? Wouldn't it be nice if instead of catastrophizing that telemetry data is always only ever there to spy on us, that we might assume that there are actually trustworthy projects out there? Especially for FOSS projects, which can usually not afford extensive in-house user testing, telemetry provides extremely valuable data to see how their software is used and where it can be improved, especially in the UX department, where many FOSS is severely lacking. This thread here is a perfect example of this kind of black/white thinking that telemetry must be ripped out of software no matter what, usually based on some fundamental viewpoint that anonymity is impossible anyway, so why bother even trying. This is not helping. I usually turn on telemetry for FOSS that offers it, because I hope they will use this to actually improve it.
Turning it on and being unable to turn it off aren't the same.
> I usually turn on telemetry for FOSS that offers it, because I hope they will use this to actually improve it.

And if they, or someone else, use this for RCE ? Asking for a friend. /s

> Telemetry contains personal data by definition.

No. Please look up the definition of "telemetry" and "personal data". The latter always refers to an identifiable person.

Virtually all anonymization schemes are reversible, so “identifiable” isn’t carrying any weight in your definition.

“Person” isn’t either, unless the software knows for sure it’s not being uses by a person.

By your definition, all data is PII.
> Telemetry is perfectly acceptable as long as it is opt-in and does not contain personal data, and both apply to Go's telemetry, so there's no need for a fork.

This changed somewhat recently. Telemetry is enabled by default (I think as of Golang 1.23?)

I am only aware since I relatively recently ran into something similar to this on a fresh VM without internet egress: https://github.com/golang/go/issues/68976

https://github.com/golang/go/issues/68946

If golang doesn't fully address this I guess Debian really should at least change the default (of they haven't already).

It creates telemetry data, but actually transmitting it is opt-in.
Attempts to contact external telemetry servers under default configuration is the issue. That not all of the needlessly locally aggregated data would actually be transmitted is separate.
“Will remove” means that it’s one of the typical/accepted reasons why patches are applied by Debian maintainers, as in meaning 4 here [0], not that there is a guarantee of all telemetry being removed.

One of the many reasons I switched from Ubuntu to Debian 2 years ago. Another reason was snap.
Yup. Snap is emblematic of all the complexity Canonical bakes into Ubuntu.
That and the whole systemd stack. Canonical employees had enough votes to force upstream it into debian.

I switched to devuan. It’s great, but it sucks that the community split over something so needlessly destructive.

Between snap and having completely different network implementations between "desktop" and "server" versions really made me fall back down the learning curve of nix.

Especially since I was novice at best before the systemd thing, and my Ubuntu dive involved trying to navigate all 3 of these pretty drastic changes at once (oh yea and throw containers on top of that).

I went into it with the expectation that it was going to piss me off, and boy did it easily exceeded that threshold.

God, I wish someone would do this to discord already. I'm so sick of updating it through my package manager every other day only for discord to then download its own updates anyway.

Yes, I've disabled the update check. No, it doesn't solve the problem.

This is no longer true.

Most obvious example is Firefox. The Debian Project allows Firefox to update outside the packaging system, automatically, at the whim of Firefox.

And there's the inclusion of non-Free software in the base install, which is completely against the Debian Social Contract.

The Debian Project drastically changed when they decided to allow Ubuntu to dictate their release schedule.

What used to be a distro by sysadmins for sysadmins, and which prized stability over timeliness has been overtaken by Ubuntu and the Freedesktop.Org people. I've been running Debian since version 3, and I used to go _years_ between crashes. These days, the only way to avoid that is to 1) rip out all the Freedesktop.Org code (pulseaudio, udisks2, etc.), and 2) stick with Debian 9 or lower.

> Most obvious example is Firefox. The Debian Project allows Firefox to update outside the packaging system, automatically, at the whim of Firefox.

No, it's not. Stable ships ESR which has its update mechanism is disabled. Same for Testing/Unstable. It follows standard releases, but autoupdate is disabled.

Even Official Firefox Package for Debian from Mozilla has its auto-updates disabled and you get updates from the repository.

Only auto-updating version is the .tar.gz version which you extract to your home folder.

This is plain FUD.

Moreover:

Debian doesn't ship pulseaudio anymore. It's pipewire since forever. Many people didn't notice this, it was that smooth. Ubuntu's changes are not allowed to permeate without proper rigor (I follow debian-devel), and it's still released when it's ready. Ubuntu follows Debian Unstable, and Unstable suite is a rolling release, and they can snapshot it and start working on it whenever they want.

I'm using Debian since version 3 too, and I still reboot or tend my system only at kernel changes. It's way snappier w.r.t. Ubuntu with the same configuration for the same tasks, and is the Debian we all know and like (maybe sans systemd. I'll not open that can of worms).

pulseaudio is default for atleast kde desktop in current debian stable. Trixie might change that, but its not official release yet
Firefox only updates on its own if installed outside of the package manager. This applies to Debian and its forks. If I click on Help -> About it says, "Updates disabled by your organization". I personally would like to see distributions suggest installing Betterfox [1] or Arkenfox [2] to tighten up Firefox a bit.

>Most obvious example is Firefox. The Debian Project allows Firefox to update outside the packaging system, automatically, at the whim of Firefox.

It seems likely that you personally chose to install a flatpak or tar.gz version probably because you are running an older no longer supported version of Debian.

>These days, the only way to avoid that (crashes) is...

Running older unsupported versions with known never to be fixed security holes isn't good advice nor is ripping out the plumbing. Its almost never a great idea to start ripping out the floorboards to get at the pipes.

Pipewire seems pretty stable and if you really desire something more minimal it's better to start with something minimal than stripping something down.

Void is nice on this front for instance.

Long time Debian fan, current Devuan user. I'm sure it still has it's problems, but it feels nice and stable, especially on older hardware that is struggling with the times. (Thinkpad R61i w/core2duo T8100 swapped in and middleton bios)
