Tried it on Fedora 43 (6.19.11 x86_64) and it loaded all CPU cores, dumped 50K lines in the journal and failed to start.

Sorry, we have not tested on Fedora before release. Did not expect so much interest in the first hours after release...

I have now installed Fedora in a VM (ARM64 architecture, though) and it does load, but cannot identify processes. I'm investigating this now.

The other issue seems to be with eBPF compatibility. That's a moving target and I'll investigate next. But resources are limited, I'll need some time to dig into this.

There's some good feedback in the GitHub issue on the subject, seems to happen on slightly newer versions of the kernel than the one you've tested on and affects other distros like Arch as well. I'll keep an eye on the discussion and test again once updates are ready.

From the download page on the website:

"Note: Little Snitch version 1.0.0 does not currently work with the Btrfs file system! Btrfs is used by default on Fedora, so Little Snitch does not currently identify processes on Fedora. We are working on an 1.0.1 release to fix the issue as soon as possible!"

Someone already created an issue for it: https://github.com/obdev/littlesnitch-linux/issues/1

It crashed my Fedora 43 installation (maxed out CPU and RAM) right after installing from .rpm. After reboot it can't even load plasmashell. I'm typing this after booting into a Fedora 42 backup. 42!

I was looking for a comment like yours. Same issue, in my case only eating up half of my cores but with 100% utilization, webUI not working.

[tommodev]

Had the same issue on arch, though survived it OK (6.19.11-zen1-1-zen). Maybe it's a zen kernel thing, it only pegged 2-3 cores and the others were OK so could jump in and kill it.

Your average Linux experience.

And the second most upvoted comment is someone seriously asking if 2026 if the year of Linux desktop...

[Latty]

Yeah, because no third party program has ever crashed on any other OS.

Come on, this is an absurd comment. Linux has its issues, this is not a serious example of what is keeping normal people from using Linux as a desktop OS. Normal people are not installing the first release of a privacy networking tool that requires you to OK connections.
