sorry, what exact version(s) is the one(s) affected again?

(or SHAs, etc.)

(EDIT: 5.6.0 and 5.6.1 ?)

(EDIT 2: Ooof, looks like the nix unstable channel uses xz 5.6.1 at this time)

I use Nix to manage this stuff on Mac, not Homebrew...

[redxtech]

GitHub disabled the xz repo, making it a bit more difficult for nix to revert to an older version. They've made a fix, but it will take several more days for the build systems to finish rebuilding the ~220,000 packages that depend on the bootstrap utils.

Lol they shouldn't be relying on GitHub in the first place.

What should they be relying on instead? Maybe rsync everything to an FTP server? Or Torrents? From your other comments, you seem to think no one should ever use GitHub for anything.
