Arch Linux Megathread

Welcome

This is Millennium's Arch Linux mega thread. It holds all related discussions and issues. Under no circumstance should an Arch Linux bug/feature be reported elsewhere.

Are all three packages found in the aur official?

[ejalxndr]

millennium is the only package maintained/provided by us - it's the only needed one.

I seem to run into an error on build with the AUR package, using CachyOS, error below :

Definitely an issue with your base system.

[m1neral-rocks]

idk if you figured it out by now but you probably either ran out of space or btrfs ran out of Inodes or whatever they're called

[pinguinman0]

Oh yes thanks, it was my rust package that was faulty. After an update it went ok.

AUR has re-opened just after the latest release so the CI still failed, AUR needs updated

[Khrouhman]

Unsure if this is related to AUR but the new steam client on Cachyos does not work with Millennium 3.6.1-1
