Arch Linux User Repository

Everyone can now participate in the general package update process! The process is almost entirely automated, these are the necessary steps:

1. Create an MR with your changes to the source repo (the firedragon folder contains the files of this repo)
2. Wait for a maintainer to review and merge it
3. Done! When merging, the PKGBUILD will automatically be deployed to AUR via the CI pipeline.

We are finally there! After being frozen on version 119 and investing quite some time improving the app, Firedragon now has an entirely new base!

Please see the Announcement post:

https://forum.garudalinux.org/t/new-firedragon-major-version-is-out/34585

Looks like firedragon 95.0-1 is currently failing to build:

Anyone able to get this to build recently?

edit: I was able to get 92.0.2-3 to build on a clean build VM. Not sure why it was failing for me in my previous post

My builds seem to be freezing at this point. It doesn't actually fail, but stalls here forever

@dr460f1r3 can you merge the PKGBUILD I mentioned?

I managed to find the issue; some edits to the PKGBUILD fixed it, but it does still end up resulting in what @prg mentioned with the rust errors:

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file build| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

Ah, I remember why I have difficulty with building in chroots:

It can install everything it needs in preparation for building packages but, every time it needs to grab dependencies for PKGBUILDs, it fails and says:

sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges

But this is weird because neither of these is the case for my system :/

I can't use a chroot for building if doesn't do that

(I use Paru for the AUR, and it has support for chroots, but I always get this problem)
