[SOLVED] Downgrade aur package only showing versions of Jack2 with libsystemd

Hello fellow Linux users,

I have an issue regarding LMMS. I installed it through the arch support repos and it was running fine until carla and jack2 updated. I did some digging and found a bug somewhere. I reported the bug and details to LMMS, jack2 and carla. To then fix my issue as quickly as possible, I read the wiki on downgrading packages. I decided to downgrade carla and attempted to downgrade jack2 as well. carla downgraded completely fine, but jack2 can't downgrade. I went as far as to disable the arch repos for the moment to see if that helped. No such after both "yay -Syu" and a reboot (in case of temporary programs lingering). Downgrade still is only listing arch compatible versions of jack2 and seemingly has none that don't depend on libsystemd. Also if anyone is good with jack issues, here is my output from running the command "lmms" in the terminal:
Code: [Select]
*** WEAK-JACK: initializing
*** WEAK-JACK: OK. (0)

(lmms:3896): Gtk-WARNING **: 13:23:43.497: Unable to locate theme... (not important but repeats itself 19 other times)

Notice: could not set realtime priority.
Segmentation fault
In case it is necessary, I run Artix (non-UEFI booted for simplicity's sake) on a 10 year old Thinkpad (T430) with OpenRC, MATE DE,  Slick Greeter, the "yay" aur helper and the 5.18.10-artix1-1 kernel.

Can't you find these packages in your pacman cache?

Not that suprising as by default it only looks into archive.archlinux.org

Download jack from https://archive.artixlinux.org or invoke downgrade with --ala-url https://archive.artixlinux.org (not sure if it will work).

You can edit  /etc/xdg/downgrade/downgrade.conf "--ala-url" line to point to the artix archive like so:

--ala-url 'http://archive.artixlinux.org/'

This does work.

Best regards.

We should try to be kind to everyone.....we are all fighting some sort of battle.

As for LMMS, the issue was with kwidgetsaddons being updated by the Arch package. Downgrade kwidgetsaddons (5.101.0-1 => 5.92.0-1) to fix the LMMS issue. As for Jack2, it did not have anything to do with LMMS issues despite my initial research. I also configured downgrade to point to artix archive (thanks @conky60 and @capezotte )
