In Shelly, jack appears in both Packages and AUR sections.
(Can’t embed more than 1 picture because of the newbie rule(?), but it is also in the AUR section)
Here’s the output from pacman:

I don’t see this package on https://packages.cachyos.org/, so it is provided by the CachyOS team, but lives as an AUR package, and still has an entry in the normal packages section? That is quite confusing. If I go ahead and remove all of this and replace it with jack2 and need to revert afterwards for whatever reason, I need to get it myself from the AUR right (even though that means it is no longer packaged by CachyOS team anymore)?
