As reported, this is an issue on Debian-based distributions, but one reporter said they use Arch, so it should be considered a Linux issue.
I also use the AppImage but wish the program was built specifically for Debian, or at least Ubuntu, so it could be loaded from the product repository. I'm not a fan of Appimage distribution for programs.
My version of Linux is Linux Mint.
Thank you for letting us know this is being looked at. It's a critical issue, and until it's fixed, I'll switch to SuperSlicer, which, to be honest, is getting better. The only reason I still use Cura is that I'm better at it. SuperSlicer does some things better than Cura, and is catching up fast.
