Hi! This was a known packaging issue where liblzma version isn’t correct… Could you try manually installing liblzma for 5.4 version and see if it works?
OK, I try to install, doesn't work, but I fixed it in this way: 1.- Extracting the AppImage content 2.- Deleting the liblzma inside the Appimage with "rm squashfs-root/lib/x86_64-linux-gnu/liblzma.so.5" 3.- Then making the AppImage again. Looks like the problem is the "liblzma.so.5" file
