Hello @s09bQ5, do you know which tools were used to make this AppImage?

Squashfs image uses xz compression, this version supports only zlib, zstd.

This automated test supports only zlib, zstd compression. I am wondering which AppImage generation tool uses xz compression.

This automated test supports only zlib, zstd compression. I am wondering which AppImage generation tool uses xz compression.

We are using appimagetool --comp xz .... to create the AppImages. The appimagetool is built from Git tag 13 of the AppImageKit repository.

Can you please retry with --comp zstd or without --comp? Thanks. While the spec doesn't mandate a certain compression (yet), this automated test currently supports only zlib and zstd compression.

We made a new stable release 7 hours ago. I don't think we will replace those binaries before our next release in July.

Wouldn't it make more sense to replace the runtime binary used for the test with a new one that is capable of mounting xz compressed squashfses? Why do the test use https://github.com/AppImage/appimage.github.io/releases/download/deps/runtime-fuse2-x86_64 instead of https://github.com/AppImage/AppImageKit/releases/download/13/runtime-x86_64? The latter can mount our AppImage without any problems. Does it really need to be statically linked?

Yes, we are transitioning to the statically linked runtime soon.

And possibly standardize on zstandard (no pun intended):

Out of curiosity, what was your rationale for choosing xz? In our tests, zstd outperformed everything else.

[s09bQ5]

Not even current HEAD of AppImageKit supports zstd.
