Hi, this message appears because this AppImage works with fuse3

Are you using gentoo? You might be affected by a bug in the new runtime.

There is actually a fix in the works, but it is taking a while for it to be merged.

iirc the problem is that on gentoo /usr/bin/fusermount doesn't have read permission for the user. Which the new runtime needs.

So the only thing you can do in the meantime is to change the permissions of /usr/bin/fusermount so that it can be read by the user.

This other trick might work in the meantime, if it works you don't have to be messing with /usr/bin/fusermount

FUSERMOUNT_PROG=$(which fusermount) ./Steam-1.0.0.79-2-x86_86.AppImage

FUSERMOUNT_PROG can be defined in your bash_profile or zprofile, etc btw.

Edit: Btw you might want to re-download the appimage as there has been some fixes.
