Prompt "fusermount3": executable file not found in $PATH and cannot mount!

Please install fuse3 package, similar to #6856 37977

You can also create a symlink to fallback to fuse for mounting, tho it should only be in the case where fuse3 cannot be installed. See 37073.

If you are sure that fusermount3 is installed, which can be checked via a where fusermount3, and still cannot mount, it can possibly because of secure file permission (or paranoid, in that matter) of Linux.
