Bug#990515: release.debian.org: buster->bullseye upgrade issue: sshfs is not upgraded due to fuse/fuse3
Package: release.debian.org
Severity: normal
let's start a discussion here and once we found a package to upgrade,
turn this into an unblock request.
sshfs is sometimes kept at the buster version because of some dependency
mess of fuse/fuse3.
This usually shows up in large metapackages like freedombox or kde-full
with --install-recommends enabled. Probably because there are additional
dependency paths on fuse.
* sshfs/buster depends on fuse
* sshfs/bullseye depends on fuse3
* fuse still exists in bullseye as a real package
* fuse3/bullseye has Conflicts/Replaces: fuse and a
versioned Provides: fuse (= ${source:Version})
Upgrading would require kicking out fuse and installing fuse3 but apt
does not do that, as so often.
This isn't solved by a followup distupgrade either.
I haven't found a solution adding more Breaks: fuse to various packages
to solve this cleanly. Naturally I would have suggested to add a
transitional fuse binary package to src:fuse3 which just
Depends: fuse3 (= ${binary:Version}) and adjust the Breaks/Replaces in
fuse3 to fuse (<< 3). src:fuse then should drop its fuse package (or
rename it to fuse2 while adding a '2' to all filenames).
I'm also not convinced that fuse3 is a real replacement for fuse: it has
symlinks foo -> foo3 for all binaries and manpages. But the initramfs
hook only does 'copy_exec /sbin/mount.fuse3 /sbin', it does not care
about /sbin/mount.fuse
