libfarstream-0.1-0 not installable due to conflict with libgstfarsight0.10-0

[Andrea Corbellini]

Because of this conflict, telepathy-butterfly cannot be installed/upgraded.

The following packages have unmet dependencies:
  libfarstream-0.1-0: Conflicts: libgstfarsight0.10-0 but 0.0.31-1ubuntu3 is installed.

Status changed to 'Confirmed' because the bug affects multiple users.

python-papyon needs to be moved from python-farsight to python-farstream.

Also, it's questionable why libfarsight and libfarstream should conflict instead of be installable in parallel. That would make upgrades a lot easier.

[Xavier Claessens (zdra)]

gnome-core-devel also needs to be updated to depend on libtelepathy-farstream-dev instead:

The following packages have unmet dependencies:
 gnome-core-devel : Depends: libtelepathy-farsight-dev (>= 0.0.19) but it is not going to be installed

The proper disposition for papyon is removal. Filing another bug for that.

[Ken VanDine (ken-vandine)]

farstream and farsight do in fact conflict, the proper fix was the removal of papyon.

[Paul (i41bktob-launchpad-net)]

given that python-papyon is a dependency of emesene and telepathy-butterfly, the latter a recommendation of empathy, removing it is not zero-impact either.

[Joseph Wakeling (webdrake)]

Given that a safe-upgrade is still not possible and a full-upgrade wants to remove telepathy-butterfly, can you advise how to proceed? The "Won't Fix" is confusing given that the problem does not merely affect papyon and farsight.

[Andrea Corbellini (andrea.corbellini)]

@Joseph: telepathy-butterfly can be safely removed, because the MSN protocol functionality is also brought by telepathy-haze. So, I suggest you to proceed as follows:

1. remove telepathy-butterfly;
2. remove all its dependency (the ones that conflict): libgstfarsight0.10-0 libtelepathy-farsight0 python-farsight python-papyon;
3. proceed with the upgrade.

After those steps, the upgrade should have completed successfully and MSN should still be an available protocol.

[Joseph Wakeling (webdrake)]

@Andrea: thanks, that works. :-) It was actually one of aptitude's suggested full-upgrade solutions, but I didn't realize telepathy-butterfly was safe to remove.
