Re: Removing packages from unofficial repositories
Hi all, I recently decided to migrate my Debian system away from deb-multimedia.org, where official packages exist. I used apt preferences to help me downgrade packages from deb-multimedia back to Debian testing, where an alternative version from testing exists. However, I would expect that most users would not have the patience to do this via apt preferences, and if there is an easier way, I was not aware of it. AFAIK the apt_preferences method is rather simple: Package: * Pin: release o=Debian Pin-Priority: 1001 With that setting 'apt-get dist-upgrade' downgrades DMO packages to official ones. At least it did in my case. For me, finding out the correct preference setting was the hardest part here :) -- With best regards, Vitaliy Filippov -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.

Re: Removing packages from unofficial repositories
Does it work if you have Debian, deb-multimedia, another third-party repo, and you just want to remove deb-multimedia? If you have other 3rdparty repos, you'll also need to set 1001 for all of them (except DMO), that should be enough. And of course strictly speaking it may be unsafe, but I think it's OK in case of debian-multimedia... -- With best regards, Vitaliy Filippov -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.

Simon wanted a general, user-friendly way to deal with situations like this. This is neither. And of course strictly speaking it may be unsafe, but I think it's OK in case of debian-multimedia... Every downgrade whether from DMO back to Debian or within Debian runs the risk of running into the kinds of breakage inherent to downgrades (as indicated in the quote I gave earlier). I don't think that risk should be downplayed. Ben -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Removing packages from unofficial repositories
Hi all, I recently decided to migrate my Debian system away from deb-multimedia.org, where official packages exist. I used apt preferences to help me downgrade packages from deb-multimedia back to Debian testing, where an alternative version from testing exists. However, I would expect that most users would not have the patience to do this via apt preferences, and if there is an easier way, I was not aware of it. I'm writing to suggest that in the long term, Debian's package management should have a general, user-friendly way to deal with situations like this, such as a mechanism to remove a repository subscription, and all package versions that came from it, while uninstalling as few as possible of the reverse dependencies. Can anyone suggest which Debian package it would be appropriate to file this as a bug on?

I don't think there is any appropriate package to file such a bug on as, there can be no general way to downgrade, ever. To quote from our infobot on irc: Downgrading is not, nor will ever be supported by apt. Programs change their data in a way that can't be rolled back, and package maintainer scripts support upgrades to new config file formats but not downgrades. The infobot further suggests in order to remove deb-multimedia.org packages: If you want to remove the packages from deb-multimedia.org and reinstall the packages from Debian repositories, one could do this: dpkg --remove --force-depends $(aptitude search '?narrow(?version(CURRENT),?origin(Unofficial Multimedia Packages))' --disable-columns -F%p); remove the dmm repository from sources.list; apt-get update; apt-get install -f; install the still missing packages which were removed in the former process ... It is an unfortunate consequence of using third party repositories that the process is so unfriendly to users. Since the state of the official multimedia packages in Debian has vastly improved in recent releases, fortunately fewer and fewer users have to go through this unpleasant process.
