Here's a cleaner variation of the workaround: sudo dpkg --purge --force-depends libpostproc52 sudo apt-get install libpostproc52 sudo apt-mark auto libpostproc52
The first line purges the package without removing any of the packages that depend on it. (This is fine, since we're going to reinstall the dependency immediately.) The second line reinstalls the package. The third line marks the package as automatically-installed (as it is in a stock ubuntu system), so the system knows to treat it as a dependency rather than something the user manually installed. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libav in Ubuntu. https://bugs.launchpad.net/bugs/1286836 Title: package libpostproc52 6:0.8.10-0ubuntu0.13.10.1 failed to install/upgrade: libpostproc52:amd64 6:0.git20120821-4 (Multi-Arch: no) is not co-installable with libpostproc52 which has multiple installed instances Status in “libav” package in Ubuntu: Confirmed Status in “libpostproc” package in Ubuntu: Confirmed Bug description: - ProblemType: Package DistroRelease: Ubuntu 14.04 Package: libpostproc52 6:0.8.10-0ubuntu0.13.10.1 ProcVersionSignature: Ubuntu 3.13.0-14.34-generic 3.13.5 Uname: Linux 3.13.0-14-generic x86_64 ApportVersion: 2.13.2-0ubuntu5 Architecture: amd64 Date: Mon Mar 3 00:57:47 2014 Dependencies: gcc-4.9-base 4.9-20140222-0ubuntu1 libavutil51 6:0.8.10-0ubuntu0.13.10.1 [origin: unknown] libc6 2.19-0ubuntu2 libgcc1 1:4.9-20140222-0ubuntu1 multiarch-support 2.19-0ubuntu2 ErrorMessage: libpostproc52:amd64 6:0.git20120821-4 (Multi-Arch: no) is not co-installable with libpostproc52 which has multiple installed instances InstallationDate: Installed on 2013-12-12 (79 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) SourcePackage: libav Title: package libpostproc52 6:0.8.10-0ubuntu0.13.10.1 failed to install/upgrade: libpostproc52:amd64 6:0.git20120821-4 (Multi-Arch: no) is not co-installable with libpostproc52 which has multiple installed instances UpgradeStatus: Upgraded to trusty on 2014-03-02 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libav/+bug/1286836/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
