For the record: This happened to me during a distribution upgrade from 13.10 (saucy) to 14.04 (trusty). When it happened, the release upgrade tool interrupted itself with a dialog box containing this alarming and not very helpful message: Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a).
This dialog box was modal, preventing me from scrolling or copying the text in the Terminal widget to see what really happened. The text visible in the Terminal widget did not show up in any of the /var/log /dist-upgrade/* logs, but it was clearly a python exception and stack trace. Upon closing the dialog box, the upgrade continued, contrary to what the alarming message stated. (I guess the message was referring to one particular package, not the overall release upgrade, but most end users wouldn't know that, and even if they did the message didn't state which package.) As the upgrade continued, I was unable to copy & paste the stack trace before it was pushed out of the Terminal widget's rather short scroll buffer. -- You received this bug notification because you are a member of Desktop 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/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
