The issue was caused by our auto-backport of LXC and LXD dependencies so we can guarantee a consistent experience on all Ubuntu releases.
This may indeed cause some occasional breakage when one of those packages revs their SOVER which is what happened there. We won't be rebuilding all the affected bits in our PPA. What I could recommend you do though is just pin the affected packages to the archive version. protobuf specifically is only needed for criu which is an optional dependency. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to protobuf in Ubuntu. https://bugs.launchpad.net/bugs/1486192 Title: libprotobuf9v5 : Conflicts: libprotobuf9 but 2.6.1-1 is installed.

(4) During regular system upgrade in the last two days or so, I get the following: The following packages have unmet dependencies: libprotobuf9v5 : Conflicts: libprotobuf9 but 2.6.1-1 is installed. The following actions will resolve these dependencies: Remove the following packages: 1) libegl1-mesa-dev 2) libgles2-mesa-dev 3) libmirclient-dev 4) libmircommon-dev 5) libprotobuf-dev 6) libqt5opengl5-dev 7) libqt5sensors5-dev 8) libqt5webkit5-dev 9) libqt5websockets5-dev 10) libqt5xmlpatterns5-dev 11) python-protobuf 12) qt3d5-dev 13) qt5-default 14) qtbase5-dev 15) qtdeclarative5-dev 16) qtlocation5-dev 17) qtmultimedia5-dev 18) qtpositioning5-dev 19) qtscript5-dev 20) qttools5-dev 21) ubuntu-sdk 22) ubuntu-sdk-libs-dev Keep the following packages at their current version: 23) libprotobuf9v5 [Not Installed] Leave the following dependencies unresolved: 24) qtcreator recommends qt5-default 25) qtcreator recommends qtbase5-dev 26) qtcreator recommends qtdeclarative5-dev 27) qtcreator-plugin-ubuntu recommends ubuntu-sdk Accept this solution? [Y/n/q/?] I tried to let Ubuntu calculate multiple other solutions but all proposed look dubious to me and I've not tried any of them. I particularly interested in item 23 above but am not clear how to proceed. When I've explicitly tried to install libprotobuf9v5 directly, a much more terrible solution is proposed. From what I can tell with Google search, "https://www.google.com/search?q=libprotobuf9v5+%3A+Conflicts%3A+libprotobuf9+but+2.6.1-1+is+installed.";, this appears to be caused by an upstream renaming of the package from libprotobuf9 --> libprotubuf9v5, as indicated in the various change logs.
