I had this problem but with a different program. In my case it was the 'zenity' program failing to load after an upgrade resulting in the system failing to boot. The workaround suggested in https://bugs.launchpad.net/timeshift/+bug/1516255 worked for me.
The problem seems to be a manual installation of Google's protobuf conflicting with libmirprotobuf. I fixed it by uninstalling Google's protobuf (by removing all relevant looking things from /usr/local/lib and /usr/local/include) and then reinstalling libmirprotobuf (which is libmirprotobuf3 on Ubuntu 16.10). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1527137 Title: libmirprotobuf.so.3: undefined symbol: _ZNK6google8protobuf11MessageLite25InitializationErrorStringB5cxx11Ev To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1527137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
