Mystery solved and apologies for the invalid bug report. There was an old gnome-power-statistics in /usr/local/bin
This laptop has been updated from 12.04 to 16.04 without skipping any intermediate steps and apparently at some point I felt the need to install gnome-power-statistics manually. ** Changed in: gnome-power-manager (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617866 Title: gnome-power-statistics dies with " error while loading shared libraries: libupower-glib.so.1" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/1617866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
