Thought I was hitting this same issue - turns out it wasn't quite the same as I did NOT have dconf-editor available.
Ended up figuring this out as follows: virt-manager --debug <...go into preferences screen...> (virt-manager:10411): dconf-WARNING **: 03:20:30.256: failed to commit changes to dconf: Failed to execute child process “dbus-launch” (No such file or directory) [Fri, 29 Nov 2019 03:20:30 virt-manager 10411] DEBUG (preferences:97) Showing preferences apt install dbus-x11 all good now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826271 Title: virt-manager does not save preferences To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/d-conf/+bug/1826271/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
