I opened an issue on the Setzer Github (https://github.com/cvfosammmm/Setzer/issues/404), from which the creator referred me to the Ubuntu bugtracker. I am copying over what I managed to figure out:
After searching around a bit on similar issues I believe it's an instance of https://bugs.launchpad.net/apparmor/+bug/2046844 and copying the workaround for the similar issue at https://github.com/hugolabe/Wike/issues/181 appears to work. Create the file /etc/apparmor.d/setzer with the following contents: # This profile allows everything and only exists to give the # application a name instead of having the label "unconfined" abi <abi/4.0>, include <tunables/global> profile setzer /usr/bin/setzer flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/setzer> } I don't know exactly what this does though, besides that it somehow makes apparmor happy! ** Bug watch added: github.com/cvfosammmm/Setzer/issues #404 https://github.com/cvfosammmm/Setzer/issues/404 ** Bug watch added: github.com/hugolabe/Wike/issues #181 https://github.com/hugolabe/Wike/issues/181 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064781 Title: setzer does not launch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/setzer/+bug/2064781/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
