Public bug reported: While trying to upgrade from 18.04 to the development version 18.10 using "update-manager -d" the upgrade aborts before "getting new packages". A windows pops up with the following information:
Error during upgrade A problem occurred during the update. This is usually some sort of network problem, please check your network connection and retry. E:Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh-cache > /dev/null; fi', E:Sub-process returned an error code This is what is shown in the terminal: (update-manager:24678): dbind-WARNING **: 16:51:39.742: Couldn't register with accessibility bus: Did not receive a reply.
