You have been subscribed to a public bug: I ran do-release-upgrade from a terminal. The process eventually failed because of "too many errors". The root cause appears to be this:
Removing systemd-shim (9-1bzr4ubuntu1) ... Removing 'diversion of /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service to /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service.systemd by systemd-shim' dpkg-divert: error: rename involves overwriting '/usr/share/dbus-1/system-services/org.freedesktop.systemd1.service' with different file '/usr/share/dbus-1/system-services/org.freedesktop.systemd1.service.systemd', not allowed I appear to have worked around this by manually removing /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service, purging systemd-shim via `dpkg -P` and then doing `apt-get install -f`, which completed without errors. After that, another `apt-get dist- upgrade` was apparently enough to complete the upgrade. ** Affects: systemd-shim (Ubuntu) Importance: Undecided Status: Incomplete -- 16.04 to 18.04.1 ubgrade fails because of diversion of org.freedesktop.systemd1.service https://bugs.launchpad.net/bugs/1787540 You received this bug notification because you are a member of DX Packages, which is subscribed to systemd-shim in Ubuntu. -- Mailing list: https://launchpad.net/~dx-packages Post to : dx-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~dx-packages More help : https://help.launchpad.net/ListHelp
