I just did the above mentioned upgrade but it seems like systemd is not working as it should. If I run a command like systemctl start apache2 I get the message

Failed to connect to bus: No such file or directory

Oddly service apache2 start is still working. I had to start the upgrade twice because something went wrong the first time I did, so I think it might have something to do with that.

Is there a way to manually switch from upstart to systemd while maintaining all working services?

The transition is described in an Ubuntu guidance document, called "Systemd For Upstart Users."

  • I saw that article already, but got confusion by the headlines. "If you want to switch back to systemd, install the systemd-sysv and ubuntu-standard packages." That did the trick. Thank you very much!
