I’m running a mailcow docker server on Ubuntu 18.04. The command “git log” shows, that the last commit was from ShadowGhost at Sun Dec 16 11:22:09 2018 +0100. Therefore I had no update.sh script for updating.
At first I’ve tried the old manual update process described on https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_update/. After the update every container was running, but I wasn’t able to send an email. It seemed, that the database was in a bad state.
At second, I’ve recovered the old installation, downloaded the update.sh script and started it, but also with no full success. The “git merge” failed. I tried to move all own files to another place and after adding a special option ( –allow-unrelated-histories) to the merge command, I was able to finish the update process. But the result was similar to the first update process. I’m not able to send any emails.
Is my mailcow server to old for a direct update? Should I try to update at first to an older version?
If so, what commit should I use at first?
Thanks in advance,
