after upgrading nextcloud from 27.0 to 27.0.1 I am getting the following errors. What could be the issue? I am pulling the latest apache image. Dockerfile and versions.php is right below.

Iā€™d be most concerned about the ā€œCanā€™t start NC because of versionā€ and ā€œdowngrading is not supportedā€ messages than the missing IMAP library.

You say you ā€œupgradedā€ - do you have the logs from that? How did the update/upgrade process go?

Since youā€™re running a customized image, youā€™ll have to keep track of changes that happen upstream and make sure youā€™re accommodating them. I see youā€™re using some variation of the old supervisord examples stuff - not sure if anyone has tested it with recent image changes.

Upstream moved to Bookworm recently. Thatā€™s one bit that might be different:

I got it working now with the help of XtraLarge who had the problem himself and looked into it. The purge command basically removed needed dependencies so just removing it from the Dockerfile solved the issue. My working Dockerfile is in the GitHub Issue.
