I have the problem after updating to 6.4.

Do you also get this error when updating to Zammad 6.4.2/6.5?

sl_poly · April 3, 2025, 8:41am

Yes, I tried 6.5 today. Same problem. Any ideas?

MrGeneration · April 3, 2025, 9:54am

There is no telegram.rb in Zammads source code (anymore)

So if I’d had to guess: You migrated at some point (with all filesystem files; not recommended) which is why your package manager does not track these affected files.

Dangerzone

You’ll have to manually drop affected files.
This is quite dangerous, you should be fine if you remove everything in /opt/zammad/ except for config/ and storage. You will need to force a reinstallation of the package afterwards.

Proceed at your own danger, have a backup.
