Unable to update Calendar app

Calendar app not possible to Update or even download and activate


I tried to update the calendar app. It failed with no descriptive error. So I removed it to try a fresh download and “activation”. This is the result.

Did you try occ?

occ app:install -vv -- calendar



It appears the server/container your Nextcloud instance is running on/in has broken DNS resolution.

At least based on the error message in the screenshot you posted.

You can easily test this by:

  • confirming DNS resolution within your Nextcloud instance at the command line with curl or any number of things
  • confirming you can’t install/update any other apps (you specified Calendar, but this problem should impact other apps too)

Well everything else worked flawlessly - also updating another app.

It worked using occ. Thank you @ernolf.
