Describe your issue

If you get an apt error while try to upgrade collabora, you can try this solution

1. Login with ssh
2. sudo -i
3. cd /usr/share/keyrings
4. wget http://www.collaboraoffice.com/downloads/gpg/collaboraonline-release-keyring.gpg
5. cd /etc/apt/sources.list.d/
6. nano collabora.list
7. change to:
   deb [signed-by=/usr/share/keyrings/collaboraonline-release-keyring.gpg] https://collaboraoffice.com/repos/CollaboraOnline/CODE-debian11 ./
8. apt update → no errors
9. Perform updates with the admin GUI → no errors

Perhaps there’s a more beautiful solution but in my case it works.

Thanks a lot for your post !

I had to do wget https://www.collaboraoffice.com/downloads/gpg/collaboraonline-release-keyring.gpg to work fine, the port 80 seems closed and the download fails otherwise.

Great job !

Thank you!
That was a good solution, apt works again and apt and app upgrade went super smooth.

Thank you!
