Describe your issue
If you get an apt error while try to upgrade collabora, you can try this solution
- Login with ssh
- sudo -i
- cd /usr/share/keyrings
- wget http://www.collaboraoffice.com/downloads/gpg/collaboraonline-release-keyring.gpg
- cd /etc/apt/sources.list.d/
- nano collabora.list
- change to:
deb [signed-by=/usr/share/keyrings/collaboraonline-release-keyring.gpg] https://collaboraoffice.com/repos/CollaboraOnline/CODE-debian11 ./ - apt update → no errors
- Perform updates with the admin GUI → no errors
Perhaps there’s a more beautiful solution but in my case it works.
