But the error message only appears by opening the contacts app. All of the other apps work without problems.
Hey Michael.
There is indeed a bug in the last version. This is not compatible with nextcloud 15. Please either downgrade to 3.1.3 or upgrade nextcloud to 16/17, or wait for the next fix incoming next week!
Thanks for the fast response. Then was my assumption right.
By the way: Is there generally a option (app history) to downgrade apps. Or is this only with a backup possible?
Yes, you can uninstall the contact app, download an old version from the app store, and extract the contacts.tar.gz in your apps folder. Then enable it on your instance
1.) You can use e.g. WinSCP to copy the files to the Raspberry Pi.
2.) You can use tar or the Midnight Commander (mc), if it is installed on your server.
3.) The apps folder is a sub directory of the Nextcloud root directory.
Thank you very much. The downgrade was successful. Although it was a bit tricky. To got access to the nextcloud folder I had to change “PermitRootLogin=Yes” in “sshd_config”. After I’ve changed the folder of contacts app, the apps works now without problems.
After the procedure I changed “PermitRootLogin=No”.
Mind to reset that parameter again to keep your server secure. Usually you should login as user “pi”, copy files to the server and then move them to the destination directory.
