Unable to delete shared calendar


I’m using nextcloud version 20.0.4. When removing a calendar that has been shared with me by clicking on the “unshare with me” button, after the end of the timeout, I get the following message : “an error occurred, unable to delete the calendar”. As shown in the image below :

I cannot remove the calendar. Anything I can do to resolve this?

Thanks in advance.


Having the same problem on our 19.0.6 installation.
