Problem syncing calendar with Gnome Evolution and CalDav

2113225 shared this problem 49 days ago


I am having some problems with CalDav sync using GNOME Evolution. It seems that calendar items created elsewhere sync fine to my computer and are visible in the Evolution client. However, items created through Evolution don't sync back, and I get the following error message shortly after creating a new calendar item. I get the same error if I try to manually refresh.

The calendar backend servicing “Calendar” encountered an error.

The reported error was “Failed to put data: HTTP error code 412 (Precondition Failed)”.

Anyone experienced something similar? I haven't found any information at least.
