I was trying to set up iCloud Calendar on Evolution (3.28.5-0ubuntu0.18.04.1).
After everything settled, I found that I could not RECEIVE the calendar online, which says:
The calendar backend servicing “Personal” encountered an error.
The reported error was “Failed to read resource: HTTP error code 404 (Not Found)”.
However, when I add a new appointment in the Evolution, the appointment will also appeared on iCloud Calendar or masOS Calendar.
Therefore, I suppose my settings are correct because the pushing service works pretty well.
Is there anyone encountered this problem before? I am a newbie in Ubuntu, the Calendar function works perfect on Evolution in Manjaro, and the settings are all the same.
I have already read the posts on Ask Ubuntu, but no one has post questions like this.
The settings are as followings:
Find Calendars Shows Calendar List
Choose Calendar from Find Calendars and get URL
