SUMMARY I've subscribed to a work calendar using the same URL as in Thunderbird, but I get no error messages (in the UI or command line) and none of the events in the calendar show up STEPS TO REPRODUCE 1. Go to "Add calendar…" 2. Select "iCal Calendar File" 3. Paste the URL in the filename field (I also tried replacing "webcal" with "https" and "http" in the URL) 4. Check "Read only" and uncheck "Enable file monitoring" 5. Save OBSERVED RESULT No error message or any indication of failure whatsoever, but also none of the events from the calendar show up. The folder properties maintenance tab shows size as 0. EXPECTED RESULT The calendar should be loaded *or* an error should be displayed. SOFTWARE/OS VERSIONS Arch Linux KDE Frameworks 5.60.0 Qt 5.13.0 (built against 5.13.0) The xcb windowing system ADDITIONAL INFORMATION I was able to set up a CalDav calendar, so there's no problem with connectivity or configuration in general. This is a new profile, just created today.
Utterly broken workaround: 1. Go to general settings 1. Click the offending calendar 1. Click "Restart" At this point the calendar events show up and the calendar is *duplicated* in the "Calendar Accounts" list. Removing what I thought was the "new" calendar removed *both* of them, and after re-adding the calendar I can no longer reproduce.
After changing the URL from "webcal://" to "https://" I was able to reproduce, except this time the calendar is *not* duplicated. Happy days! Now that just needs to be the default path to a working calendar.
