Hi, I am trying to push Calendarserver 5.x into Ubuntu Trusty (due to release on April 17). While testing I have found two issues. Any help to have them resolved would be great. 1. Earlier, for XML entries, I have distributed a sample accounts.xml file with the guid same as the uid (for ex. admin, test, etc.). However, with calendarserver 5.x, I can see that these kind of guids are considered invalid. Now, I figured out that the valid guid can be generated from the function 'str(uuid4()).upper()'. But how do I migrate the data from older guids to the newer guids? Is there any database update command that I can run? 2. Next, I have observed that for calendarserver 5.x, tasks are disabled when I access the calendar from Thunderbird. I am not sure if tasks have been disabled upstream or whether there is some compatibility issue with Thunderbird & Apple calendarserver. Any help in resolving these issues would be of great help as there are only a couple of days left for the Ubuntu LTS release. Regards, Rahul.
