Dear, I upgraded my owncloud server from the last 9.x version to 10. All seems to work fine except the calendar. When I enter in the calendar the New Calendar and New Subscription in the left, doesn't appear. There is the waiting circle that rotate forever without result.
There are a few manual modifications needed to files and the database for 10.0.0 if you want to get this to work [1]. If you rely on a working calendar please revert to your oC 9.x backup and wait for the next release 10.0.1.
I#m facing the same problem, but as i'm not able to revert to 9.0 (complete server update) I#m wondering if this will be solved with the update for 10.0.0.1 .
Short version: does just waiting for the next version helps? or where can I find the manual modifications to make it work?
Yes, the known calendar issues will be fixed in the upcoming 10.0.1
The linked thread above contains the pointers where those are found. I don't have the time right now to do the search for you but you might be still able to find them on your own.
I've seen that the new version of OC is now out which fixes the Calendar problem. When I now run apt-get update && apt-get upgrade on my Ubuntu Server 16.04. kernel 3.13.0-77-generic the new version is not available. What is the reason for this? Why does it take so long to be integrated into the offcial sources from ubuntu?
There can be delays especially if they find some problems just before the release. You shouldn't worry about 1-2 weeks of delay and rather be happy that you didn't run into issues.
From what i can see from the following comment above the "stable" repositories are not containing ownCloud 10.0 by design and you need to switch to another repository to get 10.0.2:
