Contacts and calendar apps disabled after upgrade to 9.0.1

[codethief]

Steps to reproduce

1. Install ownCloud 9.0.0
2. Enable contacts and calendar apps, add some contacts & calendars / dates
3. Upgrade to ownCloud 9.0.1 using apt-get and ./occ upgrade

Expected behaviour

The apps "contacts and calendar" should stay enabled (or get reenabled once the upgrade is finished).

Actual behaviour

The contacts and calendar app got disabled (the data has been preserved, though). I only noticed this by chance (namely because I wanted to edit a contact through the web interface after the upgrade). The output of ./occ upgrade (see below) was all green, which – at least to me – suggested that everything worked fine and I wouldn't need to look at the output carefully, let alone reenable the apps again.

Hi,

disabling 3rd-party apps during an update/upgrade is the current expected behaviour. A discussion about that is available here: #18312 (and i think at quite a few other issues).

Oops, I guess I should've looked through more than just the first page of search results for "is:issue is:open apps disabled upgrade" here on GitHub. Thanks for the link!

When doing an update (e.g. 8.2.2 -> 8.2.3) and not an upgrade (e.g. 8.1.6 -> 8.2.3) it should be also safe to run occ upgrade with the --no-app-disable command: https://doc.owncloud.org/server/9.0/admin_manual/configuration_server/occ_command.html#command-line-upgrade

As said. Expected behaviour for now. Closing this.
