Hello,
I was using Owncloud 8.1.12 with the calendar app installed until the server was struck by a disastrous data corruption. All I have left is a backup of the SQL database.
I try to retrieve the data that was in the calendars so, I set up a new server (debian 8) and re-installed owncloud 8.1.12 from source. Veyrthing works fine yet, I cannot install the calendar app (or any other app). I suspect that the appstore no longer works for this release.
Error in logs: {"reqId":"lFSeBVPvJKzCG6pE5IY1","remoteAddr":"10.50.1.100","app":"core","message":"Could not get application, content was no valid XML","level":3,"time":"2018-02-07T14:21:31+00:00"}

Is is still possible to install the calendar app in Owncloud 8.1.12 ? The work planning of 30 people is at stake.
Thank you.
