Anything else showing up in /var/log/messages when you try to update? To confirm, you are using the "Update" button to start the update or something else?
Hi dlavigne,
thanks for your answer.
I'm using the "Update" to start the update. That's correct.
Here the contents of /var/log/messages after pressing the update button:
Feb 17 12:43:50 freenas manage.py: [common.pipesubr:71] Popen()ing: /sbin/umount -f '/mnt/primary/jails_3/owncloud_1/media'
Feb 17 12:43:51 freenas manage.py: [middleware.exceptions:37] [MiddlewareError: There was a problem creating the PBI]
Interesting. IIRC there are other forum posts on how to upgrade OwnCloud manually (eg not using the Update button). If you find one that works, please post the URL here so other readers of this post can benefit from it.
