Hello @sasa,
there is a similar posting at Owncloud 10.1.1-2019-04-23 - Cannot upgrade - RESOLVED - #2 by damrose. Maybe this already helps.
Error 416 means that something during the app setup went wrong. The upgrade is aborted and
the App Center then tries to return to the last status and installs the previous version. This fails, because the ownCloud app expects an empty database upon installation and there uninstalls the app.
A fix for this problem is work in progress.
Best regards,
Nico
