I've followed this Guide: https://doc.owncloud.org/server/8.2/admin_manual/maintenance/package_upgrade.html
the link lead me to add latest repositories. i ran the install owncloud command afterwards, since the upgrade didn't want to upgrade it.
now i get this:
Set log level to debug Turned on maintenance mode Exception: Updates between multiple major versions and downgrades are unsupported. Update failed Maintenance mode is kept active Reset log level
The version is now showing to be 9.1.1.
how do i solve this issue? why did the menitoned guide lead me to install 9.x repositories? why does the upgrade not work then?
offtopic: why can't you update owncloud as easilly as wordpress and thousands of other web apps? there is always something that get's changed and not working afterwards.
also documentation is lacking explanations. for example:
Then use occ to complete the upgrade. You must run occ as your HTTP
user. This example is for Debian/Ubuntu:
it doesn't say you need to be in owncloud folder for this command to work.
