@LukasReschke Caused by the old updater ...

@karlitschek Another argument to move to the new version ;)

@Rouzax This is the old updater, that only works if you have this method available. This should also be listed in the admin settings check. Sadly we can't do much here for the old updater and we wrote a new one, that is a lot simpler and doesn't require this method anymore. Feel free to test it. See https://help.nextcloud.com/t/test-our-new-work-in-progress-upgrader-script/1214 for more details

@MorrisJobke Agreed. I'm just not sure we we still have the time to bring this into shape for the next release. Aka. Add the needed features and do testing. I suggest to do this for the next one.

Therefore we only show this when a "I'm super sure to use this, because it is still in beta" config switch was set ;) Then eager people can set it and try the new updater without copying files around. And on the other side we are safe, because it is not enabled by default :)
