https://doc.owncloud.org/server/10.0/admin_manual/maintenance/upgrade.html read and follow the steps in order to update properly your ownCloud instance.

I'm pretty sure you've messed up with the update, that's why the integrity check is crying. Hopefully is something you can recover from, but be careful with what you're doing.


#3

I can not control integrity because it does not work


#4

well, how did you upgrade? Were you following the steps provided in the link @jvillafanez posted?


#5

Are you serious? If yes: there seems to be something terribly wrong. That file should not be bigger than 1-2 kbytes....

Looks like you have inside your ownCloud-folder another complete ownCloud folder. Looks like there went something wrong with copying files.


#6

I'm facing the same issue.
Yesterday I updated from 9.1.8 to 10.0.7 as described in the docs:
- backup database and owncloud software directory
- backup data directory (have it outside of software directory)
- delete old owncloud software directory
- extract new owncloud software to old location
- copy config.php from backup to extracted software directory
- switch on maintenance mode, occ upgrade.

The docs are not quite good about what to pay attention regarding switch to owncloud market, contacts and calender and so on...
but somehow I could manage to get owncloud running again. Calender and Contacts sync also work like expected.

Only issue I currently see is the above mentioned error when I run e.g. occ status


#7

already tried to uninstall contacts and calendar and re-install it... but didn't help... still get the error when running occ status.


#8

To me this looks like some sort still existing but outdated / old files of a previous installation / version, either on the filesystem or in some sort of cache of PHP, redis or similar.


#9

I renamed the old owncloud directory and extracted the new version to the old location. So there can't be any old files from previous installation.

And when I execute occ from command line, where should there be a cache?!??


#10

Maybe this is something you need to research? I think there could be all sort of caches involved like e.g. redis, memcached and similar.

And if i'm checking i'm checking my local ownCloud 10.0.7 installation i don't have a file like:

/var/www/owncloud/apps/dav/appinfo/registercommand.php

like @rikidevelop has posted in the initial description. I think this could be another example for having old files staying around on e.g the filesystem.


#11

all the files mentioned in the error message exist in my installation:

I think the _ in filename register_command.php in the initial post of @rikidevelop maybe was removed by the forum software.

hm, did a little strace:

after it tries to open /path/to/owncloud/lib/composer/pear/pear-core-minimal/src/CardDavBackend.php it throws the exception...


#13

And i think at least for the register_command.php this is the source of your problem. If i'm downloading https://download.owncloud.org/community/owncloud-10.0.7.tar.bz2 and check the archive or check my local installation of ownCloud 10.0.7 i can't find a register_command.php in apps/dav/appinfo/


#14

Thanks for you reply.
It animated me to try it once again with a completely fresh owncloud directory.

And even I already tried that approach, now it works.

So: thanks a lot for your patience :slight_smile:
