Upgrade to gives error: Failed opening required '\/appinfo\/v2\/remote.php'

i updated to from latest 12.x version. First i got
"PHP Fatal error: Declaration of OCA\FilesAccessControl\StorageWrapper::copyFromStorage(OCP\Files\Storage $sourceStorage, $sourceInternalPath, $targetInternalPath) must be compatible with OCP\Files\Storage::copyFromStorage(OCP\Files\Storage\IStorage $sourceStorage, $sourceInternalPath, $targetInternalPath) in /home/www/datentausch/apps/files_accesscontrol/lib/StorageWrapper.php on line 628"

and so i removed all /apps like told in

after that update went on and updated some apps.

but now i get
"app":“core”,“method”:“GET”,“url”:"/index.php/apps/files/",“message”:“Could not resolve checkManager! Class checkManager does not exist”,“userAgent”:“Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36”,“version”:“”}

,“message”:“require_once(): Failed opening required ‘/appinfo/v2/remote.php’ (include_path=’/var/www/nextcloud/3rdparty/pear/console_getopt:/var/www/nextcloud/3rdparty/pear/pear_exception:/var/www/nextcloud/3rdparty/pear/pear-core-minimal/src:/var/www/nextcloud/3rdparty/pear/archive_tar:/var/www/nextcloud/apps’) at /var/www/nextcloud/remote.php#164”,“userAgent”:“Mozilla/5.0 (Windows) mirall/2.3.2 (build 1) (Nextcloud)”,“version”:“”}

in webbrowser i get the message “ERR_TOO_MANY_REDIRECTS”

Anyone an idea what i need to do to solve this?

problem solved. disable the /apps by the occ command and did a manual upgrade over the current (not working) installation ( move files away, unzip the latest release, move config.php (and possibly data) back over).

That did the trick, when i came back in web it asked to update the apps and after that i could login again. Not sure if it was really needed to disable all the apps first, but that way it worked for me at least.

also seeing similar messages after upgrading to v14. When I installed the calendar app with occ, I could use it to access the admin interface but am unable to access files or do much of anything.

WebDAV doesn’t work so /index.php/apps/files/ returns the error above. I also get a lor of font errors.

I have a redirect in nginx that sends users from domain.com/nextcloud to cloud.domain.com. Not sure if that’s part of the problem. No idea how to test without it.

The version I installed also had 5900 extra files I had to remove during the security check.

Any idea how I can get this working again?
