File not found by downloading a folder

Nextcloud version (eg, 20.0.5): 23.0.0
Operating system and version _: Linux 5.14.15-Unraid x86_64
Apache or nginx version (eg, Apache 2.4.25): nginx 2021/10/24
PHP version (eg, 7.4): 7.4.26

The issue you are facing:
I want to Update the newest Version of Nextcloud 23.0.2.
But the " Check for expected files" gives the error " file no found" ( look at the picture )

Is this the first time you’ve seen this error? (Y/N):
If i want to download a folder, I get the same Error “file not found” but if i download a file, it passed.

Steps to replicate it:

  1. going to uploader
  2. check updates
  3. waiting to get the error


  1. check a folder
  2. click on download
  3. waiting to get the error

Can you upgrade vom shell? Perhaps you must use another username.

sudo -u www-data php updater/updater.phar
Post errerors.

Read this documentation.

Additional hint:
If you click the line Fehler PHP Cannont use... you will find more details.

Normaly, I upgrade the docker via unraid. It seemed I have to wait for the newest version. But the error with the “file not found” is still there if I want to download a folder.

bc of unraid i can’t use sudo -u www-data

The error comes from the app groupfolder and was patched end of the january.
The error “file not found” by downloading a folder didn’t comes to the log field.

Maybe because the database ?

  • but I can download a file not a folder. It is ridicilous…

Maybe it isn’t gezipped or wrong gezipped ?

Sorry i do not understand your installation.
Cannot use OCP/Constants as Constants because the name is already in use at /config/www/nextcloud/apps/groupfolders/lib/Command/ACL.php#35
Is your installation path /config/www/nextcloud?
occ db:add-missing-indices works for you on /. Then the nextclooud path is /.

php updater/updater.phar
can not found the subdir updater in / ? updater is a standard directory in nextcloud installation e.g. / or /config/www/nextcloud?
occ updater/updater.phar
updater/updater.phar does not work with occ. This command is wrong.
