Summary of the issue you are facing:

Whenever I am trying install and use an app the install works fine and the app shows up in the top menu on the dashboard but the icon/image of the app is missing and when I click it the app doesn’t work. In some apps some small stuff is loading and in other apps only the lovely blue-ish background is showing.

Tested 2 apps so far: solitaire and deck. More info about the deck install can be found in a rejected issue on their github.

Steps to replicate it (hint: details matter!):

  1. Login as admin to NC
  2. Install an app
  3. Click on the app (notice the missing icon) in the top menu

Log entries

This log a snippet of when I click the icon in the top menu until the log stops rolling with loglevel “debug”. Any other loglevel prints nothing when doing this.

Other info

Things I’ve tested:

  • Reinstalling apps
  • Relocating extra-apps
  • Disable SELinux
  • Change permissions
  • Updating OS
  • Rebooting
  • Restarting httpd and php-fpm
  • files:scan-app-data

Any help on this is appreciated.

It does seem like an issue with every app installed in the additional extra-apps-folder. Am I missing something, like an option or some httpd stuff?

For quick reference, here’s my apps_paths:

occ config:list system (snippet) 
        "apps_paths": [
            {
                "path": "\/usr\/share\/nextcloud\/apps",
                "url": "\/apps",
                "writable": false
            },
            {
                "path": "\/usr\/share\/nextcloud\/extra-apps",
                "url": "\/apps-appstore",
                "writable": true
            }
        ],

Please see the Tip in Using custom app directories in the Admin Manual. It may be relevant in your case.

(Though it appears you’ve moved things around a few times between the linked Issue and this support thread).

Also, check your Apache error log for clues about the 404.

Not sure how I managed to miss that big, green tip box right there, but adding a symlink from <serverroot>/extra-apps to <serverroot>/apps-appstore did the trick. Thanks a bunch for all the help!
