Thx verry much! Have disabled the Podcast app and then update working like a dream!
Indeed it was the podcast app. After I deactivated that, the upgrade worked without any errors

Thanks for your help!

Hi there,

I have also experienced this error while attempting to upgrade the podcast app. I am now stuck, as when I navigate to my nextcloud domain I am told “App update required”. If I “Start Update” it fails. I.e. I have no way to deactivate the app / access the nextcloud homepage (Etc.)

Could you please recommend a best next step?
Thanks in advance

Find the relevant part of the documentation for Nextcloud 15 here:

The occ console is located in the Nextcloud directory, so you need to change to that directory first before issuing the command to disable the app (change capital letters to fit your needs):

sudo -u www-data php occ app:disable NAME_OF_APP

If you don‘t know the name of the app, you can list all apps with:

sudo -u www-data php occ app:list

Thanks Jozsef,

I followed your advice and successfully disabled the app. For clarify:

  • cd -ed to nextcloud
  • yum install php-process (following message ““The posix extensions are required - see””)
  • sudo -u nginx php occ app:disable podcast

Successfully disabled, and confirmed.

Now, however authentication completely fails. The URL is <domain-name>/login?redirect_url=/apps/dashboard/. Inspecting the console, there is a “No OC found” message from JQuery, I presume. I don’t know JQuery so I’m not sure where to go from here. Any thoughts?

Worth mentioning:

  • updated all system packages
  • restarted nginx and php-fpm
  • cleared cookies.
  • Nothing is written to data/nextcloud.log when web browser auth fails.
  • Nothing is written to /var/log/nginx/error.log when web browser auth fails.


OK. I fixed the issue, although I don’t understand the cause. I’m noting it here in case anybody experiences a similar issue.

Changing the group ownership of /var/lib/php/sessions from apache to nginx allowed for successful authentication.

This post referenced changing group ownership resolving an issue with php7.4. I am unfortunately unsure which version of php I had prior to upgrading all packages. However, I upgraded packages only after the login loop became an issue, which happened only after I disabled a single application, as per Jozsef’s instruction. Why disabling an application led to the login loop, I don’t know.
