Steps to replicate it:

  2. Forget about that and click the button to continue the update the next day
  3. Get an error in the browser updater
  4. Get this error on the command line

The output of your Apache/nginx/system log in /var/log/____:
The log file in the settings does not exist. ?

It looks like there is some version mismatch in symfony.

try to disable recognize - if installed - and start the upgrade again

I followed the instructions at Upgrade manually — Nextcloud latest Administration Manual latest documentation and managed to fix it by running:

sudo -u www-data php occ maintenance:repair
sudo -u www-data php occ upgrade

@ralfi thank you for your reply, I do have recognize installed but I didn’t end up disabling it.
