Hi all,
Lately I updated Dietpi to v7.8.2 . Nextcloud goes to maintenance mode for upgrading
After pressing start update it gives error
Then it goes to maintenance mode . I tried this command
occ upgrade
I it’s done without error but nothing changes . I tried this command :
root@DietPi:/# ncc maintenance:mode --off
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
Maintenance mode disabled
Same thing nothing happen . Can anyone help me please ?

Maintenance mode disabled
Maintenance mode is disabled
but still same problem 
are you able to access web site?
Yes but it shows the same page in the first post . I can not access my files .
hm not sure what the issue could be. Strange is that your system is recognising an update but it is the same version as installed
Current version is 21.0.7.
Update to Nextcloud 21.0.7
MichaIng
maybe you would have an idea
Thank you Joulinar . I was able to solve the problem
I just went to " /var/www/nextcloud/apps" and delete folder " duplicatefinder " , restart the services and update . And It works !
Thank you gain 
ah not sure why I have overlooked it before. Indeed an issue with duplicatefinder as it tried to allocate more memory then allowed.

For the future, you can increase the maximum allowed memory allocation (adjust the PHP version string in case):
echo -e '; Personal PHP overrides\n; priority=99\nmemory_limit=1G' > /etc/php/7.3/mods-available/custom.ini
phpenmod custom
However, that an app requires that much for an upgrade is indeed unexpected. Nextcloud recommends 512 MiB, so this is what we apply on install (the PHP default is 128 MiB). Probably something to report to the app maintainer, to allow using it as well on devices with less RAM available.
