Server: Manual upgrade with occ command from 13.0.6 to 14.0.3 throws unhandled exception

[lentidas]

Steps to reproduce

1. Perform manual upgrade from 13.0.6 to 14.0.3 using sudo -u www-data php /var/www/nextcloud/occ upgrade

Expected behaviour

Upgrade should run and complete (this has been my upgrade method for the past year without any issue!).

Actual behaviour

occ command throws an unhandled exception

An unhandled exception has been thrown:

Tried updating from 13.0.6 to 13.0.7 using the same method and that was successful. I will try to update to version 14.0.3 from 13.0.7 to see if that will work.

Let' close this for now. We can reopen it if this happens again.

Could you please reopen this issue?

Only this weekend I had another chance to try upgrading my server and the error persists when upgrading from 13.0.x to 14.0.x. Every log and setting is the same.

For what it's worth, upgrading from 13.0.7 to 13.0.8 went smoothly! The problem only happens with versions >= 14.0.0.

To complement the information above, my upgrade routine is based on Nextcloud documentation and is the following:

service apache2 stop

rm -Rv /root/nextcloud/backups/nextcloud-*
cd /root/nextcloud/backups && rsync -Aaxv /var/www/nextcloud/ /root/nextcloud/backups/nextcloud-dirbkp_`date +"%Y%m%d"`/ && mysqldump --single-transaction -h localhost -u nextcloud -p[password] nextclouddb > nextcloud-sqlbkp_`date +"%Y%m%d"`.bak && history -c

cd /root/nextcloud/downloads && wget https://download.nextcloud.com/server/releases/nextcloud-X.X.X.zip

unzip nextcloud-X.X.X.zip

rm -Rv /var/www/nextcloud-old && mv -v /var/www/nextcloud /var/www/nextcloud-old

mv -v /root/nextcloud/downloads/nextcloud /var/www

cp /var/www/nextcloud-old/config/config.php /var/www/nextcloud/config/config.php

cp -Rv /var/www/nextcloud-old/apps /var/www/nextcloud/

chown www-data:www-data /var/www/nextcloud/ -R

service apache2 start && sudo -u www-data php /var/www/nextcloud/occ upgrade

[sebastian-orlowski]

I get exactly the same stacktrace while upgrading from Nextcloud 13.0.8 to either 14.0.0 or 14.0.4 with the official docker image of Nextcloud, enhanced by some modifications to run cron as recommended in the Nextcloud documentation.

I also tried disabling all apps before calling "occ upgrade" using "sudo -u www-data ./occ app:disable", but this command triggered the same error and stacktrace.

Update: By deactivating the theming app in the old instance before shutting it down and starting the upgrade, the database conversion worked without problems for me. I simply re-activated the theming app afterwards, and everything was fine.

[MorrisJobke]

cp -Rv /var/www/nextcloud-old/apps /var/www/nextcloud/

You copied over the old apps. You only should copy over non-shipped apps and not all apps. That is the reason for this breakage. The theming app is shipped inside the release under apps/theming and needs to be as of the version in the release tar ball. This is also the reason why we recommend to user the built-in updater - it takes care of all of those tiny steps.

See https://docs.nextcloud.com/server/stable/admin_manual/maintenance/update.html for more details.
