Problem with upgrade Nextcloud 27.0.2 to 27.1.0

Today I tried to update my Nextcloud instance, but there was an issue.

I decided to run updates from the command line. Console immediately displays an error, so I decided to delete the file with the config copy.

I removed old config file

After this operation, the update went correctly and I selected “yes” for occ upgrade

After the entire upgrade process, I disabled maintenance mode.
