While trying to update my nextcloud install from 12.02 to 12.03, the web updater displays the following:
Current version is 12.0.2.
Update to Nextcloud 12.0.3 available. (channel: “stable”)
Following file will be downloaded automatically: https://download.nextcloud.com/server/releases/nextcloud-12.0.3.zip
Check for expected files
Check for write permissions
Enable maintenance mode
Could not copy “/var/www/nextcloud/config/config.old” to “/var/www/nextcloud-data//updater-oc7ocyzpooo6/backups/nextcloud-126.96.36.199/config/config.old”
The TWO // in the error line is not a type. That is what the error message says.
My server is Ubuntu 16.04 LTS SERVER running in an ESXi 6.5 VM.
I’ve set maintenance mode back to false in the config.php, updated the OS, rebooted, and I still get the error. This was initially a 10.x install that has been updated multiple times, without a single error.
