[Solved] 12.0.2 to 12.0.3 Update Failes at "Create Backup"

While trying to update my nextcloud install from 12.02 to 12.03, the web updater displays the following:

Initializing
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
Retry update
Check for expected files
Check for write permissions
Enable maintenance mode
Create backup
Could not copy “/var/www/nextcloud/config/config.old” to “/var/www/nextcloud-data//updater-oc7ocyzpooo6/backups/nextcloud-12.0.2.0/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.

Hi,

AFAIK datadirectory in the config file should not have a trailing slash.

Perhaps you have in the config file something like

‘datadirectory’ => ‘/var/www/nextcloud-data/’,

If so I would remove the last “/”.

Nice catch, but I"m sad to say after making that change the error message doesn’t have the double //, but it still fails.
Create backup
Could not copy “/var/www/nextcloud/config/config.old” to “/var/www/nextcloud-data/updater-oc7ocyzpooo6/backups/nextcloud-12.0.2.0/config/config.old”

Any ideas?

To ensure it wasn’t a weird permission issue, I reset perms on the nextclould-data folder with:

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

No change, still errors out.

does that path exist? especially .../nextcloud-data/... looks strange to me. maybe it should be .../nextcloud/data... instead?

Just to be sure… Is the data-directory ( in your case /var/www/netxcloud-data ) writeable?
This means you need at least a rwx------ permission. I use 750 (rwxr-x—)

So I would go with:
chmod u+rwx /var/www/nextcloud-data

Perhaps there is something useful in the nextcloud.log file: can you find share some parts of it?

Next move could be:
mkdir -p /var/www/nextcloud-data/updater-oc7ocyzpooo6/backups/nextcloud-12.0.2.0/config/
chown -R www-data:www-data /var/www/nextcloud-data/updater-oc7ocyzpooo6

The directory exists, and is writeable. I made no changes.

/var/www/nextcloud-data/updater-oc7ocyzpooo6/backups/nextcloud-12.0.2.0 is also empty.

I don’t understand… if /var/www/nextcloud-data/updater-oc7ocyzpooo6/backups/nextcloud-12.0.2.0 is empty, where the listing above came from?

Moreover I think there is a bit of confusion between the installation directory and the data directory.

Can you list the content of the installation directory, with special attention to the config directory? I suppose you have a config.old file not readable by www-data.

Sorry, I should have included /config on the path when I stated it was empty.

To clarify:

/var/www/nextcloud-data/updater-oc7ocyzpooo6/backups/nextcloud-12.0.2.0/config
1. Exists
2. Is Empty
3. Perms: drwxr-x— 2 www-data www-data

Removing the config.old fixed it. Very nice catch.

Good to know!

I’m glad we determined the exact problem, but had I ran:

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

when I ran sudo chown www-data:www-data /var/www/nextcloud-data -R (Post #4), it would have fixed it to.

A perfect example of the need to be careful with file permissions.
