[Solved] Upgrade 12.0.4 to 12.0.5 - Could not copy

I am trying to update nextcloud 12.0.4 to 12.0.5. It failed at the Create backup step with could not copy. Every time I try it is a different file. For example,

“Create backup
Could not copy “/var/www/nextcloud/apps/systemtags/l10n/es_PA.js” to “/mnt/data/updater-ocbxwplwqcy5/backups/nextcloud-12.0.4.3/apps/systemtags/l10n/es_PA.js””

I can’t seem to figure it out for the life of me. Everything is owned by www-data and I haven’t had this issue before. I am running Ubuntu Server 16.04 with the TechandMe VM. The data folder is shared from Windows 2012 R2. I gave the user full control of the backup directory and that didn’t help.

Any ideas? Spending way too much time for a minor update.

Thanks for the help.

I still haven’t been able to figure this out. The other similar posts didn’t seem to help.

Finally got it to work but using the TechandMe upgrade script. Which basically does a back up and manual upgrade. Which I haven’t had to do before.
