backup failing for Ubuntu 22.04 CT


May 8, 2021
Hello everyone,

I wanted to share that I've just upgraded to Proxmox 8 and successfully restored my CTs with ease. However, I encountered an issue the other day when I created a new Ubuntu 22.04 CT.

Despite setting up the environment, I faced a permissions' error while attempting to perform a backup of the CT

Interestingly, this permissions' error seems to be specific to this particular CT only. I've documented the error logs, which can be found here:

I can see the permission error, however backing up any other CT succeeds without any issues at the same storage location

If anyone has encountered a similar problem or has insights into resolving this issue, I'd greatly appreciate your input.
