I get the following error trying to restore a Container.

How can i get more information what the error is / how to solve it?

KVM restore is working, LXC fails, Verify finds no errors on backup

Have exactly the same problem

@proxmox-devs, any insights what is happening here?

Apologies for not being a dev, but did you or can you run a verify job on the backup that you are trying to restore?

I already did that, no problems.
I have created a new container, mounted the backup and manualy copied the files, but it is worrying that it does not show why the restore is not working
