[SOLVED] Cannot use LXC recovered from source - all files belong to nobody.nogroup

I had faced a disaster affecting the root partition of Proxmox VE.
Of course I have no backup, shame on me.
However, I have stored and KVM virtual disk (qcow2) and any LXC virtual disk (raw) on a seperate drive (SSD) that is not affected by the disaster.

So, I managed to install Proxmox VE 6.3 on a new disk, and now I'm rebuilding every KVM and LXC instance.
I was successfull with a KVM instance running Win10 and 2 LXC instances.

But now I'm failing with another LXC instance hosting a mailserver application (mailcow).

What did I do in order to recover the virtual instances?
1. Creating a new CT using LVM (not LVM thin)
2. Configuring storage to use my working SSD
3. Migrate the newly build virtual disk from LVM to SSD
4. Copy the old raw file over the newly created virtual disk raw file
5. Start LXC

As said, this procedure worked with 2 LXC instances, and now it fails with another LXC instance.
The error message when entering the started LXC instance is:
$ pct enter 104
bash: /root/.bashrc: Permission denied

Furthermore I have identified that any directory has owner nobody.nogroup.

drwxr-xr-x+  4 nobody nogroup 4096 Jul 13  2016 www

The ownership must be root.root instead.

Can you please advise how to fix this issue?
