unable to restore an privileged CT as unprivileged 2026

there is another thread named 'unable to restore an unprivileged CT as unprivileged' ( https://forum.proxmox.com/threads/unable-to-restore-an-unprivileged-ct-as-unprivileged.80004/ ) .

so I have a privileged container I want to convert to unprivileged.

tried these:

Code:

# pct restore 181 /media/pbs-nfs/dump/vzdump-lxc-102-2026_06_20-17_00_09.tar.zst -ignore-unpack-errors 1 -unprivileged --storage nvme-4tb

merging backed-up and given configuration..

and

Code:

:# pct restore 182  /media/pbs-nfs/dump/vzdump-lxc-102-2026_06_20-17_00_09.tar.zst  --unprivileged  1 --storage nvme-4tb

merging backed-up and given configuration..

in both cases the .conf file showed unprivileged

Code:

:# cat /etc/pve/lxc/182.conf
arch: amd64
cores: 2
features: nesting=1
hostname: squid-deb-proxy
memory: 4096
mp0: /mnt/fbc,mp=/mnt/fbc
nameserver: 10.1.3.41
net0: name=eth0,bridge=vmbr3,firewall=1,hwaddr=BC:24:11:1D:1D:44,ip=dhcp,tag=3,type=veth
ostype: ubuntu
rootfs: nvme-4tb:vm-182-disk-0,size=16G
searchdomain: test.com
swap: 512
unprivileged: 1

for us this is not an urgent issue to be fixed. If anyone has a suggestion to try reply and I'll test.

Hi @RobFantini

thanks for posting on the forum!

I currently don't see an issue in these restores. Could you please elaborate on what your expected behavior would be or what errors you see?

Yours sincerely
Jonas
