Problem in files owners with backup/restore

[proxbob]

Hi,

I have found a problem:

I have a debian LXC container, unprivelegied,
I backup it in stop mode from the web GUI,
I restaure it to another ID,
I stop the first and start the new LXC,
Now, I can't access ssh on the new LXC, I then connect to proxmox host and "pct enter ID", I get this :
-----------
root@hostname:~# pct enter XXX
bash: /root/.bashrc: Permission denied
root@lxc:~#
-----------

I think when extracting files the files owners have not been set correctly because :
-------------
root@lxc:/# ls -alh /
total 88K
drwxr-xr-x 22 nobody nogroup 4.0K Dec 22 23:06 .
drwxr-xr-x 22 nobody nogroup 4.0K Dec 22 23:06 ..
drwxr-xr-x 2 nobody nogroup 4.0K Dec 12 14:44 bin
drwxr-xr-x 2 nobody nogroup 4.0K Mar 13 2016 boot
drwxr-xr-x 3 root root 340 Dec 22 23:06 dev
drwxr-xr-x 70 nobody nogroup 4.0K Dec 22 23:06 etc
-rw-r--r-- 1 root root 0 Dec 22 23:06 fastboot
.............

I'm using the latest version with latest kernel.

Regards,

AFAIK this bug was fixed in pve-container 1.0-86 - please update and test again.

I was using pve-container: 1.0-88, now I did an apt-get update && apt-get upgrade && apt -get dist-upgrade, and did all the steps described but with the same problem.

The problem/fix was in the restore code, so you need to repeat the restore first...

 

[proxbob]

I repeated all the steps as I sayed, I deleted the new lxc AND the backup, created a new backup and restored it, the problem remain the same.

Right, I am now also able to reproduce it. Please can you open a bug at bugzilla.proxmox.com?

Done.

Hi,
is that problem fixed? I still have that problem!!! Exits a workaround to set the ownership correctly afterwards?

the only solution is to restore again with command line and -unprivileged flag.
