Always unable to detect OS distribution after pct restore

[Norbert_42]

Hello,

I'm trying migrate from OpenVZ to Proxmox. I have 6 VM 32 or 64 bits. The migration of VM with
OSTEMPLATE="debian-7.0-x86" seems OK but all VM with OSTEMPLATE="debian-8.0-x86_64-minimal" or
"ubuntu-14.04-x86_64" send
Detected container architecture: amd64

What is the content of /etc/debian_version (inside the tar archive)?

 

[Norbert_42]

CTID 101 cat /etc/debian -----> 8.4
CTID 105 cat /etc/issue -----> Ubuntu 14.04.4 LTS
CTID 106 cat /etc/debian -----> 8.4

I feel your answer (nothing > 8.0 or 14.04) but how can i do with this versions. I'm used to have the latest OS versions.

 

[dietmar]

And what is the content of /etc/debian_version?

 

[Norbert_42]

On promox
proxmox:~# cat /etc/debian_version
8.4

On VM
CTID 101 cat /etc/debian_version -----> 8.4
CTID 105 cat /etc/issue -----> Ubuntu 14.04.4 LTS
CTID 106 cat /etc/debian_version -----> 8.4

 

[dietmar]

Strange, that works for me. Looking at the source code, that error message is only triggered if /etc/debian_version file does not exist.

 

[Norbert_42]

Hum, maybe can you give me the files of source code to verify?

 

[dietmar]

Hum, maybe can you give me the files of source code to verify?

[Norbert_42]

This files are identical. Should install git?

 

[Norbert_42]

I found an issue. I re install a new version with appliance Proxmox.
My first installation was unpackaged on Debian 8

The software version appears earlier

[Norbert_42]

Wrong. All problems came from ploop disk.
I found in OpenVZ forum that "the need for converting ploop disks to simfs since proxmox does not support ploop yet (not considered as stable)."
You can convert ploop to simfs with a script here. Read all comments.
