[SOLVED] ifupdown2 error

[Esben Viborg]

Hi

I just installed a new Proxmox node with version 6.1.2, and i am trying to use the "apply configuration" button in the network settings.
I installed ifupdown2 to do so.

However when i try to apply the config i get the following message:

incompatible 'ifupdown2' package version '1.2.5-1+pvetest1'! Did you installed from Proxmox repositories? (500)

(i am using the nosubscription repository)

check your repo, and update, the version you mention is no from the Proxmox VE no-subscription repo, see:

http://download.proxmox.com/debian/pve/dists/buster/pve-no-subscription/binary-amd64/

Thanks alot. I some got a hold of the old "stretch" repository. changing to "buster" helped.

Actually, I'm still a little confused by this issue.

I am running PVE 6.1-7, and /etc/apt/sources.list reports the following 'buster' repositories:

deb http://ftp.us.debian.org/debian buster main contrib

deb http://ftp.us.debian.org/debian buster-updates main contrib

deb http://download.proxmox.com/debian/pve buster pve-no-subscription

# security updates
deb http://security.debian.org buster/updates main contrib

yet i am still getting the error:

incompatible 'ifupdown2' package version '1.2.5-1+pvetest1'! Did you installed from Proxmox repositories? (500)

would anyone kindly let me know what i am missing?

as you can see at http://download.proxmox.com/debian/pve/dists/buster/pve-no-subscription/binary-amd64/ , that version is not available in our Buster repo.. does apt update print any messages that point to an issue? did you upgrade after fixing your repository settings?

I had the same issue. This is the first result on Google. This is what fixed it for me.
As expected, I added the the proxmox no subscription repo to sources.list
I installed ifupdown2 with

apt install ifupdown2

This installed version 3.1.0-1+pmx3
The SDN plugin complains that this is an incompatible version of ifupdown2.
According to this patch, the version of ifupdown2 must contain the string pve
So to fix,
1. List the versions of ifupdown2 in the repos

apt-cache policy ifupdown2

2. Install a specific version with pve in the version string

apt install ifupdown2=3.0.0-1+pve6

3. Click the "Apply" button in the SDN gui

you need to upgrade other packages too
