contabo VPS : Proxmox installtion on debian 12 -

[yboujraf]

Dear

We try to install proxmox on Contabo vps (debian 12).

We followed the steps as described here : https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm

When running this command :

Install the Proxmox VE packages

> apt install proxmox-ve postfix open-iscsi chrony

We get this error :

dpkg: error processing package proxmox-ve (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
ifupdown2
pve-manager
proxmox-ve

If anybody has or had the same issue thanks for sharing ;-)

Best Regards
Youssef

Looks as expected. Interestingly you already have the pve kernel installed which indicates you ran the installation the second time in your first post correct?

Okay let's try the following:

First let's manually try installing ifupdown2:

apt install ifupdown2

Second, let's see if we can get a bit more output about what is failing:

dpkg --configure -a

Can you please also check if this reports the correct IP?

hostname --ip-address
AA.ZZ.XX.YY # should return your IP address here

Dear,

Thanks for your quick replies and I appreciate it.

Finally to install, the hosts file needs to reference the ip address of the host.
But unfortunately, each time to reboot the ip address becomes 127.0.1.1 ;-)

To fix that, I edited : "/etc/cloud/templates/hosts.debian.tmpl" and forced to : "my_ip_address {{fqdn}} {{hostname}}"
Rebooted and then the install is complete and I have access to proxmox.

Now, I am expecting to add my secondary public ip and /etc/network/interfaces is :

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

don't know where the config is ?

Best Regards
Youssef

Okay, this makes things a bit more complicated if your hosting company re-configures your VM. I assume you are aware that you are effectively setting yourself up for nested virtualization in this environment after all?

For further assistance I think we should directly get in touch as this seems to be a bit too much for this forums context

Dear @Bent

Today, I have my own proxmox with enterprise license on bare metal servers.

I was looking to evaluate the easiest way to migrate our on premise proxmox to the cloud and unfortunately if you are using VPS instead of physical server in the cloud, it failed.

While we're being pitched the idea of migrating to the cloud.

If you have more experience than me using proxmox pve with pFsense/OPNsense, K8S cluster than we could have a chat.

Thanks for your reply then how to reach you ?
