One more fails with installing Proxmox on Debian 11

[Mattias Hedman]

First up, yes I have read and followed the guide: https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye
Secondly I have checked that my /etc/hosts is correct, tested with hostname --ip-address and got the same ip-number.
I can dig my domain name to my internal DNS and do a reverse lookup.

127.0.0.1       localhost
10.1.1.100      pve2            pve2.domain.io    pvelocalhost

# hostname --ip-address
10.1.1.100

I do have the PVE kernel installed:

root@pve2:/home/admin# uname -r
5.15.53-1-pve

I have checked that the sources.list and it checks out and gives no errors the I do a apt update.

Still... when I try to
apt install proxmox-ve postfix open-iscsi

It fails:

How big is your system disk (size?)?

How big is your system disk (size?)?

The systemdisk has 210 Gb left out of 227 Gb in total.

So after a few tries and reading the wiki again, the trick was to choose "No configuration" when I was prompted to choose what kind of mail service to use. The guide says Local only that did not work.

Got the same issue setting it up as "No configuration" or "Local only" does not work.

Solution - Network had to be set to static IP rather than DHCP

auto lo
iface lo inet loopback

iface enp38s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.0.53/24
        gateway 192.168.0.1
