You may want to create your own Virtual Infrastructure

I Prefer to use NANO instead of VI/VIM and also i usally use direct root rights instead of sudo command

1) Check & Modifiy your Host-File

# sudo nano /etc/hosts
You may have to check, that you have 127.0.0.1 added to your hosts-file
You may also have to check that your Server-IP (1.2.3.4) will replaced by the real IP and the real hostname


127.0.0.1 localhost.localdomain localhost
1.2.3.4 myservername-short myservername.mydomain.tld

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

2) Check & Modify your apt source.list

# sudo nano /etc/apt/source.list
Copy and Paste


deb http://ftp.at.debian.org/debian wheezy main contrib
# PVE repository provided by proxmox.com, only for installation (this repo will stay on 3.1)
deb http://download.proxmox.com/debian wheezy pve
# security updates
deb http://security.debian.org/ wheezy/updates main contrib

2.1) Add a key to apt-key

# wget -O- „http://download.proxmox.com/debian/key.asc“ | apt-key add –
