[SOLVED] Issue installing PXVE4.2 from cli

[auser]

Hello all.

I have previous experience succeeding upgrading Debian to PXVE4 from CLI

Today when attempting this on a remote host I find conflict with firmware.

I already saw: http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Jessie

and did:
'apt-get install proxmox-ve ntp ssh postfix ksm-control-daemon open-iscsi systemd-sysv'

which all worked except for pve-firmware conflict with firmware-ti-connectivity 0.43

I tried:

root@debian8:~/apt# apt-get install pve-firmware | tee apt-get_install_pve-firmware1

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
proxmox-ve : Depends: pve-firmware but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

root@debian8:~/apt#

Can anyone suggest how I can proceed?

[edit:] SOLUTION:
fix the package for firmware refusing to install with:

root@debian8:~/apt# dpkg --purge firmware-ti-connectivity

and then package installs completed, but pve-cluster config failed:

Answer re-edit /etc/hosts again so that $hostname did resolve to $EXTERNAL_IP
