I am running an ISPConfig3 server with Lenny which I want to upgrade the Squeeze, however... I am not at the terminal and the server is in my server-hall.

Can I upgrade Lenny to Squeeze over SSH? I checked the update list and both openssh-client & openssh-server are being kept back... however, I feel unsure to if I can and should proceed.

This is what apt-get shows me when running apt-get upgrade:

Can I do the upgrade? Is there anything then will kill my SSH connection? Can I run it otherwise in the background so the upgrade process continues even-though the SSH connect might have been killed?

That's why God invented the KVM over IP.

In my experience, I wouldn't do it if it's not absolutely necessary. If you can wait and do it after the weekend, I wouldn't take the risk.

I've done multiple lenny to squeeze upgrades and in about 30 machines, I had only one that didn't turn out well. So it's for you to decide if you can take the risk or not. Normally these upgrades go smoothly. Do note that you will need to reboot the machine to complete the upgrade, so you will loose ssh connection anyway.

Normally you will not loose SSH when doing a dist-upgrade from lenny to squeeze.

  • I guess because of the kernel upgrade. Its running on a healthy Dell Poweredge 1920, so hardware wise it shouldn't be a problem. But does that happen last... loosing the SSH connection that is. Jun 16, 2012 at 22:30
  • I'll start off with an apt-get update before doing an dist-upgrade. Jun 16, 2012 at 22:35
  • Update just downloads the list of updates,upgrade will install them. Jun 16, 2012 at 22:52
  • Sorry, meant upgrade, not update. I ran upgrade and am now running dist-upgrade keeping back openssh-server and openssh-client Jun 16, 2012 at 22:53
