Upgrading Ubuntu Server to 11.10 using SSH

This entry was posted by on Friday, 28 October, 2011 at

About half a year ago I wrote about Upgrading Ubuntu 10.04 using SSH. I did the same thing when 11.10 (Oneiric Ocelot) was released. And with great success!

Update: I did the upgrade to 12.04 using SSH and so far nothing to report to warrant a dedicated article.

Actually, it was rather boring: I SSH to my NAS, sudo do-release-upgrade and that was really all there was to it. The secondary SSH server is started on port 2011 just in case something goes wrong and you need to get into your box.

It downloads the new packages, took about three minutes.
Then there’s some config file questions – I usually keep using my own modified config files, don’t feel like making the modifications again.

Then it prompts if it should reboot. Of course we want to reboot and load the new kernel! So it’s time to keep the fingers crossed when the system reboots and the SSH session terminates, and in a few minutes we’re able to login again.

So far the only real change I notice is that powertop got a once-over. It is more interactive now and you can toggle performance tweaks in stead of powertop prompting you with suggestions. It gives some more insight and I’m looking forward to seeing if this kernel (the first 3.0 I run on this box) is yet again more energy efficient (like the last one was).

Other than that, it just works – and that’s the way it should be.
