Need some help. Should I attempt this over SSH?
"Welcome to Ubuntu 15.10 (GNU/Linux 4.2.0-42-generic x86_64)
Your Ubuntu release is not supported anymore.
For upgrade information, please visit:
http://www.ubuntu.com/releaseendoflife
New release ‘16.04.2 LTS’ available.
Run ‘do-release-upgrade’ to upgrade to it."
Best option is to do this directly on the device. It is possible ssh is getting updated and the connection will drop. I am unsure if there is a machanism in ubuntu to prevent this…
I’ll just wait for ROCK. This is a completely headless machine.
Headless should/does not mean you can’t SSH or connect to it via a terminal when needed.
There’s no pressing reason to upgrade, so no reason to invite the tiny risk of trouble. Ubuntu 16.04 is not going to make anything materially better for you in a headless application like this.
As far as headless/ssh goes, ubuntu opens up a second sshd on an alternate port that is meant to survive even in the rare case that something goes wrong with the update and you lose the “main” sshd. I’ve never needed to use this (and I’ve updated dozens of machines without a head over the years, often hundreds of miles away in a data center someplace).
Thanks. That was the answer I assumed, but needed confirmed. Now if someone could help me re my posts about RoonBridge dropping 100% of the time.
