I’m not sure how I let late October pass by without upgrading my Linux server! Ubuntu 15.10 (Wily Werewolf) was released back on October 22 and somehow (still not sure how) I completely missed it. So today I did the first ‘do-release-upgrade’ on the NUC (since I clean installed Vivid back in July). This one was pretty smooth, not a problem to speak of!
So now I’m good until April 2016, when Xenial Xerus will come out.
