Ubuntu makes its final release in 6 days (as of this post, October 23, 2009).
I think I, in my personal opinion, can call it “pretty much stable”.
Still, in this currently release (working off of nightly builds), I had a problem installing Ubuntu 9.10 on a newer Dell, due to the network configuration — the base OS worked and I am sure that the final release of 9.10 will fix the driver issue. (The disc I installed off was not the final release disc).
It seems the Ubuntu team has been avidly working out all of the various bugs, and the issues with Empathy crashing constantly on many systems has also been largely resolved. The beta of Ubuntu 8.10 was not this stable at its actual release, and I see quite an improvement over the last builds.
I think most people (even newbies) will be safe installing Ubuntu 9.10 BETA before it’s actual release, without any problems. This brings an end to our stability outlook series. Thank you for sticking with us. As always, you can subscribe to us via. RSS (click the RSS button in your address bar).
