I'll be updating tonight 
I've been running 2.6 beta on 1 system for about a week and 2.2 on another system for close to a year.
Great OS!!
On a side note...
I'm still new-ish to Linux and not sure if this was something in Beta or not, I haven't attempted to reproduce in 2.2, but... Last night I was messing with the wireless (typically this box is wired) and Unchecked the "Enable Wireless" option of the network manager. Since then the option to enable has gone away completely (Its not a laptop, FN+F2 isn't an option).
- It may be me but...
After my trip to Austin Texas ans my Linux-Lite laptop wireless failed to connect to my sons wireless router.
Let alone not even see it.
When I got home I installed WICD which is easier for me to trouble shoot and use. YMMV from mine though.
$ apt-cache policy wicd
wicd:
Installed: 1.7.2.4-4.1ubuntu1
Candidate: 1.7.2.4-4.1ubuntu1
Version table:
*** 1.7.2.4-4.1ubuntu1 0
500 http://us.archive.ubuntu.com/ubuntu/ trusty/universe i386 Packages
100 /var/lib/dpkg/status
my trouble shooter is
netstat
Not sure if a update killed network manager for me. I tried re-installing and looking through /etc/resolv.conf.
It was just easier to install WICD and call it a day for me.
Thanks for the info, I may look into if still problems..
Think I updated from Beta to Final!!! Quick and Easy
Missing "Enable Wi-Fi" (Yes has a Wi-Fi usb; was seen prior to unchecking see next image)

What it looked like prior.

- I can move to another thread, not wanting to hijack
TIA
EDIT:
*I updated the Dell Mini from LL2.2 to 2.6 smooth as glass. KUDO's
** Figured out the Wi-Fi problem, looks like I blacklisted it...
