Help total n0000000bie with Linux distro selecting for Intel compute stick.

As the headline titles.... Please. Help. I'm total n0000000bie with Linux.

I need advices for distro selecting.

We got Intel compute stick with ubuntu 14.04 LTS and it tried to update and obviesly it was not succesful. After this disasterous failure of update, the stick wont go online, not with anything we tried.

Soo i think that the best option is to install the os again.

And the point is, i realised that ubuntu 14.04 LTS is not supported anymore, with what distro we should replace it?

p.s sorry any grammar errors, english is not my first language.
