How to upgrade from 3.8 to 4.4

[fluffyMart]

I'm 99% sure I got this OS from linuxlite.com. I then burnt it to a DVD and installed on here as dual-boot with Windoze.

Her'e s the output you requested...

[tt]martin@Latitude-E5500:~$ cat /etc/llver
Linux Lite 3.8
martin@Latitude-E5500:~$ apt policy lite-upgrade-series3
lite-upgrade-series3:
  Installed: 2.0-0120-linuxlite
  Candidate: 2.0-0120-linuxlite
  Version table:
*** 2.0-0120-linuxlite 500
        500 http://repo.linuxliteos.com/linuxlite citrine/main i386 Packages
