I have the 32-bit Ubuntu 14.04 LTS and I am wondering if I could upgrade to 15 or 16 from the terminal. I tried to open the update manager through the GUI but it did not open.

I already entered the commands sudo apt-get update and sudo apt-get upgrade.

  • Have you tried running update-manager from the terminal to see why it won't launch – Ryan Doherty May 25 '16 at 16:08
  • I just did and it had me restart for the updates I downloaded. This is very interesting. – JmSketch May 25 '16 at 16:15

The following terminal command will update your Ubuntu version to the next available release. Press CTRL+ALT+T to open a terminal window or use the Unity application browser and search for "Terminal".

sudo apt-get dist-upgrade  #Upgrade to newest version
do-release-upgrade         #Alias of above
do-release-upgrade -d      #Upgrade to the newest development version

I actually had to change some settings before I was able to upgrade. What I had to do was go into system settings>>software and updates>>updates tab. Then I set the parameter for notifications of a new version of ubuntu to "for any release". Then I was able to use the software updater to check for new versions. I am now upgrading to 15.10.
