I am a new user here and I wanted to know if I could update from Ubuntu 14.04 to later versions without reinstalling Ubuntu to my system?

Edit /etc/update-manager/release-upgrades and change:

[DEFAULT]
Prompt=lts

to:

[DEFAULT]
Prompt=normal

and then:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

and finally:

do-release-upgrade

If it tells you command not found for do-release-upgrade, install it with:

sudo apt-get install update-manager-core
nixpower

  • FYI do-release-upgrade does not require sudo, it will make its own call to sudo. The steps prior to running do-release-upgrade in this answer usually aren't required, but this answer is comprehensive enough to cover all bases. – thomasrutter Jul 02 '15 at 02:54
  • @thomasrutter I'm not running Ubuntu, so I wouldn't know if do-release-upgrade needs sudo, but thank you, I will edit it! They probably aren't required, spare the change to the release-upgrades file, but it's better to provide as much as possible in my answer. – nixpower Jul 02 '15 at 12:12
