Upgrade to a New Version

  • This is for a server edition, so for desktop edition, better use Update Manager in GNOME.
  • Install update-manager-core 
$ sudo apt-get install update-manager-core
  • Use do-release-upgrade to upgrade. 
$ sudo do-release-upgrade
  • If the current version is a Long Term Support (LTS) version yet it needs to be upgraded to a normal version, open the file below. 
/etc/update-manager/release-upgrades
  • Edit the following line 
Prompt=lts
  • To this 
Prompt=normal

Problems

If upgrading from the LTS to another LTS doesn't work with the following error message. 

$ do-release-upgrade 
Checking for a new ubuntu release
No new release found

Try this 

$ do-release-upgrade -d
