How to upgrade Ubuntu version
New Ubuntu version is released every 6 months and by default Ubuntu is configured to allow you to upgrade to the new version. This is also true for other Ubuntu derivatives such as Kubuntu or Xubuntu.
Ubuntu can be upgraded to the lastest version using do-release-upgrade tool from the terminal.
Steps to upgrade to latest version of Ubuntu or Kubuntu:
- Create a backup of both your system and data.
Make sure that you have a backup copy of both data and configuration of the system you're upgrading. System upgrade is not 100% reliable and could result in conflicts and a malfunctioning system.
- Launch terminal.
- Update apt's package list from repository.
