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.
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.
