Upgrading Ubuntu from one version to the next is extremely easy. But before we begin we should prepare our system, so that we can have a smooth transition of our system. Some simple rules are:
- Check for the regular system updates and if there are any, install them
- Have at least 5GB of free space
- Disable any 3party PPA you have installed
- If you use the Gnome Ubuntu PPA, consider downgrading the Gnome version with the purge-ppa tool that is available in the repositories
- Make a cup of coffee and prepare to stare your PC screen for at least 45′-60′ minutes
If you didn’t use any external PPA’s and you have been using the packages provided by the official repos, you will have a smooth transition.
