Hello Linux Geeksters.
In this article I will show you how to upgrade / update from Ubuntu 13.04 Raring Ringtail to Ubuntu 13.10 Sauchy Salamander.
This is what you have to do:
$ sudo sed -i 's/raring/saucy/' /etc/apt/sources.list
$ sudo apt-get update && sudo apt-get dist-upgrade
Or:
$ sudo update-manager -d
-d upgrades to the newest development release.
At the moment, this is highly not recommended, since not even an alpha version of Ubuntu 13.10 was not released yet.
Or plainly:
$ update-manager -d
Wait for it to finish, and click “Upgrade.”
getting an error in terminal after all file are downloaded..
