What is the simplest way for me to upgrade from Quantal to Saucy?
What I tried:
$ sudo do-release-upgrade
What it returned:
Checking for a new Ubuntu release Get:1 Upgrade tool signature [198 B]
Get:2 Upgrade tool [1,135 kB]
Fetched 1,135 kB in 0s (0 B/s)
authenticate 'saucy.tar.gz' against 'saucy.tar.gz.gpg' extracting 'saucy.tar.gz'
Checking package manager
Can not upgrade
An upgrade from 'quantal' to 'saucy' is not supported with this tool.
