Error: Upgrade Ubuntu Desktop from 12.10 to 13.04 | Linux

Hello All,

Just Today I have tried to Upgrade Ubuntu Desktop Edition from Ubuntu 12.10 (Quantal Quetzal) to Ubuntu 13.04 (Raring Ringtail) and Receiving Following Error :-

Checking for a new Ubuntu release
Traceback (most recent call last):
 File "/usr/bin/do-release-upgrade", line 145, in <module>
 fetcher.run_options += ["--mode=%s" % options.mode,
AttributeError: type object 'DistUpgradeFetcherCore' has no attribute 'run_options'

Above Displayed Error is nothing but basic, I Just shared it because Many of view miss the Procedure some times even if you know the Procedure (Like Me).

This is nothing but this gives you error only because you have not updated your repository and not contacted to Ubuntu Repositories and Directory executed command to upgrade Ubuntu. 


To Update from Ubuntu 12.10 (Quantal Quetzal) to Ubuntu 13.04 (Raring Ringtail) :-

1. First Command :-

ubuntu@tejasbarot-1201HA:~# sudo apt-get update

2. Second Command :-

ubuntu@tejasbarot-1201HA:~# sudo apt-get upgrade

3. Third and Final Command :-

ubuntu@tejasbarot-1201HA:~# sudo do-release-upgrade

Make Sure your Internet Connection is Working Fine, else you will not able to perform Upgrade

Hope this helps you All.
