[Bug 1079335] Re: Upgrade from Natty to Oneiric fails with extras repository activated

[sampo555]

** Description changed:

+ The upgrade from Natty to Oneiric fails if the extras repository is
+ activated as Natty has been removed from extras.ubuntu.com and APT hits
+ 404 when it tries to update the package information. In consequence
+ Distribution Upgrader aborts the entire upgrade although the error
+ doesn't really compromise the upgrade process.
+ 
+ [Workaround]
+ 
+ Disable extras repository:
+ 1) Open Software Sources
+ 2) Go to 'Other Software' tab
+ 3) Uncheck both checkboxes for "Independent"
+ 
+ Then restart the upgrade.
