ubuntu gets updated but indicates "package list not updated"

[sugavaneshb]

Mine is Ubuntu 11.04 desktop edition...When i open the update manager to update the system and press check... it checks for and downloads or updates or whatever a list and shows a list of packages to download... I accept them and the system downloads,installs and restarts....... Now when I open the update manager again,it says,

"The package info. was updated 26 days ago... There might be software updates available for this system..."

So i press the check button again... It shows up an error "check your internet connection" with details showing up.......

"W:GPG error: http://ppa.launchpad.net natty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2CC98497A1231595, W:Failed to fetch http://ppa.launchpad.net/sugavaneshb/ppa/ubuntu/dists/natty/main/source/Sources 404 Not Found
, W:Failed to fetch http://ppa.launchpad.net/sugavaneshb/ppa/ubuntu/dists/natty/main/binary-i386/Packages 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead."....


And there are no packages list showed up to be downloaded.... What am i supposed to do now? Is the system really updated? Are there any broken packages...??! Help me out.....

You have a non-valid PPA in your Software Sources list.

Open the Repositories Tab in Synaptic Package Manager and un-tick the PPA
http://ppa.launchpad.net/sugavaneshb...source/Sources

Then Reload and see if you still get the same error.

Good Luck

Thanx... I suppose it solved half of the problem i suppose... But now still i get this error when i try to reload...

"W: GPG error: http://ppa.launchpad.net natty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2CC98497A1231595"

....When the PPA is not included at all there is no error... so should i remove ppa completely from souces...i mean untick...

If it is a valid PPA,you can run
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2CC98497A1231595 to add the key.

If it isn't a valid PPA ,you can delete it from Software Sources.

Good Luck
