Go to Software Center > Edit > Software Sources and select the Main Server.

Regarding the error with Launchpad PPA authentication, Software > Center > Edit > Software Sources > Other Software Tab and disable the offensive Launchpad ppa for the moment.

And then,

sudo apt-get update

[raju50]

I did just that. I disabled four repositories where it was written ppa.launchpad.net and then also did sudo apt-get update. And then once again I clicked Check button in Update Manager and this time I got the following error:

Post the output of this command.

cat /etc/apt/sources.list

While posting, press the # icon in post menu and paste your text in between the generated code tags

It looks like something is wrong with that mirror. I can only see dapper drake there: http://ubuntu.mirror.cambrium.nl/ubuntu/dists/

The official mirror site also says it's last known update time is unknown: https://launchpad.net/ubuntu/+archivemirrors

Try changing your software sources to point to one of the up to date mirrors listed in the above link (preferably one close to home).

sources.list seems ok.

Did you follow this step from my first post?

Go to Software Center > Edit > Software Sources and select the Main Server.

[raju50]

Yes. Canonical-supported Open Source software(main) is already tick marked.

[mcduck]

I don't think he's asking you to enable the "main" repository, but to change the server to Ubuntu's main server. Or, really, anything else than the mirror you are now using.

(It's the "Download From"-dropbox on the Ubuntu Software-tab)

[raju50]

Yes I did that. Thanks. Now I'm not getting any error.
