Hi,

I am getting problem while upgrading my software repository which cause problems in many other updation of the system.

Error :

W: GPG error: http://ppa.launchpad.net karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6B15AB91951DC1E2

W: GPG error: http://ppa.launchpad.net karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EF4186FE247510BE


Also I have search and applies all possible solution which is available while copying this error to google, but none of solution is working.

Please find screen shot for the same, and let me know the possible solution to get rid from this issue.


Regards,
Anurag

Does this work?



gpg --keyserver keyserver.ubuntu.com --recv-keys EF4186FE247510BE 6B15AB91951DC1E2 && gpg --export --armor EF4186FE247510BE 6B15AB91951DC1E2 | sudo apt-key add -

Is http://ppa.launchpad.net (http://ppa.launchpad.net/) even a valid Ubuntu repository? Forgive me if this is a stupid question.
edit: I couldn't find anything like /ubuntu, /karmic or /pub on that site, though I did see what looked like a repo in one of the subdirectories. If you can expect apt to work for *any* subdir, then that is a new/cool feature for me.
