Solve GPG error of ppa.launchpad.net
Perhaps you've received a warning like this once, executing the command sudo apt-get update:
Reading package lists... Done
W: GPG error: http://ppa.launchpad.net intrepid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY ...
W: You may want to run apt-get update to correct these problems
To solve this problem, you'll only have to execute the following line in your command shell, replacing the word "intrepid" by the name of your current Ubuntu version (e.g. "jaunty").
wget http://ubuntu-blog.com/wp-content/uploads/scripts/launchpad-update && sudo chmod +x launchpad-update && sudo ./launchpad-update intrepid
The command above will realize three actions, first it'll download a script from the ubuntu-blog servers, then it'll give the permissions to execute it and finally it'll run the downloaded script.
Once the command is executet, after a few seconds you'll be receiving an output like this one:
Release: intrepid
Please Wait...
OK

I updated the script to include karmic, and I had to leave it to run overnight, but unfortunately it didn’t work. I still get the errors. Never mind, thanks though.

I’m behind a firewall (though I have http_proxy and https_proxy exported) so perhaps that’s an issue. No errors from the script though.
