I attempted to add an alternate repository in Ubuntu 8.10. Can someone help out with the error message I received?
Ubuntu Intrepid
After contacting Ubuntu packagers, it seems that Jaunty packages will never enter backports. Therefore it is recommended to install Kdenlive using alternative repositories. Here is our recommended choice:
- Go to your system menu > Software sources > Third-Party Software
- Click add and paste this line in:
deb http://ppa.launchpad.net/baudm/ubuntu intrepid main - Close software source and click reload
I received the following when I reloaded:
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 B00E04A9D58062FB

I tried each command. Neither one resolved the issue. I still get the error message when I reload from the repositories. For the second command, I had to break it into two command lines to get it to complete successfully:
$ gpg --export --armor 0c713da6 | sudo apt-key add
gpg: can't open `': No such file or directory
$ gpg --export --armor 0c713da6 > test
$ sudo apt-key add test
OK
