error when trying apt-get update?

[insanity99]

it updates a lot then this shows up:

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 FC66403D8670A035
W: Duplicate sources.list entry http://ppa.launchpad.net intrepid/main Packages (/var/lib/apt/lists/ppa.launchpad.net_spring_ubuntu_dists_intrepid_main_binary-amd64_Packages)
W: You may want to run apt-get update to correct these problems

getting something similar in 8.04

W: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4874D3686E80C6B7

Both of you can check for the GPG sig at wherever you have got the ppa from

insanity99 - your second error Duplicate sources.list - backup and then open the file for editing

sudo cp /etc/apt/sources.list /etc/apt/sources.list.2701
gksu gedit /etc/apt/sources.list

You should find the same line in there twice - delete one of them and save, then run

sudo apt-get update

Open a terminal (Applications -> Accessories -> Terminal)
and:

...

gpg --keyserver keyserver.ubuntu.com --recv 8670a035

gpg --export --armor 8670a035 | sudo apt-key add -

...

gpg --keyserver keyserver.ubuntu.com --recv 6e80c6b7

gpg --export --armor 6e80c6b7 | sudo apt-key add -

Both of you:

sudo apt-get update

I thought PPA's couldn't be GPG signed, or at least they couldn't when I last checked. When did this change?

[insanity99]

thanks guys seems to be resolved.

Yes. I don't know why, but this is a quiet common warning.

I've found the solution here: http://ubuntuforums.org/showthread.php?p=6616484 (post #2, thanks to taavikko)

It would be nice to write a little howto for future reference,
but I'm lazy .

As it's gone for the moment
