No pubkey error....HELP!!!

[joemartin]

Update Manager always gives the following error message. Any help would be greatly appreciated to Ubuntu 8.1 newbie....


W: GPG error: Index of / intrepid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7C5BAD1320A0D1DA

Hi and Welcome !

Execute this in Terminal :

sudo apt-get clean all
sudo apt-get update

In case, warning appears again, post the contents of /etc/apt/sources.list file here.

You can ignore that warning though.

Thanks for the help but I can't run this command....

sudo apt-get clean all


Any suggestions?

W: GPG error: Index of / intrepid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7C5BAD1320A0D1DA

terminal error is

root@joemartin-laptop:/home/joemartin# sudo apt-get clean all
root@joemartin-laptop:/home/joemartin#

nothing runs when I hit enter....goes to original prompt....thanks again for newbie help....

apt-get clean all command clears cache only. Its working fine. Post the contents of /etc/apt/sources.list file now. As I mentioned earlier, there is no need to worry about above error. Its just a warning only and you can ignore it safely.

Anyways, execute this

cat /etc/apt/sources.list

Post output here.

here's output after running command....thanks again....please tell me if you notice something.
