when i try apt-get update, it updates a bit, and then an error appeared. THe error looks loke this.

Fetched 6013kB in 10m37s (9439B/s)
Reading package lists... Done
W: GPG error: http://ftp.debian-unofficial.org stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 394D199524C52AC3
W: You may want to run apt-get update to correct these problems

may i know how to solve this problem..THank you

john

the public keys from those repositories must be imported in apt-get.

you need to have gnupg package installed.

insert a command like this :

$ gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 394D199524C52AC3

$ gpg –armor –export 394D199524C52AC3 | sudo apt-key add -

this should resolve the trick.

alternatively you could search in apt-cache for the keyring if exists.

The first command will work, not the second. Below are the ones I use that work as root since I don't have sudo set up:

the second work for me. it's a matter of setup. If you set up sudo it will work as well

guys my problem starts again.....problem in my sourceslist......

I have change my sourceslist..and it looks like this

when i try to run apt-get update

this error shows
----------------------------------------------------------------------

E: Could not get lock /var/lib/apt/lists/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the list directory
-----------------------------------------------------------------------------------

what does it means....What should I do? Is it problem in the sourceslist...

that means you are not root!

or

that there's a process hanging of apt in other console. try to kill, or reboot and then try apt-get update again.

also I am not sure about the cdrom entry the one which is not commented. i would remove it. it has no use.

Make sure synaptic is not open as it is an application running apt, you can only run one instance of apt at a time, when you try to run a second instance you'll get that error.
