Hi Guys,

I tried to run apt-update and get this error.

I recently swapped out my dvd drive but have not configured not sure if I need to.

I also have issues with other apps so I'm thinking I need to edit some conf files?

Any help is alsways welcomed!

Anyway this is my error info:

W: GPG error: http://security.debian.org lenny/updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD55BE302B

E: Some index files failed to download, they have been ignored, or old ones used instead.

If you're trying to use the CD/DVD you need to get the DVD drive configured. If you just need to use the online repositories, then you need to edit /etc/apt/sources.list and comment out (i.e. put a "#" symbol in front of) the lines that start with cdrom:.

The GPG problem means you probably need to install the apt key.

Honestly, the first is so common: http://www.google.com/search?client=...utf-8&oe=utf-8

The second is as pljvaldez said

I still nedd to set my new dvd drive to be recognized as the default drive. Any ideas ???

You can either create a symlink to the proper device or edit /etc/fstab so that it is mounted at the proper mount point.
