GPG is very useful, but you have to know how to use it correctly. There was a good manual on http://www.gnupg.org/. If you don’t have a key, you can either search or directly download it (if you know its number). See ‘gpg –help’ for all the commands. The ‘no ultimate trust’ message is likely because you don’t have a key yourself, which, if you’re using GPG, you should. Then, you use ‘gpg –edit ‘ and then option ‘trust’, select the proper number (5 for ultimate), and then ’save’ command. Now and then you should do ‘gpg –refresh-keys’ to collect new signatures. Have cron do it in the middle of the night, once a month or so. Also, you can write a ~/.gnupg/gpg.conf to contain the ‘keyserver hkp://subkeys.pgp.net’ so you don’t have to re-type it all the time.

I’m running debian sid/sidux. I was getting the following errors:

W: GPG error: http://ftp.debian-unofficial.org sid 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

Ran the following commands:

# gpg –keyserver subkeys.pgp.net –recv-keys 394D199524C52AC3

# gpg –export 394D199524C52AC3 | apt-key add -

I was good togo ; )

I just installed debian etch distribution found the same error while was going to upgrade it.

*********************************************************
W: There is no public key available for the following key IDs:

W: GPG error: http://security.debian.org etch/updates Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY A70DAF536070D3A1

I used the command:
wget | apt-key update
and then confirm with:
wget | apt-key list
it shows the next output:

note: its’s the double dash in front of keyserver, recv-keys and export that apparantly doen’t show up well…

Thanks all for the info.

This is what got my apt ticking again:
#gpg –keyserver subkeys.pgp.net –recv-keys 6070d3a1 ; gpg –export 6070d3a1 | apt-key add -;

The key was the last 8 hexdigits from the error seen on screen by apt-get update.

Thanks!

you have to set ‘-’ 2 times in front of keyserver and recv-keys

Thanks, your link to “mixing Ubuntu and Debian” did help me out of this message NO PUBKEY.
