Signature Verification Failure

[prokher]

Looks like this old fix still does the trick. You'll need to preface all of these with "sudo" or "sudo su" beforehand.

apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update

thanks! works great!

I had to do this on lucid:

cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

Thank You jaygo. It worked here for Ubuntu 10.10.

>> wget –q "http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0xSHOULDBEYOURKEY" -O- | sudo apt-key add

This works fine,
Give a try

Thanks to Jaiber,

The old fix worked on 10.10 maverick meerkat here too but still a few issues:

I got 'Unknown id: cd' when I used the su cd /var/lib/apt command, or sudo: cd: command not found when I tried sudo cd /var/lib/apt.

So I typed this command without using sudo and got updates okay. I'm still getting the following GPG error at the end though:

W: GPG error: http://extras.ubuntu.com maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DB141E2302FDF932

I've probably missed something but not sure what. Any ideas? Thanks.

In my ubuntu 9.04 the above "old fix" solved the following error:

I haven't pulled this one out for a while but I can confirm it also worked for me. I add the following

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

Then

apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update

with sudo and it just finished updating.

Thanks I was hitting my head against a wall for a while on this one

When I type in this old fix, I get this:

evan@Trigger-laptop:/var/lib/apt$ mv lists lists.old
mv: try to overwrite `lists.old/lists', overriding mode 0755 (rwxr-xr-x)? What should I do?

EDIT

I went System---->Administration---->Software Sources and changed Source code to "Main"

I opened a terminal and entered

sudo apt-get update

and didn't get any errors.

That fixed my issue...thank you!
