an error occurred during signature verification...

[al.adab]

on a sudo apt-get update I get the following error message:

[I]Fetched 1,501B in 1s (973B/s)
Reading package lists... Done
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://dl.google.com stable Release: The following signatures were invalid: BADSIG A040830F7FAC5991 Google, Inc. Linux Package Signing Key <linux-packages-keymaster@google.com>

W: Failed to fetch http://dl.google.com/linux/deb/dists/stable/Release

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

I tried a sudo apt-get upgrade but it didn't help...can you help?

I'm getting the same error. I think google has updated their signing key, but forgot to put the public key online (i.e. we are still using the old public key).

Hi,

I'm thinking possibly the key-server was overloaded with requests. It's something that happens from time to time. Key Servers has my notes on when this occurs, in your case, you'd be wanting to add A040830F7FAC5991

Regards,

Phill.

Thanks for the information. I'm just curious why it reports BADSIG as the error.

I'm having the same issue when I update my repositories...

I tried running the apt-key command as well, but couldn't resolve the recommended server pgp.mit.edu:

root@desktop:~# apt-key adv --keyserver pgp.mit.edu  --recv-keys A040830F7FAC5991

same here. I tried
sudo apt-key adv --keyserver pgp.mit.edu --recv-keys A040830F7FAC5991 (hope I got it right) but still get exactly the same error message.

It looks like the mit keyserver is being swapped with requests. Try using the ubuntu keyserver instead.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A040830F7FAC5991

Seems to be working now thanks everyone for their help!
