Maverick: Installing Extras from livecd fails to import gpg pubkey

[philinux]

Binary package hint: ubiquity

After a clean install and performing updates the following error occurs.

Err http://extras.ubuntu.com maverick Release

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://extras.ubuntu.com maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192

Solution is easy if you a very familiar to ubuntu.
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192

same issue after installation. if we can't get the fix incorporated into the release, could we at least get instructions for adding the repo and key on the home page of http://extras.ubuntu.com ?

I did an upgrade from karmic to Maverick. With this bug as a result.

I did the easy step with following result:

tom@tom-laptop:~$ apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192

gpgkeys: HTTP fetch error 7: couldn't connect to host
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Repeated the trick with several other keyservers with the same result. What is happening?

The workaround works for me thanks.

@tinytom - you need to run this with elevated privs. prepend "sudo" or elevate with su first.

There is another LP bug which is worth tracking (#645436) on this issue; it's about the creation of the "ubuntu-extras-keyring" package which is meant to provide this missing GPG key.

Works if I install the ubuntu-extras-keyring package, so marking as a duplicate.

I'm receiving this error and ubuntu-extras-keyring v 2010.09.27 IS installed. I attempted to reinstall but it still fails.

+ I installed maverick to disk with updates and enable repo from the Maverick LiveCD

After installing and rebooting doing an update yields:

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. 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

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/maverick/Release

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

It's already installed and I am still receiving this message.

[infurnus (axemaninferno)]

Fixed. I had a different key missing. I recently discovered you can use the last 8 chars of the key that the error yields.

To infurnus. I had the above problem with a couple of keys in 11.04 Natty version. Tried your steps and it worked just fine! Thanks a million! I am just so glad there are guys like you who can actually figure things out before it is fixed officially! Happy New Year to you if you get it beforehand!

Status changed to 'Confirmed' because the bug affects multiple users.
