Failed to fetch http://extras.ubuntu.com/ubuntu/dists/maverick/Release ; missing key

Thanks for your bugreport.

Is that a live-desktop install or a alternate install? On the live-system, do you get the same message when running apt-get update? what does "sudo apt-key list" display?

I can reproduce this on the live system. The package "ubuntu-extras-keyring" is installed, but "sudo apt-key list" does not show the extras signing key. A "sudo apt-get install --reinstall ubuntu-extras-keyring" fixes the issue.

From http://people.canonical.com/~ubuntu-archive/livefs-build-logs/maverick/ubuntu/current/livecd-20100928-amd64.out:
...
Setting up ubuntu-extras-keyring (2010.09.27) ...
Importing extras.ubuntu.com keyring
OK
Processing extras.ubuntu.com removal keyring
OK
...

So that looks correct.

I actually got this doing installations of both the desktop image and the alternate image. I used the Ubuntu desktop cd and Xubuntu desktop and alternate cd's.

I have this also installing the Maverick RC UbuntuStudio, using alternate DVD's , both on hardware and in VirtualBox.

The problem is that livecd.sh creates a backup of the trusted.gpg file before installing ubuntu-desktop. Then adds the buildhosts keys and then restores the backup. This removes the changes from ubuntu-extras-keyring as well.

One possible fix is:

A alternative (and simpler) version of this I commited to bzr now, it simply move the key back earlier (all key verification is done at apt-get update time). I'm testing the fix now.

This bug was fixed in the package livecd-rootfs - 1.152

Will this fix the installed ubuntu or just fix the installation process?

after reinstalling ubuntu-extras-keyring solved the problem.

So has this been updated on the most recent (as of this writing) DVD (02 October 2010)?

I installed yesterday from the prior DVD image and came across this problem.

I just wanted to note that it is (was) a problem on the DVD as well as the Live CD.

@Scott, you need to be using a daily image (not RC) to see the fix:
http://cdimages.ubuntu.com/dvd/current/

I see those date from Oct 2 though.

Can someone post how to install the fix (if possible) into an existing system (from 9/25/201 in my case)?

I tried updating ubuntu-extras-keyring, and got version 2010.09.27 which does not fix the problem...

  sudo apt-get --reinstall install ubuntu-extras-keyring

... ought to do it.

And it certainly did :)

I upgraded my machine today from 10.04 to 10.10. And I got this bug, I cant do anything, and sudo apt-get --reinstall install ubuntu-extras-keyring dosent work for me, just gives the same error, invalid package, errors were encountered while processing
Ubuntu-keyring
Ubuntu-minimal
Ububntu-extras-keyring
Ubuntu-Desktop

Plz anyone that can help`?

This error still seems to be there. When you reinstall it, it says the keys are ok, but when you run sudo apt-get update, it doesn't go away.

extras.ubuntu.com seems to have changed key since this bug was first posted, and it no longer matches the one in ubuntu-extras-keyring (2010.09.27). I imported it manually using gpg --recv with the number given in the apt-get update error message. Now when I run apt-key list this key shows up as "Launchpad Application Review Board PPA".

Instructions for importing the key manually are given here:
http://www.ubuntugeek.com/fix-for-gpg-error-httpextras-ubuntu-com-maverick-release.html

I upgraded my desktop (amd64) from 10.04 lucid to 10.10 maverick today:
aptitude update
[..]
[..]
Fetched 2,959B in 1s (1,507B/s)
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

dpkg-reconfigure ubuntu-extras-keyring
aptitude reinstall ubuntu-extras-keyring

didnt do the trick.

I've just installed Kubuntu 10.10 on my netbook and I'm getting this error too, none of the above fixes have worked.

The link I quoted above is for lucid. You need a different key for maverick:

gpg --keyserver keyserver.ubuntu.com --recv 02FDF932
gpg --export --armor 02FDF932 | sudo apt-key add -

@Linus, Mark: please say whether this works for you.

I think the extras archive is using the wrong key for maverick. It should be using the one that's in the ubuntu-extras-keyring (Ubuntu Extras Archive Automatic Signing Key) instead of this one (Launchpad Application Review Board PPA).

"sudo apt-get --reinstall install ubuntu-extras-keyring" did not work for me
Comment 23 by Neil Mayhew did work for me

@Neil Mayhew I can confirm that for maverick on a desktop install the following fixes the problem.

gpg --keyserver keyserver.ubuntu.com --recv 02FDF932
gpg --export --armor 02FDF932 | sudo apt-key add -

Following Neil Mayhew's instructions works for me too.

Neil's instructions worked for me on Maverick Desktop.

Answer #23 worked for me too.

Well, it's not that surprising that importing a missing key manually will fix warning messages about the missing key. :-)

Does this mean, ubuntu-extras-keyring will ship the singing key soon?

I dont know the procedures and details of "Ubuntu extras", but every archive/package signing key used in that repository should be shipped via the keyring package _before_ it is being used for signatures, aint it?

Thanks Neil, worked like a charm.

I don't know if I am supposed to open a new bug. In Oneiric there is the same Problem with extras it seems to affect people who had the proposed sources activated and installed alpha or beta release .

Thanks for any hint

I could not restore the keys this is what I tried (I just tried the keyring reinstall without success)

fixes the problem for me.

This bug affects Ubuntu 10.10, Maverick Meerkat. Maverick has reached end-of-life and is no longer supported, so I am closing the bugtask for Maverick. Please upgrade to a newer version of Ubuntu.
