NO_PUBKEY 2EBC26B60C5A2783

[Lewis Skinner]

Hi guys.

I've been running Ubuntu for some time now, and I usually perform a clean install everytime.

This time however, following installation of Maverick, I tried to add medibuntu as on these instructions:
https://help.ubuntu.com/community/Medibuntu

And, following the first command, I get terminal output as follows:

W: GPG error: http://packages.medibuntu.org maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2EBC26B60C5A2783
W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/maverick-security/Release.gpg Something wicked happened resolving 'security.ubuntu.com:http' (-5 - No address associated with hostname)

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

This is causing issues with my downloading medibuntu packages. Can anyone help?

Hi,

Make sure that the medibuntu-keyring package is installed. If not, install and run 'apt-get update', the gpg warning should disappear.
Anyway this shouldn't prevent packages installation.

It is. I've followed all instructions on the medibuntu page shown above.

I've had similar problems with other repos (below), even straight out of the box (I installed from scratch, formatting /home partition as well).

That's my other error. I've had to comment out that repo in sources.list

OK, double-checking, I did everything I ought to as per the instructions, however, it is STILL telling me that there is no public key available.

However, checking system -> administration -> software sources, 'authentication' tab, there's no medibuntu key. How can I add this?

[Gauvain Pocentek (gpocentek)]

Could you reinstall the medibuntu-keyring package using a GUI or the following command:
sudo apt-get install --reinstall medibuntu-keyring

This seemed to work for the reporter of bug #656164

Thanks

Not to worry - I've solved it!

It was a DNS error caused by resolv.conf and my router. Once I manually entered a DNS and write-protected it, I was fine
