Ubuntu – Can’t add repo keys

12.04kubunturepository

I'm tring to add a keys (on Kubuntu 12.04)

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

and I constantly get 

gpg: requesting key 8AC93F7A from hkp server keyserver.ubuntu.com
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error

I thought my ports are closed. But the following should have made ports 80 and 11371 open:

iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 80 -j ACCEPT
iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 11371 -j ACCEPT

But I still get timed out.

Edit:

The following solves it:

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys SOMEKEY

Best Answer

The following solves it:

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys SOMEKEY

If you see something like this:

W: GPG error: http://archive.canonical.com jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5

then add the appropriate key:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

You can get a list of repos here: http://repogen.simplylinux.ch (but it is not recommended to add x-org updates - at least be sure to back up You xorg.conf)

If see errors from previous repos - empty your /etc/apt/sources.list.d dir.
