NO_PUBKEY 5A9A06AEF9CB8DB0

Asked by BillyBoJimBob

I'm trying to update my Linux Mint 15 Olivia box with "sudo apt-get update", but receive the following error:
W: GPG error: http://ppa.launchpad.net raring Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A9A06AEF9CB8DB0

I try "sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5A9A06AEF9CB8DB0" but receive the following error:
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.tTKIoGGbd1 --trustdb-name /etc/apt//trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys 5A9A06AEF9CB8DB0
gpg: requesting key F9CB8DB0 from hkp server keyserver.ubuntu.com
?: keyserver.ubuntu.com: Connection refused
gpgkeys: HTTP fetch error 7: couldn't connect: Connection refused
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

When I attempt to find the key directly at http://keyserver.ubuntu.com, it says it can't find the key.
Until I get past this error, I can't run "sudo apt-get update" and am prevented from installing additional programs.
Any help will be appreciated.

I found a solution. With the the following:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 5A9A06AEF9CB8DB0

I get the following response:
