Ubuntu Studio will not download several programs as not trusted...

Good day, I am using Ubuntu Studio I think 12.04 5 year release. It will download some software such as CLAM AV. Even after I authenticate with a password, it reads that the software requires untrusted packages and offers "OK" and "Repair". Neither option leads to a successful download.

What can I do? I will try looking for the manual.

Disclaimer: I do not use Ubuntu or Studio, I supply this information as a Debian user.

this usually comes when the appropriate "keyring" package is not installed, and so the packages can not be verified as legitimate. If you are using Synaptic, click the search button, and check for a package with the name containing "ubuntu", "studio", "keyring" or some combination of the three. Install or upgrade that package, then try again. The warning should go away.

If not, they may use some other naming scheme for their keyring packages, or the key is installed in another fashion.
