Installation of packages from not authenticated sources, how to solve ?

Asked by Scott Barras

When I try to install anything through the Software Centre I get a message asking me to check my Internet connection the I get the following error (in this case trying to install FreeCiv):

Requires installation of untrusted packages

The action would require the installation of packages from not authenticated sources.

freeciv-client-gtk freeciv-data freeciv-server

any thoughts? I have tried

sudo apt-get -f install
sudo apt-get upgrade
sudo apt-get -f install

but with no luck

Please paste the entire message into this discussion. It is likely that this is a warning and that the warning is correct. It means that Ubuntu has not certified the source of this game. Certification requires expensive audits and entails legal obligation.

When I click on install from the software centre (for this example FreeCiv), it immediately comes up with the following message:

Failed to download package files
Check your Internet connection.

The only option is to click OK, when you click OK another dialog box appears which says:

Requires installation of untrusted packages
The action would require the installation of packages from not authenticated sources.
Details
freeciv-client-gtk freeciv-data freeciv-server

If I try another program, in this case tuxguitar I get the same messages. Although the detail is different, it says:

libnss3-1d tzdata-java

System > Administration > Update Manager > Settings

On the Software Sources window, click on the Ubuntu Software tab. Under Downloadable from the Internet, put a check on Source Code.

HTH.
