when trying to install a download manager (i have a very slow and unreliable bb connection)such as KGET, TUCAN or FILEZILLA from the software centre (mav 10.10)i get...

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

And then i am not able to download, what can I do to solve it ?
cheers again

No need to reboot . The invalid key should be in your software sources . Try System> Administration > Synaptic Package Manager > Settings > Repositories > Authentication and find out what the key is for. There may be a way to validate it.

Re: Signature Verification Failure
Looks like this old fix still does the trick. You'll need to preface all of these with "sudo" or "sudo su" beforehand.
Code:
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update

and i can now download for repository.
so thanks frogs hair
and thanks jaygo
