Try apt-get update to fix problem with packages that could not be authenticated

[Matthew Paul Thomas]

When trying to install a package produces an error about the package not being able to be authenticated, it is moderately likely that an apt-get update will fix the problem.

Therefore apt-get, instead of just saying "WARNING: The following packages cannot be authenticated!" and listing them, would be more helpful if it finished with '"apt-get update" might fix this problem.'

Similarly, Synaptic could silently update the repository listings to see if that fixes the problem, to reduce the number of times it has to present the problem as a scary confirmation alert.

I am not too sure if this has already been implemented, although the usual procedure for fixing broken updates/packages is dpkg --reconfigure -a
Can you confirm if this has been implemented yet?
