I have tried the following solutions which were in a closed case titled "The following signatures were invalid":

First of all try

sudo apt-get clean

sudo apt-get update && sudo apt-get upgrade

Some ISPs cache the packages and errors like these are reported then. 
If the above commands don't work, try

sudo apt-get update -o Acquire::http::No-Cache=True

and again

sudo apt-get update && sudo apt-get upgrade

If it still doesn't work,

sudo apt-get update -o Acquire::BrokenProxy=true 

sudo apt-get update && sudo apt-get upgrade
gnupg signature

  1. Try this one :

    sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

  2. You have an "interesting" set of PPAs installed:

    The one's reporting BADSIG can be solved by following this Q&A:

    What is the easiest way to resolve apt-get BADSIG GPG errors?

    The 404 errors basically mean those PPA's no longer have oneiric repositories. You should untick those from Software Sources.

    The jaunty-getdeb & badgerports.org repositories are not valid for oneiric. Again, untick those from Software Sources.

  3. I got "Y PPA Manager". There is an "advanced" button in this software that will find your missing keys. Worked for me.

  4. i had the same issue. I just unchecked the "independent-provided by third-party software developers" and "independent(source code)-provided by third-party software developers" check boxes under software sources (click on the gear icon on the main panel then click on software updater. on the bottom left is the settings button which will lead you to the software sources dialogue. when you get here, just move to the 'other software' tab)
