I am having problems with the following (in an attempt to remove hyperlinks, I have removed one of the "/" from the addresses):

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
