I am unable to update through software updater. After clicking install now, it shows "requires installation from untrusted package".

Then there is two options: Settings and OK. I click OK but the software updater window closes and stops.

  • @user204983 upload it into imgur.com and paste the link into your question editing it. You can try to solve the problem following this procedure. Tell us if that doesn't work – Lucio Mar 13 '14 at 04:25
  • Looks like key error issue. Some repository site's gpg key is missing maybe. run in terminal (sudo apt-get update), post the output(last section/errors). – shantanu Mar 13 '14 at 04:43

might be useful to look at your sources file you can get it like this:

cat /etc/apt/sources.list

but you might try this:

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
