  • Looks like a malformed URL in APT somewhere. OP, can you post your /etc/apt/sources.list? – thomasrutter Apr 16 '15 at 3:42
  • You might want to think on an upgrade to 14.04LTS because 13.10 is an EOL release and is no longer supported. help.ubuntu.com/community/TrustyUpgrades – JoKeR Apr 16 '15 at 17:37

I think you have installed the the key viewizard-gpg.asc from this URL with these commands:

wget http://www.viewizard.com/linux/viewizard-gpg.asc
sudo apt-key add viewizard-gpg.asc

But there is no key and no repository any more.

Remove these lines from your sources.list, and the problem is fixed.
