Answer 1

here is the solution i had the same problem and this post helped me

http://www.ubuntugeek.com/how-to-fix-the-ubuntu-gpg-error-badsig.html

but before that i suggest you to change your source.list file using this site (optional but worked for me)

http://repogen.simplylinux.ch/

select your os version and then check all entries under "Ubuntu branches" and "Ubuntu updates" and select Ubuntu partner for those you want to receive updates. and add extra repositories if you want to.

How to change source.list?

if you have generated new source.list from repogen.simplylinux.ch then open terminal and type

gksu nautilus

go to /etc/apt/sources.list and backup source.list(rename it) copy your downloaded source.list file and run update once again

Hope that helped
