sudo apt-get update error

Question

I am getting following errors repeatedly upon using apt-get update command :

Ign http://mirrordirector.raspbian.org jessie InRelease
Err http://mirrordirector.raspbian.org jessie Release.gpg                      
  Something wicked happened resolving 'mirrordirector.raspbian.

I also could not access my internet through raspbian browser

Answer 1

Your domain name cob.apac.bosch.com makes me almost certain you're behind a corporate firewall with no internet access, which is the reason for the errors you're seeing.
