Reinstall Network-Manager in Ubuntu

 Assumptions: Network-Manager is somehow lost (or currepted) while updating/deleting some software and Internet access is lost. Internet access was there using data-cable usb port using mobile-internet connection. Get Logical Name of the port: Type in terminal  <sudo lshw -C network> you will get list of ports with there logical name Connect to internet using command: <sudo dhclient <your_port_name>> e.g. in my case it was <sudo dhclient usb0> Then reinstall Network-Manager using command: < sudo apt-get install network-manager> Done!
