apt-get error in linux mint
The last time when I went to my relatives home which had a good internet connection. I had faced some issues with apt-get.

- I tried a lot changing the servers in sources softwares.
- But, the solution was simple. The network had an authentication for the internet from ISP.
- When I switched to the other/Mobile network.
This problem got resolved. :- wierd!
