Problem in updating my system

[bulls_eye]

Hi,
I have am very new to Ubuntu and I have installed Ubuntu inside windows like a software.
As I started using Ubuntu I realized the need to use vlc media player and flash player.
I browsed the web to search for the method to install them and i got the commands
sudo apt-get update
sudo spt-get install "software name"

but sadly I am unable to update my system and whenever I try I get error

W: Some index files failed to download, they have been ignored, or old ones used instead.
W: You may want to run apt-get update to correct these problems

Note that my internet is working fine and I also made network settings in the terminal with commands like

http_proxy=http://user:password@hostname:port
https_proxy=http://user:password@hostname:port
ftp_proxy=http://user:password@hostname:port

still no results.

Please help.
