apt-get install flashplugin-installer and ttf-mscorefonts-installer via proxy

My desktop has not direct internet access but goes through a proxy. It fails to install the packages like flashplugin-installer or ttf-mscorefonts-installer. There are 2 solutions:

• edit /etc/wgetrc

  sudo vi /etc/wgetrc

  http_proxy = http://your-proxy.your.org:3128

  substitude the proxy address and the port 3128 with your proxy address and port number. Save the file then run

  sudo apt-get install flashplugin-installer ttf-mscorefonts-installer

• or for one-off installation:

  sudo http_proxy=http://your-proxy.your.org:3128 apt-get install flashplugin-installer ttf-mscorefonts-installer
