Please help me to install g++ on Ubuntu. The version of gcc is 4.6.3
Thank you so much
I'd faced a similar issue few months back. I changed the repository server from lk.archive.ubuntu.com (which ubuntu had installed by default) to ubuntu main server which is archive.ubuntu.com. Did an "apt-get update" after that and all went smooth.
The regional servers are down sometimes. You may also try changing from the US to the main server. You can do this either by hand editing the /etc/apt/sources.list file or from the ubuntu software centre in a click of a button.
