my system has python 3.2.3 while upgrading, it is failing like-->
W: Failed to fetch
http://security.ubuntu.com/ubuntu/di...ty/Release.gpg Could not resolve 'security.ubuntu.com'
W: Failed to fetch
http://archive.canonical.com/ubuntu/...al/Release.gpg Could not resolve 'archive.canonical.com'
W: Some index files failed to download. They have been ignored, or old ones used instead.
I tried with commands:
sudo cp /etc/apt/sources.list ~/
sudo apt-get update
again same error getting.
Can anyone please give a suggestion?
