Problem installing any software non-regarding of source

Asked by Nishant

My internet is working properly though whenever i try to install any software from software center i am given a error msg saying check ur internet connection and following that another msg is shown that "The action would require the installation of packages from not authenticated sources" and i makes me to close it and finally installation fails , i received that msg when installing from sources other that software center . I would like to add that i recently downloaded Ubuntu 11.10 64-bit and have installed with Windows-7 Ultimate 32-bit as "software" in Win7 from options given to choose how to install Ubuntu while installing from CD. Thanks

What package are you attempting to install?

A known fix for this unchecking 'Proprietary Drivers' and 'Software Restricted by copyright or legal issues' in your software sources settings of your package manager.

@actionparsnip:The output is as below:
W: Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ - Release amd64 (20111012)/dists/oneiric/Release Unable to find expected entry 'restricted/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

@Steffan Wood: Erros comes whatever software i want to install.

ok then in software centre you can disable the CD as a package source, or you can comment out the line in /etc/apt/sources.list

Should then be smooth

Can you help with this problem?
