Read the "Question Guidelines" link in my posting signature; what do you think anyone will be able to tell you based on what you posted? A generic error message, no details (version/distro of Linux, what you're trying to install from where, how, etc.), doesn't tell us anything that would let us help you.

Past that, did you run the command the system suggested???

Thanks for reply but i solved the issue or thanks again that you helped me.

So how about posting what you did to solve the issue???

Thanks again that you are giving me chance to help somebody.
