Also test this command:

ping 8.8.8.8

Does it work?

Thanks Mark Rijckenberg, that solved my question.

It worked to ping 8.8.8.8
and on comment #3 that worked and solve the problem !! So many Thanks and I wonder why this happens?

Thank you again Mark.

Repository (containing updates) must have been temporarily down....

Hi,

I'm having the same problem, I've changed my setting to a local mirror, but it still gives the same error.

I have disabled my anti-virus and all firewalls but still no luck.

I am able to ping 8.8.8.8 successfully.

Please help!

Thanks Mark Rijckenberg, I changed the server pointing to "Main Server" using "Software Updater" and it worked.
