What's the problem and how can I fix it?

Solution

It seems that the mirror you're using (http://ir.archive.ubuntu.com/) is not working.

There is usually a mirror per country, identified by the their ISO two letter country code, in your case ir.

The easiest way to fix your problem is to edit your /etc/apt/sources.list and replace http://ir.archive.ubuntu.com/ by http://SOME_OTHER_COUNTRY_CODE_HERE.archive.ubuntu.com/

There are also other ubuntu mirrors listed here with their status.

thanks that worked! 1 question though how can I add the mirrors listed here in my source.list file? replace ir.archive.ubuntu.come with them? or add them in the end?
