How can I fix this? My iptables polices is blocking apt-get. Code: apt-get install chkrootkit Reading package lists... Done Building dependency tree... Done The following NEW packages will be installed: chkrootkit 0 upgraded, 1 newly installed, 0 to remove and 50 not upgraded. Need to get 247kB of archives. After unpacking 705kB of additional disk space will be used.

Don't see why you think it is an IPTables problem. Seems to me to either be a problem at the other end or a DNS problem.
Try to ping the servers: Code: ping us.archive.ubuntu.com If you get a response, it's not iptables related. The error seem to indicate a DNS kind of error.
