    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.
    Err http://us.archive.ubuntu.com dapper/main chkrootkit 0.46a-2
      Temporary failure resolving 'us.archive.ubuntu.com'
    Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/c/chkrootkit/chkrootkit_0.46a-2_i386.deb  Temporary failure resolving 'us.archive.ubuntu.com'
    E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
    
    Code:
    iptables -L
    Chain INPUT (policy ACCEPT)
    target     prot opt source               destination
    ACCEPT     tcp  --  anywhere             anywhere            tcp dpt:ssh

    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.
