Hello all, Apologies if this is off-topic.  I was talking to a couple of the developers a few days ago regarding my problem, so I thought that I'd post it to the list since at the moment, I'm unable to access IRC at the moment. .  To recap:   I'm running an Ubuntu 8.10 system acting the pxeboot/tftp/dhcp server for another laptop on which I'd like to install Ubuntu over the network.  The network is dirt simple, basically two laptops connected via a crossover patch cable. I'm able to get the system to boot up to the point where it tries to access  the iso which is being served via FTP.  the client installer downloads the Release file with no problem, but it seems to be having a problem (I'm guessing) with something in the preseed.cfg file. I added DEBCONF_DEBUG=5 to the pxelinux.cfg/default file and then ran a second console on the client using alt-f2.  doing a tail of /var/log/syslog shows: <date> debconf: --> GET apt-setup/security_host <date> debconf: <-- 0 192.9.200.1 <date> debconf: --> GET apt-setup/security_path <date> debconf: <-- 0 /pub/ubuntu <date> debconf: --> SET retriever/net/error Retry <date> debconf: <-- 0 value set <date>: debconf: --> INPUT critical retriever/net/error <date> debconf: <-- 0 question will be asked <date> debconf: --> GO Can someone decipher this for me?  I can't tell if the error is related to the apt-setup/security directives or something else. I've tried a number of different configurations, but something that stood out is that commenting out the apt-setup/security_host directive didn't stop the installer from retrieving the security_path directive; the next section of the preseed.cfg file is the section on additional local mirrors: # Additional repositories, local[0-9] available Do I need to uncomment these directives as well?  I assumed that the word "additional" meant that they were optional.  Thanks for any help.
