Unable to install 12.10 with PXE
use apt-mirror to download missing repository main/debian-installer (about 50 MB) which is necessary for netboot installation. It was presented on alternate CD in the past.
sudo apt-get install apt-mirror
comment out all deb* lines in /etc/apt/mirror.list and add the following
deb http://archive.ubuntu.com/ubuntu quantal main/debian-installer
or
deb-amd64 http://archive.ubuntu.com/ubuntu quantal main/debian-installer
for amd64 edition of Ubuntu.
and execute sudo -u apt-mirror apt-mirror
wait a little bit and then copy downloaded files from /var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu into your netboot installation point. For example,
cp -a /var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu /var/www/
where /var/www has already contained ubuntu directory with dists and pool subdirectories.

I'm trying to install Ubuntu 12.10 with PXE (Cobbler) and Kickstart from a local server. At some point, the installation stops telling me it cannot upload a file from mirror. The install log on the workstation looks fine and here's the end of the log :
net-retriever: gpgv: Good signature from "Ubuntu CD Image Automatic Signing Key <[email protected]>" anna [4222]: cat: can't open '/tmp/net-retriever-4226-deduplicate/*': No such file or directory
I don't see any errors (404) on the apache's logs.
I have a similar setup for 12.04 that works fine and the only difference is the use of Ubuntu's alternate CD. For 12.10, I used the default ISO I added manually the netboot folder to my installation image (netboot.tar.gz uncompressed to install/netboot folder).
PXE entry looks like this:
LABEL ubuntu-12.10-i386 kernel /images/ubuntu-12.10-i386/linux MENU LABEL ubuntu-12.10-i386 append initrd=/images/ubuntu-12.10-i386/initrd.gz ksdevice=bootif lang= preseed/url=http://10.0.0.1/cblr/ks_mirror/ubuntu-12.10-i386/preseed/ubuntu.seed locale=en_US text kssendmac priority=critical ks=http://10.0.0.1/cblr/svc/op/ks/profile/ubuntu-12.10-i386

user99905 over 11 yearsThanks for the info but I decided to go the Cobbler way : I used the command 'cobbler-ubuntu-import' that downloads the mini iso, creates the distribution, the profile and the repos in Cobbler. I then activated the repos in Cobbler to download the repository. With that method, everything is controlled from within Cobbler.

Pat over 11 yearsIt's unbelievable why Ubuntu does not make of every Ubuntu ISO a valid Ubuntu repository. this is really nuts;

Admin over 10 yearsThanks for this first. But when i do exactly what you say, the installation says that the MD5Sum is missmatched :(. I think file Release in the CD repo is differ than the apt-mirror Release. I still get stuck at this

Danduk82 about 10 yearsYou better should create a link between mirror files and /var/www/ by
ln -s /var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu /var/www/ubuntu
or mount it as a bind file-system. In this way you don't need to copy 100Gb of disk 2 times, and all the files get synchronized when the mirror is updated. Anyway, thanks for the main/debian-installer part of the config file. This is what was missig to me. Cheers
