Hi There,
I have been working on getting Ubuntu 7.10 to install over the network
as we have loads of servers which we need to install. I am currently
having a problem where I am unable to get the console redirection over
serial to work through the installer. The screen never draws correctly.
Here is what I have on my pxelinux configuration for the ubuntu install
in question
label ubuntu-console
kernel ubuntu-installer/amd64/linux
append tasks=standard debconf/priority=critical
preseed/url=http://192.168.10.1/gutsy/gutsy-preseed.cfg
netcfg/choose_interface=eth0 netcfg/dhcp_timeout=60 locale=en_GB
console=ttyS0,19200n81 initrd=ubuntu-installer/amd64/initrd.gz
In the gutsy-preseed.cfg config I have the following
# Ubuntu archive mirror hostname:
d-i mirror/country string GB
d-i mirror/http/countries select GB
d-i mirror/protocol select http
d-i mirror/http/hostname string gb.archive.ubuntu.com
d-i mirror/http/directory string /ubuntu/
d-i mirror/suite select gutsy
d-i mirror/codename string gutsy
# Ubuntu archive mirror:
d-i mirror/http/mirror select gb.archive.ubuntu.com
apt-mirror-setup apt-setup/non-free boolean false
apt-mirror-setup apt-setup/use_mirror boolean true
apt-mirror-setup apt-setup/restricted boolean true
apt-mirror-setup apt-setup/universe boolean true
apt-mirror-setup apt-setup/multiverse boolean true
apt-mirror-setup apt-setup/contrib boolean false
apt-mirror-setup apt-setup/backports boolean true
# Disk Setup
d-i partman-auto/disk string /dev/sda
d-i partman-auto/method string regular
partman-auto partman-auto/init_automatically_partition select
Guided - use entire disk
partman-auto partman-auto/automatically_partition select
d-i partman-auto/purge_lvm_from_device boolean true
d-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition select Finish partitioning and write
changes to disk
d-i partman/confirm boolean true
# Network Configuraiton
d-i netcfg/choose_interface select auto
d-i netcfg/get_hostname string unassigned-hostname
d-i netcfg/get_domain string unassigned-domain
# Disable that annoying WEP key dialog.
d-i netcfg/wireless_wep string
d-i console-setup/variant select United Kingdom
d-i console-setup/charmap select UTF-8
d-i clock-setup/utc boolean true
d-i time/zone string Europe/London
d-i console-tools/archs select uk
d-i debian-installer/locale string en_US
d-i passwd/root-login boolean true
d-i passwd/root-password-crypted password XXXXXX
d-i passwd/make-user boolean false

tasksel tasksel/first multiselect lamp-server
d-i pkgsel/include string openssh-server ntp-server ntpdate dmsetup
screen multipath-tools multipath-tools-initramfs lvm2 snmpd scsiadd
The install works perfectly If I plug a monitor and keyboard into the
system, If I want to install remotely via the serial connection (as we
have with Debian, Redhat and even SuSe) the screen does not draw
correctly and results in the screen going blue and refreshing like mad
as a blank screen. I have checked all the terminal settings and they are
all 19200 N81.
Regards,
Jimmy
