When I launch an unattended install with VirtualBox and Debian 9 / Ubuntu 18.0.4, the installation stops on the screen where the country is to be selected:

Language selection in Debian 9 Language selection in Ubuntu Server 18.0.4 LTS

This is my command line:

VBoxManage unattended install $VMNAME --user=$OSUSERNAME --password=$OSPASSWORD --country=UK --time-zone=UTC --hostname=testserver.local --iso=./build/$ISOFILENAME --install-additions

VBoxManage startvm $VMNAME --type headless

I have also tried the hints given in the VirtualBox documentation, which lists an additional parameter for the language:

VBoxManage unattended install $VMNAME --user=$OSUSERNAME --password=$OSPASSWORD --country=UK --time-zone=UTC --hostname=testserver.local --iso=./build/$ISOFILENAME --install-additions --language=en-US

... no success. This is the output of the scripts:

How can I run a 100% unattended installation of Debian 9 or Ubuntu 18.0.4 LTS in VirtualBox?

  • It seems to be a feasible solution to install via packer and a seed file. - At least, this worked for me.

There's an issue with syslinux on debian from Stretch onwards: it automatically starts the graphical installer instead of starting the install menu entry.

You can find more details about the issue and a fix here: https://www.virtualbox.org/ticket/18410

Basically the fix consists in using VirtualBox's --auxiliary-base-path to specify the location where Virtualbox should extract isolinux files from the ISO and patch them.

aux_base_path="$(mktemp -d --tmpdir unattended-install-XXXXX)"

VBoxManage unattended install 'vm-name' --auxiliary-base-path "$aux_base_path"/ ...

(... is a placeholder for your other options)

It's now possible to patch the main isolinux configuration file to run the install menu entry by default instead of the VESA menu:

sed -i 's/^default vesa.*/default install/' "$aux_base_path"/isolinux-isolinux.cfg

Now you can start the VM and unattended installation should take place:

VBoxManage startvm 'vm-name'

Note: the commands above are for unix shell (Linux & MacOS). For Windows console, use an existing folder path like %UserProfile%/ instead of "$aux_base_path/" and use:

$f = Get-Content isolinux-isolinux.cfg | %{$_ -replace "^default vesa.*","default install"}
$f > isolinux-isolinux.cfg
