Interactive live server installation on IBM Z LPAR (s390x)¶
Doing an interactive (manual) live installation as described here - meaning without specifying a parmfile - has been supported in Ubuntu Server since LTS 20.04.5 (‘Focal’).
The following guide assumes that an FTP server to host the installation files is in place, which can be used by the ‘Load from Removable Media and Server’ task of the Hardware Management Console (HMC).
Download and mount the ISO¶
Download the ‘focal daily live image’ (later 20.04.5 image).
Now loop-back mount the ISO to extract the four files that are needed for the installation:
user@workstation:~$ mkdir iso
user@workstation:~$ sudo mount -o loop ubuntu-20.04.5-live-server-s390x.iso iso
user@workstation:~$
user@workstation:~$ ls -1 ./iso/boot/{ubuntu.exec,parmfile.*,kernel.u*,initrd.u*}
./iso/boot/initrd.ubuntu
./iso/boot/kernel.ubuntu
./iso/boot/parmfile.ubuntu
./iso/boot/ubuntu.exec
Make the files available via your FTP server.¶
Open the IBM Z HMC and navigate to ‘Systems Management’ on your machine.
Select the LPAR that you are going to install Ubuntu Server on. In this example we use LPAR
s1lp11.Now select menu: ‘Recovery’ –> ‘Load from Removable Media or Server’ task.
Fill out the ‘Load from Removable Media or Server’ form as follows (adapt the settings to your particular installation environment):
Load from Removable Media, or Server - <machine>:s1lp11 Use this task to load operating system software or utility programs from a CD / DVD-ROM or a server that can be accessed using FTP. Select the source of the software: o Hardware Management Console CD / DVD-ROM o Hardware Management Console CD / DVD-ROM and assign for operating system use o Hardware Management Console USB flash memory drive o Hardware Management Console USB flash memory drive and assign for operating system use * FTP Source Host computer: install-server User ID: ftpuser Password: ******** Account (optional): File location (optional): ubuntu-live-server-20.04.5/boot
You may need to adjust the file’s location according to your install server environment.
Confirm the entered data:
Load from Removable Media or Server - Select Software to Install - <machine>:s1lp11 Select the software to install. Select Name Description * ubuntu-live-server-20.04.5/boot/ubuntu.ins Ubuntu for IBM Z (default kernel)
Confirm again that jobs might be cancelled if proceeding:
Load from Removable Media or Server Task Confirmation - <machine>:s1lp11 Load will cause jobs to be cancelled. Do you want to continue with this task? ACT33501
And confirm a last time that it’s understood that the task is disruptive:
Disruptive Task Confirmation : Load from Removable Media or Server - <machine>:s1lp11 Attention: The Load from Removable Media or Server task is disruptive. Executing the Load from Removable Media or Server task may adversely affect the objects listed below. Review the confirmation text for each object before continuing with the Load from Removable Media or Server task. Objects that will be affected by the Load from Removable Media or Server task System Name Type OS Name Status Confirmation Text <machine>:s1lp11 Image Operating Load from Removable Media or Server causes operations to be disrupted, since the target is currently in use and operating normally. Do you want to execute the Load from Removable Media or Server task?
The ‘Load from Removable media or Server’ task is now executed:
Load from Removable media or Server Progress - P00B8F67:S1LPB Turn on context sensitive help. Function duration time: 00:55:00 Elapsed time: 00:00:04 Select Object Name Status * <machine> s1lp11 Please wait while the image is being loaded.
This may take a moment, but you will soon see:
Load from Removable media or Server Progress - <machine>:s1lp11 Function duration time: 00:55:00 Elapsed time: 00:00:21 Select Object Name Status * <machine> s1lp11 Success
Close the ‘Load from Removable media or Server’ task and open the console a.k.a. ‘Operating System Messages’ instead. If no parmfile was configured or provided, you will find the following lines in the ‘Operating System Messages’ task:
Operating System Messages - <machine>:s1lp11 Message Unable to find a medium container a live file system Attempt interactive netboot from a URL? yes no (default yes):
By default, you will now see the interactive network configuration menu (again, only if no parmfile was prepared with sufficient network configuration information).
Proceed with the interactive network configuration – in this case in a VLAN environment:
Unable to find a medium container a live file system Attempt interactive netboot from a URL? yes no (default yes): yes Available qeth devices: 0.0.c000 0.0.c003 0.0.c006 0.0.c009 0.0.c00c 0.0.c00f zdev to activate (comma separated, optional): 0.0.c000 QETH device 0.0.c000:0.0.c001:0.0.c002 configured Two methods available for IP configuration: * static: for static IP configuration * dhcp: for automatic IP configuration static dhcp (default 'dhcp'): static ip: 10.222.111.11 gateway (default 10.222.111.1): 10.222.111.1 dns (default 10.222.111.1): 10.222.111.1 vlan id (optional): 1234 http://cdimage.ubuntu.com/ubuntu/releases/20.04.5/release/ubuntu-20.04.5-live-server-s390x.iso (default) url: ftp://10.11.12.2:21/ubuntu-live-server-20.04.5/ubuntu-20.04.5-live-server-s390x.iso http_proxy (optional):
After the last interactive step here (that this is about an optional proxy configuration), the installer will complete its boot-up process:

If the ‘Integrated ASCII Console’ was opened (you can hit F3to refresh the task), the initial Subiquity installation screen is presented, which looks like this:
================================================================================

Since the user experience is nicer in a remote SSH session, we recommend using that. However, with certain network environments it’s just not possible to use a remote shell, and the ‘Integrated ASCII Console’ will be the only option.
Note: At the end of the installer boot-up process, all necessary information is provided to proceed with a remote shell.
The command to execute locally is:
user@workstation:~$ ssh [email protected]
A temporary random password for the installation was created and shared as well, which you should use without the leading and trailing double quotes:
"C7BZrW76s4mJzmpf4eUy"
Hence the remote session for the installer can be opened by:
user@workstation:~$ ssh [email protected]
The authenticity of host '10.222.111.11 (10.222.111.11)' can't be established.
ECDSA key fingerprint is SHA256:P+hBF3fj/pu6+0KaywUYii3Lyuc09Za9/a2elCDOgdE.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '10.222.111.11' (ECDSA) to the list of known hosts.
[email protected]'s password: C7BZrW76s4mJzmpf4eUy
One may swiftly see some login messages like the following ones:

Depending on the installer version you are using you may face a little bug here. In that case the button will be named ‘Continue without network’, but the network is there. If you see that, just ignore it and continue … (If you wait long enough the label will be refreshed and corrected.)

It’s a nice and convenient new feature to add the user’s SSH keys during the installation to the system, since that makes the system login password-less for the initial login!
