Unattended Install has garbled EULA screen on first boot

[ed-at-protectli]

When using an unattended installation with 8.2.0, the first (or subsequent) boot shows the EULA acceptance screen, but the text appears to be broken.

greppable text:

/usr/share/doc/* folders.grams, please read each COPYING file in thenow more

Our answerfile is as follows:

<?xml version="1.0"?>
    <installation mode="fresh">
        <primary-disk>sda</primary-disk>
        <keymap>us</keymap>
        <root-password type="hash">!!</root-password>
        <source type="url">http://[redacted]/xcp-ng/8.2.0/</source>
        <admin-interface name="eth0" proto="dhcp" />
        <timezone>Europe/Paris</timezone>
    </installation>

This only appears on some hardware, as the appropriate screen will show on other hardware using the same installation method. I wish there was some way to reliably reproduce it, but it seems specific to the host hardware. Any additional information you'd like about the hardware can be supplied, but it's difficult to just provide something succinct as this is on development OEM hardware (e.g. I can't just link to some document with all hardware specs).

Hi!

We are aware of this, and IIRC it's fixed in our master branch. However, it requires to build a new ISO. If you like, we can do it for you but we won't replace the already existing publicly available one before a bit.

It is also possible to fix it with a script called by the answerfile, during the installation process, without waiting for new ISOs.

A script returned by the answerfile seems like the path of least resistance for us. We haven't set up a build environment for xcp-ng and just rely on the released ISOs.

If there is a specific commit/pr/etc that I can refer to that has the fix, I'd appreciate being pointed in the right direction.

The fixed EULA can be found at https://github.com/xcp-ng/branding-xcp-ng/blob/master/branding/EULA and must be copied the one in /EULA on the installed system IIRC.

You can define a script to be run in the context of the installed system with <script stage="filesystem-populated" type="nfs|url">url</script>. See https://github.com/xcp-ng/host-installer/blob/master/doc/answerfile.txt#L104.

The first argument passed to the script is the path to the directory where the filesystem is mounted.

Oh, the fix is literally just replacing a single text file. I was thinking this was a much more convoluted issue with ncurses/xsconsole. I'll just repackage our image with the new file. I misunderstood the earlier comments, assuming that a true "build from source" was needed, instead of just replacing a single file in the finished image. Thanks, guys!
