System won't boot with automatic partitioning and encryption

[philmmanjaro]

Describe the bug
On Manjaro we currently face the issue that with automatic partitioning with encryption the system won't boot. I'm tested a Gnome Dev Image with latest Calamares. We also have a Gnome Dev Image with 3.2.39.3.

To Reproduce
Steps to reproduce the behavior:

1. Install Manjaro with automatic mode and luks encryption
2. Reboot the system to the installed OS and try to enter the password
3. You will land in grub-rescue

Expected behavior
Boot up normally after entering the password

Screenshots and Logs

Summary Swiss-German

Summary US English

Boot Swiss-German

Boot US-English

Logs:

• Swiss-German Install
• US English Install

Additional context
I've to still check the grub.cfg files and maybe other distributions Arch-based. Also I only tested BIOS on Virtualbox so far. EFI installs are still open to be tested on my end.

This seems like a duplicate, but then we should close the others as dupes of this one on the assumption that you're equipped to provide useful logs and other debugging information.

Well, I've an update. English works. I entered asdfg instead of asdfgh, which was the password. So this leads to the issue with keyboard layouts in grub not in English ...

The keyboard issue regarding that cannot be solved in calamares at all as long grub doesn't change how that works.

While it would be technically possible, every distribution grub update will override that, besides that calamares should not
have any businesses modifying grub images.

[philmmanjaro]

Here is the grub.cfg file of the English installation. There I see a set lang=en_US ...

So in the end it is a keyboard layout issue by defaulting to US-EN on grub stage1. I found this tutorial on how to change it to DE-AT. Might work for other layouts also.

Similar topic was discussed in our old forums.

Here is another one. Maybe we can implement some like this into Calamares.

Here is the grub.cfg file of the English installation. There I see a set lang=en_US ...

The grub.cfg doesn't matter for the decryption password, you can set it to what you wish, the input will be always EN for that,
bc is what grub supports as default in his core image.

Basically, for that to work, you need to take the exact keyboard layout from /usr/share/X11/xkb/symbols/, then kbdcomp compile it to
somewhere in /boot/grub/, then modify input method in the config and insmod keylayouts and at_keyboard, etc..

This stuff needs to be done from the distribution, not calamares, IOW the grub2-update script or whatever is called has to do this.

[philmmanjaro]

Well, this might need to be the case when /boot is not encrypted, which brings us to this issue: #1311

[apt-ghetto]

The problem was described in #1203 and I provided also a possible solution how to solve/workaround it in Calamares.

Grub has only the american keyboard layout. Either the distribution delivers a Grub core image with your needed (or all) keyboard layout(s) (the core.img is then also signed and Secure Boot ready).
Or you workaround it by compiling the keyboard layout into the Grub core image, but then Secure Boot will not work anymore.
