Hi!

When I installed Debian 13.4 on my laptop using the Calamares installer from the KDE live image I almost got stuck with "Attempting to decrypt master key..." if I enable disk encryption. It takes about a minute to boot. But even after that, the system won't boot but just shows me a GRUB shell ("grub> _").

Hello Kaulkwappe,

Where did you download the image from? I assume https://get.debian.org/images/release/current-live/amd64/iso-hybrid/debian-live-13.4.0-amd64-kde.iso

What was on the hard disk before you ran Calamares? Did some partitions already exist?

You write: 'almost got stuck', so you are not getting stuck? Then what is the actual issue you are reporting? (This is just me having trouble reading English)

With kind regards,

Hi Roland!

Thanks for your answer.

Well, eventually I got stuck—it stopped at the GRUB shell ("grub> _"), so the "almost" was not correct. What I actually meant was that it almost already got stuck at  "Attempting to decrypt master key..." which took way too long.

Yes, on the disk were Windows 11 installed previously. However, I selected the full disk encryption—so all got purged, not way that there were any conflicts. The laptop also has only one SSD, it's a Framework 12. The other settings; nothing unusualy, just resume, resume, resume.

The image was downloaded from here:

Unfortunately the bug still exists in 13.6. It's still impossible to install Debian on a Framework 12 laptop (i3-1315U) with the Calamares installer and full disk encryption, because you will end up in the GRUB shell ("grub> _") after entering the password which alone takes a few minutes.

The normal graphic installer doesn't have this issue. Maybe Calamares does something wrong with the boot partition, since it seems Calamares would encrypt the boot partition while the normal graphic installer would not.

Nothing, I never do dual-boot installations.
It's actually full stuck because you will end up in the GRUB shell.

Any chance someone could test that with a Framework 12 laptop (i3-1315U)?

Calamares with an encrypted disk isn't usable in that state unfortunately. I tried it multiple times on a brand new laptop.
