Precision 7540

Base System

Install Debian Gnome on preconfigured luks/lvm disk:

1. Use Expert Install from the netinst ISO.
2. Select rescue-mode in "Load installer components from installation media" step.
3. Before the "Partition disks" step, select "Execute a shell".
4. Use cryptsetup open on your LVM partition. Use lvs to confirm that your logical volumes are visible.
5. Exit the shell and select "Partition disks". Use manual partitioning and mount the right LVs at /, /home, and swap.
6. Proceed with the remaining installation steps, but stop before "Finish the installation".
7. Go to "Execute a shell" again and edit /target/etc/crypttab to unlock your LUKS partition on boot.
8. Exit the shell and select "Finish the installation".

Ad 7: The UUID must be filled, I used this command:

cryptsetup luksDump /dev/sda3 | grep -F UUID >> /target/etc/crypttab

Then I edited the file:

nano /target/etc/crypttab

cat /target/etc/crypttab
sda3_crypt UUID=[UUID from luksDump] none luks,discard

I also had to do:

update-initramfs -u -k all
