Related to that, I found this old bug:

  https://issues.guix.gnu.org/35543

I tried to reproduce it:

  0. I chose a basic installation to a fully-encrypted disk with a
     single partition.

  1. I hit Ctrl-C while ‘guix system init’ was downloading substitutes.

  2. That led me to a confusing error screen says “Command cryptsetup
     failed” with Ignore/Abort/Retry buttons.  This should have been
     “Command guix system init” failed no?

  3. I resumed starting with the “Configuration File” step, and there
     ‘guix system init’ ran to completion just fine.

Maybe the difference is that you hit Ctrl-C when ‘guix system init’ had
already started copying stuff to /mnt?

Thanks,
Ludo’.
