I did upgrade to 21.05 (System freezes (only during big updates) - #29 by maxdevjs for details).
Now:
- at boot time, I am stuck in
grub rescue
- nothing that I tried really worked (all the listed filesystems are reported as unknown)
boot in dev/sda1, not encrypted
root, home in dev/sda2, encrypted
- I booted with a live USB (
20.03, older grub)
- mounted my encrypted partitions
I did not find an eloquent walk-through on grub rescue and not sure how to continue:
- should I
chroot from the live USB as in a normal installation?
- in this case, should strictly be a version equal to the installed one?
- I see that the Minimal ISO image contains “a number of rescue tools”, how can I know what tools are those?
- then directly issue a
nixos-install (configuration is already set up, used the system for several months)?
Suggestions will be extremely welcomed.

This is a ‘bit’ messy and not exhaustive, but… So far I:
- booted a
21.05 live USB
-
chrooted into my system
- all seems to be there
- I can also access my user and my configuration
tried nix-store --verify --repair --check-contents and it:
Accuses several errors (apparently, mostly kde/plasma things) and it fails with
reading the Nix store...

I downloaded yesterday the 21.05 iso (that I used in the previous attempts).
