worked for about a month, everything was ok.
Now, when loading, an error occurs https://hostingkartinok.com/show-image.php?id=d8e3...
I tried to fix it according to the instructions _ https://the-bosha.ru/2016/03/25/vosstanavlivaem-sv. .. didn't help.
Tried typing exit, didn't help either.
How to fix? I can give remote access.

Answer 1

What caused the error? Is the encrypted partition accidentally not the root? Is cryptsetup included in the initramfs?

Answer 2

The error occurred during reboot.

I don't know about cryptsetup.
I installed the system like this:
1) Launched Virtualbox without a hard drive.
2) I connected a 64gb flash drive to install the system.
3) Connected the installation disk with linuxmint 18.1.
4) Installed the system on a USB flash drive.
After that, I worked with the installed system for about a month on different computers, booting from a USB flash drive.
