Could you please actually provide error message from you apt upgrade
commands?

I am not able to reproduce this issue, the expected behavior is the one
I observe here.

Could you also please provide the error message that you are seeing
during boot?

This error message doesn't correspond what you describe. It seems that
LC_CTYPE (or LC_ALL) is set to UTF-8, not en_US.UTF-8. Are you sure your
ssh client is asking for the en_US.UTF-8 locale?
