[Discuss] Unusual error message after tar ops

Clue may be 'newgrp' which is rather late in the SSH connection, that's
invoked while spawning the login shell.

It sounds like the desired User in Passwd has U#:G# that does not match the
group memberships.

(Alternatively, the group # on restored $HOME and .ssh  may be an invalid
but I don't think that would cause this precise message?)
