/bin/sh must be a POSIX compatible shell, because many scripts use it.
tcsh is not a POSIX compatible shell (it implements the C shell
scripting language instead), so you cannot change /bin/sh to tcsh.

You could install dash and symlink it to /bin/sh, because it is a POSIX
compatible shell.  Debian (and its derived distros) have used dash as
/bin/sh for a while now.
