[LUNI] error message from apt-get #$

[Carey Tyler Schug]

I installed the korn shell in my mainframe Linux, so I could migrate 
some shell scripts from other platforms (Solaris).

The post-install tries to run add-shell, which is not present.

Everything seems OK, I can invoke ksh, and the correct path is in 
/etc/shells.

But every time I add another package, it tries to do that post-install 
again, and gives me the error message.

I am a newbie.  How do I clear this?  Other than writing a dummy 
"add-shell" command that does nothing.

Thanks in advance.
