When I struggle to set up the Lexmark inkjet printer driver "lexmark-inkjet-09-driver-1.0-1.i386.deb.sh" in 9.10, When provoked for Admin password I find the note "Incorrect password given, Please Retype" worked very well with 9.04 (of course!) some help ? Please!

The printer is working very fine at other place. I just can't get by the incorrect password error.
