You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
dassault-systemes-draftsight:i386 : Depends: sendmail:i386 but it is not installable
PreDepends: libdirectfb-extra:i386 (>= 1.2.7-2) but it is not going to be installed
PreDepends: libxcb-render-util0:i386 (>= 0.3.6-1) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
什么都没发生 !
