Package: dpkg Version: 1.18.4 Severity: wishlist Wouldn't it be best that # dpkg -i a.deb b.deb c.deb first be sure that we even have each deb specified on the command line before proceeding? OK, and I suppose also check that their checksums are OK.
I mean doing that would never do any harm. It wouldn't even use more CPU, because you are going to have to do those checks sooner or later during the run. Not doing the check sooner instead of later ends one up in all kinds of various unintended states: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=809743#68
