I disagree. A postinst script should not fail for reasons like this. It may be run during a complex system operation (like a upgrade) and a failing postinst will have consequences that go beyond the single package. It should instead setup a debconf note or something like this (or just do nothing).
But I guess I have to take this argument over to debian :) -- [can-not-install] maintainer script failure https://launchpad.net/bugs/93721 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
