This is a bug in udev only... if udev wants to diverts its own file it must not use "--package udev" otherwise it instructs dpkg to divert the file EXCEPT when it's provided by udev (which it does). So in reality the replacement /sbin/udevadm is only there for a short time and overwritten by the new udevadm.
And then the postinst reinstalls the old udevadm which has been copied into /sbin/udevadm.upgrade (from the previous version) which supposedly does not support the --convert-db option. I suggest to use "--package fake-udev" or "--local" instead (but --local is meant to be used by the admin in theory and might generate a lintian warning). ** Changed in: dpkg (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745011 Title: "info: unrecognized option '--convert-db'" on upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
