[Bug 745011] Re: "info: unrecognized option '--convert-db'" on upgrade

[Marc MERLIN]

If I may Scott, this is an answer one might except from microsoft telling you you can't upgrade from XP to W7 without going through Vista. Obviously you know of ubuntu bug #1.
I could understand "sorry, we don't have the resources to test upgrades from any release to any release, but let me see how I can fix this bug", but not "eh, you upgraded wrong, now udev and therefore your entire system won't work, sorry"

I realize writing upgrades so that they work from older versions of the
package takes more time, but debian has been doing it for 15 years and
been doing a pretty good job of it. May I recommend trying to emulate
them a bit more here?

Back to this issue, if others get bitten by it, the workaround of udevadm.upgrade did not work for me. I had to edit the postinst script and comment out the udevadm info --convertdb line for things to continue.
Obviously this means whatever udev DB that might be important to my system will not have been upgraded, but at least I get a better chance of still having a usable system after I reboot it than leaving things as is :-/
