Comment 31 for bug 1066480

I can't believe encrypted volumes is still such a hastle on Ubuntu. I haven't seen this with any other distro I've used. Even Archlinux is easier, because you actually know why it is or isn't working. On Ubuntu, you push a few buttons, and hope it boots when you're done. Absraction is great when it actually works. Otherwise you're just SOL, with no clear troubleshooting steps. This really needs to be fixed.

This is the first time I've tried this without the alternate install CD, which required a different set of post-install interventions to get working. If you, like me, followed the workaround and ended up at the initramfs prompt, this is what you need to do:

In addition to selecting mount points and FS types for your encrypted volumes, you also need to select the containing physical volume, and set it as "Physical disk for encrypted volumes," or something like that.

It's great to make things easy with a GUI installer, but there really should be instructions for how to do this stuff manually, so you have a some recourse when it doesn't work. Other than trying random install options or forum suggestions until it succeeds, but you don't know why. Thus far I've been unable to find such a thing for Ubuntu. Without good documentation, you also discourage contributors from helping to solve the problem.
