Nevermind, I figured out how to create an LUKS+LVM encrypted Ubuntu install using the https://help.ubuntu.com/community/EncryptedFilesystemLVMHowto instructions.
The last step must be slightly modified, and a few more steps are necessary to create the LVM. Instead of "cryptsetup luksOpen /dev/sda5 sda5_crypt" Do "cryptsetup luksOpen /dev/sda5 pvcrypt" Then: pvcreate /dev/mapper/pvcrypt vgcreate vg /dev/mapper/pvcrypt lvcreate -n <lvname> -L <size> vg ex. lvcreate -n home -L 35G vg This will create a logical volume named "home" with a size of 35 GB. You need to create a new logical volume (lvname) for each partition and set the size you want. I created three - root, home, and swap. My setup looks like this: lvdisplay -C home vg -wi-ao 35,00G root vg -wi-ao 20,00G swap vg -wi-ao 2,00G Once you've done that, Ctrl-alt-F1 to return to the setup screen. Choose Finish. You'll get an error stating that sda5_crypt couldn't be found. Select yes to return to the setup screen. Now you'll see the LVM volumes you created. Assign mount points to each volume and continue the install as normal.
