[Bug 1743447] [NEW] Can't unlock an encrypted disk when installting new ubuntu

[Maraschin]

Public bug reported:

I can't unlock an encrypted disk neither using app disks or sudo cryptsetup luksOpen when doing a new ubuntu installation...
I tried on Ubuntu daily 18.04 LTS (2018-01-15) and ubuntu 17.10

I'm trying to do a new installation of ubuntu, but I want to use encrypted disks and a dual boot for windows.
Basically I can't use the normal installation. To accomplish that I created the encrypted disks, lvm and partitions using ubuntu-server. Since 17.10 and 18.04 both have some kind of bug that when you reboot the system the keyboard defaults to US, I can't enter the password, my keyboard is Swedish with English as language and I use characters that do not exist in the US keyboard.

So, I started the ubuntu desktop installation, ran the try mode, select
the appropriate keyboard and tried to unlock the partitions.

On both cases it just hang without report any error.
With app "disks" I can select the cancel button but cryptsetup will hang forever, not even control-c helps.
I than try start the normal installation:
- with ubuntu 18.04 (daily 2018-01-15), the installation stops after I select the language and press continue... (it just hangs there!)
