No, we do not support entering passwords over VNC for security reasons.
Regarding serial console, that probably works if you change the calls to openvt

to something else that can tie the program to a serial console (getty?) But it is not something supported out-of-the-box.
Thanks for the repo links.
To others with this problem: the easiest workaround (apart from, obviously, connecting a screen & keyboard to the Pi and not using vncinstall) may be to install non-encrypted, then move the SD card to another computer which supports LUKS, clone the unencrypted partition, create an encrypted partition on the SD card, mount it and dd your cloned copy of the original partition back onto it.
There may be some juggling to do to get it to mount properly and present a password prompt for unlocking the encrypted partition on boot, but it was always my intention to have initrd kick off a limited dropbear ssh daemon to allow for unlocking the partition over the network so I would have needed to jump through some extra hoops anyway. Once I try this out, I will post here in case others need this solution.

Sounds like a lot of work, just to avoid plugging in a keyboard...

Just added support for unlocking through SSH in b7c87deada91e0ab80ece39c937b87171b4df708 You still need the keyboard during installation, don't see that as a priority to fix.
@maxnet Can you explain further how to setup the ssh access. Is it possible to define a fixed ip-address?
@tristan-k Add to cmdline.txt:
ipv4=192.168.88.88/255.255.255.0/192.168.88.1 ssh_authorized_key="your ssh pulic key"
Thanks! I did that but I'm getting a error:

This is how my cmdline.txt looks like: https://0b.tristank.de/?facb2bc210c2839b#16cTwC1mmFNbYzYI5Y0jrPslcUFVLefV+z89M9vwMk8=
Any suggestions? How to check if the ssh-key is added?
Boot an OS manually. cat /proc/cmdline
Verify the line is not truncated, which can happen if your cmdline.txt gets too long.
No it isn't truncated. I checked. Anything else? Could be related to the quotation marks? Which user should I login with?
Which user should I login with?
root
$ ssh -v tristank@192.168.1.17
which might indeed be your problem... Try: ssh root@192.168.1.17
Now it works, of course I have to use root :-/ Also a reminder for people editing the cmdline.txt on mac os x: don't use textedit.app, because it messes up the quotation marks. Thanks for your patience. One more question: "192.168.88.1" is the gateway address - right? Are there detailed instructions available for the network config of the cmdline.txt? http://elinux.org/RPiconfig doesnt go into that.
ipv4=192.168.88.88/255.255.255.0/192.168.88.1
Yes, last parameter is gateway. Options are handled by Berryboot. It is not a standard Linux parameter.

Thank you for your support!
When installing to a Raspberry Pi Model B+ with vncinstall enabled, encrypting the disk doesn't work (presumably because it tries to switch you to a secure text console to have you enter your password and there's no way to display that console when connected via VNC). On the VNC client, I see it pausing for a while at "Formatting data partition (ext4 nodiscard)" and then presumably the console request for the password times out and I see "Error Formatting data partition (ext4 nodiscard)".
Is there any workaround for this? I have serial console access to the Pi if that helps.
