Kubuntu setup / install encryption keyfile creation failure when setting up luks

[Jason Straight]

While setting up kubuntu 13.10 and attempting to manually partition free space as encrypted volume, it fails with "keyfile creation failure"

I've verified that creating a luks partition does work from the server installer.

Me too. Kubuntu 14.04.1 64bit

Seems to be an old (>1 year) problem:

It's a GUI problem in Kubuntus Installer. Here is a workaround:

1) click the radiobutton for the guided install with encryption and enter your password.
2) select manual partitioning
3) create your /boot partition with your desired filesystem and a physical crypto volume. on which you create your root filesystem

the password fields seem to be connected to the guided install but they are used globally. They seem greyed out but thats just a visual problem. The Password field is used whether you entered something or not.

please correct this GUI Design flaw ASAP.

#7
With this workaround I can't create an encrypted SWAP partition.

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
