[SOLVED] Different kernel versions use different keyboard layouts when inputting FDE pass

I have keels 4.2.0-16 and 4.2.0-34 installed on Lubuntu 15.10 system with full disk encryption.

When I boot up with 4.2.0-34 and get to the FDE pass prompt, the pass is input using US keyboard layout, but when I boot up with 4.2.0-16 the pass is input using a different keyboard layout.

During the installation of Lubuntu I choose a non-US keyboard layout and after the installation both keels would use the non-US keyboard layout I chose. However, after the install in Language Support I chose English to "apply system-wide", but this seems to have been applied only to the 4.2.0-34 that I booted up with when I changed the settings. At least that's what I think happened.

So, how would I change the keyboard layout on 4.2.0-16 to US one, too?

EDIT: Well, this was a stupid question. Removing, purging and then reinstalling `linux-headers-4.2.0-16 linux-headers-4.2.0-16-generic linux-image-4.2.0-16-generic linux-image-extra-4.2.0-16-generic` did the trick.
