Does the shift switch occur, or is Caps Lock completely broken?

In any case, this is a very old bug, it's kernel related and has to do
with UTF-8 encoding and certain character sets.

https://bugs.launchpad.net/ubuntu/+source/console-setup/+bug/425704
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=514464

The upstream debian bug has more detail.

The tl;dr version is that it's apparently not so trivial to fix. If
you connect to your server via SSH from a desktop, caps lock light
will work. If you hit CTRL-ALT-F2 on a Debian desktop system, you'll
find this ALSO occurs on the TTY (Text Console). It's not an Ubuntu
bug, it's a Kernel bug from way back that likely will never be fixed.
The GUI environment uses a different mechanism to address/map the keys
and functions on a keyboard, so the light works there. But in a pure
console, it just ain't gonna happen.
