问题
I used to use the picamera Python module, along with a Raspberry Pi Camera on Raspbian OS on my Raspberry Pi Model B.
Now I am running Ubuntu 14.04 LTS on a Raspberry Pi 2 Model B. However, I cannot use picamera anymore because I cannot enable the Raspberry Pi Camera. I cannot enable the Raspberry Pi Camera because I do not have Raspberry Pi firmware, so to speak. I actually have Ubuntu-rpi2 firmware.
Here's the output of uname -a:
Linux ubuntu 3.18.0-20-rpi2 #21-Ubuntu SMP PREEMPT Sun Apr 5 01:56:02 UTC 2014 armv71 armv71 armv71 GNU/Linux
Is it even possible to run Ubuntu and have the necessary RPi firmware to use the RPi Camera at the same time?

According to a post post by fo0bar » Fri Feb 27, 2015 3:49 am the userland firmware comes prebuilt via a PPA, the availability of the firmware is also stated at wiki.ubuntu.com. I dont have an rpi2 with ubuntu, but i would assume the PPA is already in your /etc/apt/sources.list. If not, see the ppa description on how to add it.
Then, try
sudo apt-get install libraspberrypi-bin libraspberrypi-dev
and be sure to enable the camera from
raspi-config
