Picamera install: Failed building wheel for picamera

Hi,
I'm stuck trying to install picamera
Env: ubuntu mate 20.04 32 bit, Pi 4

running pip3 install picamera gives error below.

I know at a hardware level the camera works. I tried the picamera-streaming-demo via snap, and it worked fine.

My ultimate goal is to ros development with the picamera.

Any help is appreciated!

buntu@pi:/usr/lib$ pip3 install picamera

I'm having the same problem. Using Ubuntu Mate 20.04 on a Raspberry Pi 4B.
raspistill and raspivid are working fine.

I tried sudo pip installing picamera but got the same error as above.
