"Docker critical image disk utilization" - running out of space

I am running into this issue,  any thoughts, anything I should try?



Update
I am updating my Jupypter hub with a 4GB image, which downloads fine and then fails.

Notification pops up

Docker critical image disk utilization: 06-03-2023 15:26

Alert [TOWER] - Docker image disk utilization of 90%
Docker utilization of image file /mnt/user/system/docker/docker.img
