Update / Pulling image results in "no space left on device"

[CozMedic]

I was having unifi-specific issues and in troubleshooting I thought to pull down the latest container. I came back here to follow your instructions using updatedocker.sh but I received the following in the terminal:

fc6a701a0672: Pull complete
4e067bf34ebb: Verifying Checksum
4e067bf34ebb: Download complete

At the end all I was left with was:

Hitting continue, I pruned leftover images and ran the installation script again. The checks worked as expected and it used the newer image. Not sure if I really ran out of space and if so, if there's a way to implement a check that will better prepare for the scenario. I only have this container on my Gold+ and seemingly had two "stale" images (after pulling the latest).

The error does say no space left on the device. I'm not sure what else can be done. Ideas?

In my case, the sudo $DOCKER image prune line coming before sudo docker-compose up -d would have stopped the issue from occurring, but I'm surprised I ran out of storage since Unifi controller is the only image I run. Have you ran into a similar issue before?
