Docker unlinkat device

`unlinkat` system call is used to remove a file or directory from a directory. However, if you are receiving an error related to `unlinkat` in Docker, it is likely due to a problem with the Docker storage driver.

One possible solution is to stop and remove all running Docker containers, then stop the Docker service and remove the Docker storage driver files, and then start the Docker service and recreate the containers.

Here are the steps to do this:

1. Stop and remove all running Docker containers:

docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

2. Stop the Docker service:

sudo systemctl stop docker

3. Remove the Docker storage driver files:

sudo rm -rf /var/lib/docker

4. Start the Docker service:

sudo systemctl start docker

5. Recreate the Docker containers as needed.

Note: Please be careful while deleting the files related to Docker storage driver as it may lead to data loss.
