How to fix failed to create containerd task: failed to create shim task in Docker

# Check containerd status
sudo systemctl status containerd

# If not running, start it
sudo systemctl start containerd

# Check for errors in the logs
sudo journalctl -u containerd -n 50 --no-pager

# Restart both services
sudo systemctl restart containerd
sudo systemctl restart docker

# Verify both are running
sudo systemctl status containerd docker

# Stop all running containers
docker stop $(docker ps -q) 2>/dev/null

# Remove all stopped containers
docker container prune -f

# Clean up unused images and networks
docker system prune -f

# For more aggressive cleanup (removes unused volumes too)
docker system prune -a --volumes -f

# Check available disk space
df -h /var/lib/docker
df -h /var/lib/containerd

# Check for filesystem errors (if possible)
sudo touch /var/lib/docker/.test && sudo rm /var/lib/docker/.test

# Check versions
docker version
containerd --version
runc --version

# If versions are mismatched after an update, consider:
# 1. Update all components together
sudo apt update && sudo apt upgrade docker-ce docker-ce-cli containerd.io

# 2. Or rollback to a known working version
# (check your package manager for available versions)

# Check SELinux status (RHEL/CentOS/Fedora)
getenforce

# Temporarily set to permissive for testing
sudo setenforce 0

# Check AppArmor status (Ubuntu/Debian)
sudo aa-status

# Check Docker's AppArmor profile
sudo aa-status | grep docker

# Remove the existing image
docker rmi <image-name>

# Pull a fresh copy
docker pull <image-name>

# Try running the container again
docker run <image-name>
