If docker / containerd not running

Most often this problem occurred by file corruption.

Runninc docker containers:

docker ps

Here’s how to repair Docker+containerd:

• Stop Docker and containerd:
  systemctl stop docker containerd
• Cleanup containerd data directory (Docker will regenerate it at startup if needed):
  rm -rf /var/lib/containerd/
• Find Docker’s database files – one of them (most often local-kv.db) corrupted in your system:
  find /var/lib/docker -type f -size -5M -name '*.db' | grep -v overlay2
  – will output something like:
  /var/lib/docker/containerd/daemon/io.containerd.metadata.v1.bolt/meta.db
  /var/lib/docker/volumes/metadata.db
  /var/lib/docker/network/files/local-kv.db
  /var/lib/docker/builder/fscache.db
  /var/lib/docker/buildkit/snapshots.db
  /var/lib/docker/buildkit/metadata.db
  /var/lib/docker/buildkit/cache.db
• Simply rename this file to .bak:
  mv /var/lib/docker/network/files/local-kv.db{,.bak}
• Start Docker:
  systemctl start docker
