WSL環境でDockerが動作しなくなったの抜粋版です
うっかりapt update && sudo apt -y upgradeしてしまったらWSL環境でDockerが動作しなくなった
hello-worldしてみた
$ docker run hello-world
docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: running exec setns process for init caused \"exit status 23\"": unknown.
ERRO[0001] error waiting for container: context canceled
戻せそうなバージョンを確認する
apt show [インストールパッケージ名] -aでパッケージのインストールできるバージョンの一覧を取得できる
$ sudo apt show docker.io -a
一旦削除して、バージョンを指定して再インストールする
$ sudo apt remove docker.io
$ sudo apt -y install docker.io=17.12.1-0ubuntu1
hello-worldも動いた
$ docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
