[Solved] Let’s Encrypt Could not bind TCP port 80 because it is already in use by another process on this system (such as a web server)

更新コマンドが失敗する場合

環境に合わせて「–apache」や「–nginx」オプションを追加してあげる

このブログのWebサーバはNginなので「–nginx」を追加した

/var/lib/snapd/snap/bin/certbot renew --no-self-upgrade --nginx --deploy-hook "systemctl restart nginx"

# /var/lib/snapd/snap/bin/certbot renew --nginx --no-self-upgrade --deploy-hook "systemctl restart nginx"
