我在Ubuntu 17.04上。

长话短说，在与MariaDB搏斗了一段时间之后，我遵循了一些可疑的建议，关于如何从家庭服务器中完全删除MySQL和MariaDB。现在，我无法重新安装mysql-server。我尝试时遇到此错误：

Failed to stop mysql.service: Unit mysql.service not loaded.
invoke-rc.d: initscript mysql, action "stop" failed.
invoke-rc.d returned 5
There is a MySQL server running, but we failed in our attempts to stop it.
Stop it yourself and try again!

因此，我使用来检查服务sudo service --status-all | grep mysql，而且肯定...

[ - ]  mysql

问题是，当我尝试时sudo service mysql status，我得到

Unit mysql.service could not be found.

我真的很想安装MySQL并重新进行工作，而无需执行全新安装！任何帮助表示赞赏。

主机操作系统是Ubuntu 19.10。我已成功使用启动FreeIPA 容器docker run，但我想让它在 compose 中工作。当我运行时docker-compose up，freeipa 崩溃并出现以下错误：

IPv6 stack is enabled in the kernel but there is no interface that has 
::1 address assigned. Add ::1 address resolution to 'lo' interface. 
You might need to enable IPv6 on the interface 'lo' in sysctl.conf.

我当前的配置：

freeipa:
        image: freeipa/freeipa-server
        command:
            [
                "--realm=${ROOT_DOMAIN}",
                "--ds-password=${LDAP_USER_PASSWORD}",
                "--admin-password=${LDAP_ADMIN_PASSWORD}",
                "-U",
            ]
        hostname: ${FREEIPA_DOMAIN}
        container_name: freeipa
        restart: unless-stopped
        labels:
            - "traefik.enable=true"
            - "traefik.http.routers.freeipa.rule=Host(`${FREEIPA_DOMAIN:?Domain for Freeipa must be set!}`)"
            - "traefik.http.routers.freeipa.entrypoints=secure" …
