我在 Ubuntu 20.04 上安装了 MySQL 服务器 8，我需要将其删除，然后才能安装5.6.51。我执行了 apt-get remove mysql-server 等，但它卡在了 64%，我停止并重新启动。我尝试安装 5.6.51，但它也卡住了。我在 /var/lib/dpkg/ 中执行了 sudo rm lock-frontend。现在我尝试删除 5.6.51 并进行全新安装，但删除显示“正在设置 mysql-community-server (5.6.51-1debian9)”
我甚至这样做了sudo apt autoremove- 它卡在了 93％：

Removing libgssdp-1.2-0:amd64 (1.2.3-0ubuntu0.20.04.1) ...
