我无法在我的 ubuntu 服务器上安装几乎所有东西。它从 3 天前我尝试在服务器上安装 MySQL 时开始。当我尝试安装 MySQL 时，我提示我输入密码，输入密码并继续后，它给了我以下屏幕：
┌───────────────────────Configuring mysql-server-5.5─────────────────────────┐
│ Unable to set password for the MySQL "root" user │
│ │
│ An error occurred while setting the password for the MySQL │

然后我点击了“确定”。我得到了错误：

今天当我尝试安装 pptpd 时，我遇到了同样的错误...所以我认为错误是由于 MySQL 服务器安装失败而开始的。
我非常努力地尝试安装 MySQL，并查看了互联网上的所有解决方案，但仍然无法安装它。
我已尝试以下所有方法，但问题仍然存在：
dpkg -S etc/mysql
aptitude purge mysql-server --purge-unused
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/mysql
sudo dpkg --configure -a
sudo apt-get update
我也尝试过这个，但没有成功：
sudo apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5
sudo dpkg -i mysql-5.6.13-debian6.0-i686.deb
sudo apt-get install mysql-server
有人能帮帮我吗？提前谢谢了。

您必须更改postrm以清除包：
打开文件
sudo nano /var/lib/dpkg/info/mysql-server-5.5.postrm查找代码片段
if [ -n "`$MYADMIN ping 2>/dev/null`" ]; then stop_server sleep 2 fi并注释掉这一行
stop_serverif [ -n "`$MYADMIN ping 2>/dev/null`" ]; then # stop_server sleep 2 fi保存文件并再次清除
sudo apt-get purge mysql-server-5.5
此后，您就修复了系统，可以再次安装和卸载软件包。
