显然，列表中没有mysql这样的依赖项：
# apt depends fpart
fpart
Depends: libc6 (>= 2.4)
Depends: rsync (>= 3.1.1)
Depends: sudo (>= 1.8.12)
造成这种情况的原因可能是什么？也许是 MySQL 安装未完成？

因此# ps aux | grep -i mysql | grep -v grepMySQL 没有运行
答案1
看起来 MySQL 升级过程失败了。
如果您修改了 MySQL 系统用户，则升级可能会失败，因为无法通过 MySQL 套接字进行身份验证。
另一种可能性是您的 MySQL 服务器没有运行，因此升级过程无法连接到服务器。
