这种情况已经持续了几个星期。除了这个之外，其他所有软件包升级都没有问题，但我不确定是什么原因导致的，也不知道该如何调试。

首先停止 mysql。然后运行更新。然后它应该可以工作。
编辑。在运行更新之前，请尝试
sudo service mysql stop
然后
sudo apt-get upgrade
然后你可以做
service mysql start
如果仍然有问题，那么您可能需要检查“sudo service mysql stop”命令是否没有留下任何 MySQL 进程。您可以使用以下命令检查进程。解释 ps 的输出超出了本答案的范围 ps -ef |grep mysql
但为了完整性，以下是我在 MySQL 运行时得到的结果
root@control:~# ps -ef |grep mysql
root 1304 1 0 Oct24 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe
mysql 2568 1304 6 Oct24 ? 10:55:04 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql/ --plugin-dir=/usr/lib/mysql/plugin --user=mysql --log-error=/var/lib/mysql/mysql-error.log --open-files-limit=65535 --pid-file=/var/lib/mysql/mysql.pid --socket=/var/run/mysqld/mysqld.sock
root 4492 23102 0 11:32 pts/3 00:00:00 grep --color=auto mysql
... 当 MySQL 停止时...
root@control:~# ps -ef |grep mysql
root 4492 23102 0 11:32 pts/3 00:00:00 grep --color=auto mysql

我遇到了完全相同的问题，唯一能解决它的方法就是杀死 mysql：
ps aux | grep mysql
mysql 1325 10.3 3.3 2216444 309324 ? Sl Sep24 22:38 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib/mysql/plugin --user=mysql --log-error=/var/
lib/mysql/ecom-mysql.err --pid-file=/var/lib/mysql/ecom-mysql.pid --socket=/var/run/mysqld/mysqld.sock --port=3306
sudo kill -9 1325
sudo apt-get update && sudo apt-get dist-upgrade

我在 Debian Wheezy 上也遇到了这个问题。我所能做的就是手动终止 mysql 进程，运行我的 apt-get update，这样就没问题了。
