我得到以下输出：
7 packages can be updated.
7 updates are security updates.

每当我连接到服务器时。而且我仍然看到这些软件包没有更新！我是root（sudo su）。
当sudo apt-get update我得到这个：
myserver@YHserver:~$ apt-get update

我应该怎么做才能更新它？这是安全更新，似乎很重要
我总是apt-get upgrade -y在“更新”之后运行。
我并没有删除锁定文件，而是按照此帖子的第二条评论：无法锁定管理目录（/ var / lib / dpkg /）是使用它的另一个过程吗？这没有帮助。我看不到持有“ apt”的过程
root 3004 0.0 0.0 9496 2260 pts/0 S+ 10:32 0:00 grep --color=auto apt-get

看来您有某种权限问题。
myserver@YHserver ...
在进行更新/升级时，您应该是root用户。看起来您是“ myserver”而不是root。您是通过ssh还是直接连接到计算机？（您需要启用“通过ssh root”）
请尝试执行patrick编写的命令并在此处报告结果
sudo apt-get update
sudo apt-get upgrade -y
如果这样做没有帮助，请尝试以下操作：
su
apt-get update
apt-get upgrade -y
我想到的另一种可能性是：您是否检查了远程升级？
sudo apt-get dist-upgrade
