我得到这个输出：
7 packages can be updated.
7 updates are security updates.
Last login: Tue Apr 19 10:04:51 2016 from 10.0.0.199
每当我连接到我的服务器时。我仍然看到这些包没有更新！我是 root ( sudo su)。
当我sudo apt-get update得到这个：
myserver@YHserver:~$ apt-get update

我该怎么做才能更新它？这是安全更新，而且似乎很重要
我总是追求apt-get upgrade -y“更新”。
我没有删除锁文件并按照这篇文章的第二条评论操作： 无法锁定管理目录（/var/lib/dpkg/），是否有另一个进程正在使用它？ 这没有帮助。我看不到持有“apt”的进程
root 3004 0.0 0.0 9496 2260 pts/0 S+ 10:32 0:00 grep --color=auto apt-get
root@YHserver:/home/myserver# kill -9 3004
bash: kill: (3004) - No such process
root@YHserver:/home/myserver# kill -9 2260
bash: kill: (2260) - No such process
root@YHserver:/home/myserver# kill -9 9496
bash: kill: (9496) - No such process
答案1
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denie d)
E: Unable to lock directory /var/lib/apt/lists/
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
这看起来就像您遇到了某种权限问题。
myserver@YHserver ...
更新/升级时，您应该是 root。看起来您是“myserver”，而不是 root。您是通过 ssh 还是直接连接到机器？（您需要启用“通过 ssh 的 root”）
请尝试执行 patrick 编写的命令并在此报告结果
sudo apt-get update
sudo apt-get upgrade -y
如果这没有帮助，请尝试以下操作：
su
apt-get update
apt-get upgrade -y
我想到了一个另一种可能性：你检查过 dist-upgrades 吗？
sudo apt-get dist-upgrade
答案2
尝试这个
sudo apt-get update;sudo apt-get upgrade -y
我经常使用它，如果有可用的更新，它会更新所有已安装的软件包
