运行命令“psql”时出错错误：您必须至少安装一个 postgresql-client-<version> 软件包

Question

当我运行vagrant ssh 并成功登录然后尝试~$psql 命令我收到此错误Error: You must install at least one postgresql-client-<version> package. 我看到一个类似的问题here 我运行这个命令：

~$ sudo apt-get install postgresql-client

输出：

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

我也尝试了建议的修复，但没有奏效。

如何成功安装 postgresql 包？ 主要是如何让 $psql 命令给我图片中显示的所需输出？

（编辑）我尝试了第一个答案建议：

vagrant@precise64:~$ apt-get update
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
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?

然后尝试here提到的解决方案：

vagrant@precise64:~$ ps aux | grep apt
vagrant   1144  0.0  0.2  11676   948 pts/0    S+   18:59   0:00 grep --color=auto apt

我不明白，所以我不知道接下来会发生什么？

Answer 1

您在安装多个软件包时遇到了一些问题404 Not Found。

执行sudo apt-get update，然后重试安装。
