Question

when I run vagrant ssh and login successfully then try ~$psql command I get this error Error: You must install at least one postgresql-client-<version> package. I saw a similar question here and i run this command:

~$ sudo apt-get install postgresql-client

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

I tried the suggested fix missing too but didn't work.

how can I install a postgresql package successfully? and mainly how can I get $psql command to give me the desired output showed in the picture?

(Edit) I tried the first answe suggestion:

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?

Then tried the solutions mentioned here :

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

I don't understand so i dont know whats next?

Answer 1

您似乎在安装多个软件包404 Not Found时遇到了一些麻烦。

执行sudo apt-get update，然后重试安装。
