问题
操作容器应该是属于服务器开发同学的常规操作，经常我们会遇到系统缺少对应的工具的情况，比如我们进入容器后，想使用 vim 修改某个文件，但是发现该容器没有安装 vim 工具。这个时候，一般都需要自己手动安装，比如在 unbuntu 系统中，可以使用 apt-get 包管理命令。
但是，执行 apt-get install vim 命令时，提示没有仓库记录，因此，需要先更新包管理仓库列表，也就是执行 apt-get update 命令，但是遇到了如下报错信息：
root@al-bj-boom-hb-backstage-01:/etc/nginx# apt-get update Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB] Err:1 http://security.debian.org/debian-security buster/updates InRelease Couldn't create temporary file /tmp/apt.conf.IRqbCz for passing config to apt-key Get:2 http://deb.debian.org/debian buster InRelease [122 kB] Err:2 http://deb.debian.org/debian buster InRelease Couldn't create temporary file /tmp/apt.conf.Afcu25 for passing config to apt-key Get:3 http://deb.debian.org/debian buster-updates InRelease [51.9 kB] Err:3 http://deb.debian.org/debian buster-updates InRelease Couldn't create temporary file /tmp/apt.conf.fztemY for passing config to apt-key Reading package lists...

解决
解决方法总结下来也非常简单，执行下面的命令就可以了：
chmod 777 /tmp
执行后，再执行 apt-get update 命令，终于成功啦！
执行过程如下：
root@al-bj-boom-hb-backstage-01:/etc/nginx# chmod 777 /tmp root@al-bj-boom-hb-backstage-01:/etc/nginx# apt-get update Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB] Get:2 http://deb.debian.org/debian buster InRelease [122 kB] Get:3 http://security.debian.org/debian-security buster/updates/main amd64 Packages [308 kB] Get:4 http://deb.debian.org/debian buster-updates InRelease [51.9 kB] Get:5 http://deb.debian.org/debian buster/main amd64 Packages [7906 kB] Get:6 http://deb.debian.org/debian buster-updates/main amd64 Packages [15.2 kB] Fetched 8230 kB in 4min 19s (31.7 kB/s) Reading package lists... Done
整体过程截图如下：

更新完 apt-get 的工具库列表，我们就可以正常安装和使用 vim 工具啦！实时证明：确实好用。
