我全新安装了 Ubuntu 12.04.3 LTS
毁灭cat /etc/apt/sources.list
显示：
deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu precise-security main restricted universe multiverse
但如果我跑，sudo apt-get update && sudo apt-get install mlocate locate
我就会
Package locate is a virtual package provided by:
locate:i386 4.4.2-4ubuntu1 [Not candidate version]
E: Package 'mlocate' has no installation candidate
E: Package 'locate' has no installation candidate
请帮忙！我从来没有意识到我有多么依赖 find 命令。
欢呼吧，保罗

答案1
创建/var/lib/dpkg/arch包含以下文本的文件：
amd64
i386
然后执行，sudo apt-get update现在您可以重新开始安装。
答案2
经过进一步调查，结果发现该功能已被托管公司禁用。
默认情况下，mlocate 未安装，如果默认安装，则禁用。原因是 cron 任务和 IO 负载会放在服务器上，这可能会影响同一主机上的其他服务器。IO 是主机速度变慢的最大原因，这就是我们相当严格的原因。我们更愿意鼓励人们使用 find 命令来查找内容，例如 find / -iname "某名“
当试图弄清楚这一点时，我首先求助于谷歌，但我无法找到有关此问题的任何有用信息。
我已将此添加为答案，以便希望将来在 Google 上搜索“无法安装定位”的人能够知道先询问他们的托管公司！
