如何找寻deb包
第一种方法
sudo apt-get install libuuid1 之后会在路径 /var/cache/apt/archives下有对应的deb包，例如：
ubuntu@VM-0-7-ubuntu:/var/cache/apt/archives$ ls
libuuid1_2.27.1-6ubuntu3.6_amd64.deb lock partial
1
2
第二种方法
还可以利用另一种方式，输入命令查询他的包信息：
apt-cache show libuuid1
得到如下信息：

Description-en: Universally Unique ID library
The libuuid library generates and parses 128-bit Universally Unique
IDs (UUIDs). A UUID is an identifier that is unique within the space
of all such identifiers across both space and time. It can be used for
multiple purposes, from tagging objects with an extremely short lifetime
to reliably identifying very persistent objects across a network.
.
See RFC 4122 for more information.

其中有一行：
Filename: pool/main/u/util-linux/libuuid1_2.27.1-6ubuntu3_amd64.deb
之后可以用如下地址下载：
http://archive.ubuntu.com/ubuntu/pool/main/u/util-linux/libuuid1_2.27.1-6ubuntu3_amd64.deb
其实就是在Filename前加入：“http://archive.ubuntu.com/ubuntu/”
