E: Unable to locate package Kdevelop-dev 这是一个小伙伴安装软件包时出现的问题，其实LZ通过
sudo apt-get install name安装软件的时候也会经常不记得一些依赖项的具体名字，毕竟脑容量有限，只能记得关键词，下面就以Kdevelop为例。
sudo apt-cache search Kdevelop
//以下为输出

可以对照自己的需求进行安装了♪(^∇^*)按照上面输出显示：
sudo apt-get install Kdevelop可能是ubuntu内核更新，包名也会经常改变，如果遇到这种sudo apt-get update后发现还是没有找到对应的包名，那就使用sudo apt-cache search keyword
是不是一个比较有用的小技巧呢O(∩_∩)O哈哈~
