ubuntu怎麼使用命令搜索軟體源中的軟體

E: Unable to locate package Kdevelop-dev 這是一個小夥伴安裝軟體包時出現的問題，其實LZ通過

sudo apt-get install name
1

安裝軟體的時候也會經常不記得一些依賴項的具體名字，畢竟腦容量有限，只能記得關鍵詞，下面就以Kdevelop為例。

sudo apt-cache search Kdevelop
//以下為輸出

可以對照自己的需求進行安裝了?(^?^*)按照上面輸出顯示：

sudo apt-get install Kdevelop

可能是ubuntu內核更新，包名也會經常改變，如果遇到這種sudo apt-get update後發現還是沒有找到對應的包名，那就使用sudo apt-cache search keyword
