篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了E: Unable to locate package gcc相关的知识，希望对你有一定的参考价值。

如果出现这种报错语句E: Unable to locate package xxx,我先直接给出解决措施：

更换软件源：

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

更换软件源之后需输入如下命令：sudo apt-get update，如果报错提示：

如提示代表签名错误，如无此报错提示，直接跳过即可，如有此报错输入命令更换签名：

40976EAF437D05B5 与 3B4FE6ACC0B21F32 对应报错信息中的数字根据实际情况输入

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 40976EAF437D05B5
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32

以上为解决措施

排查过程如下：

使用的是野火的开发板，开发板并不安装完整系统，所以gcc之类的工具需要自己安装

出现Unable to locate package gcc后我首先更换了软件源更换为阿里源，更换后sudo apt update时出现：

并且在出现如上报错的时候试图安装gcc也会出现签名错误

以上报错信息我才更换另一种软件源：

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

重新更换后再执行sudo apt update就不报错了

内容太长

随后我就正常安装了gcc

内容太长

以上总结出，安装gcc提示定位不到软件换源即可，同时注意签名信息报错

Unable to locate package错误解决办法

更改Ubuntu软件更新源文件 /etc/apt/sourse.list 之后，安装软件 sudo apt-get install gcc 出现错误提示 E: Unable to locate package

这是因为更新了软件源却没有应用，此时应该执行 sudo apt-get undata
