在ubuntu22.04上安装gcc7

Question

我想在Ubuntu 22.04上安装gcc-7。

我用：

sudo apt-get install gcc-7 g++-7

但是得到了一个错误：

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package g++-7 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Package gcc-7 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'gcc-7' has no installation candidate
E: Package 'g++-7' has no installation can

我怎么把它安装在我的机器上？

亲切的问候

谢谢@Knud Larsen的解决方案。

我也遇到了同样的问题，我需要使用旧版本的distcc服务器。客户端系统，一个薄弱的工业PC不能更新。

所以解决办法很简单，我没有想过，但它有效。为了记录在案，我补充说：

deb [arch=amd64] http://archive.ubuntu.com/ubuntu focal main universe

到/etc/apt/sources.list .列表和

ran：apt update; apt install g++-7
