Ubuntu 18.04，将 gcc 从 8.4 降级到 8.3

我正在使用一些略微过时的构建工具，这些工具无法与 gcc 8.4 配合使用；它们识别的最新版本是 gcc 8.3。我正在使用 Ubuntu 18.04，运行时apt list gcc-8 --all-versions似乎 gcc 8.3 不再存在于 bionic 存储库中。我该如何降级 gcc-8？

编辑：

我尝试从安装 gccjonathanf 的 gcc 反向移植像这样：

sudo add-apt-repository ppa:jonathonf/gcc
sudo apt install gcc-8=8.3.0-19ubuntu1~18.04.york0

但是，缺少依赖项：
