libgcc-s1 在 Ubuntu 18.04 arm64 上破坏了 gcc-9

不知何故，gcc-7 和 gcc-9 都从我的 Ubuntu 18.04.4 arm64 系统中删除了，我们需要它们来编译我们的代码。对我来说，似乎自 2020 年 4 月 5 日起对 libgcc-s1 的更新破坏了 18.04 中对 arm64 的兼容性。有人有解决方案或解决方法吗？

当我尝试重新安装它们时，我得到：

$ sudo apt-get install gcc-9 g++-9 gcc-7 g++-7

如果我尝试安装这些依赖项，我会得到：

$ sudo apt install libstdc++-9-dev libgcc-9-dev libstdc++-7-dev libgcc-7-dev

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

我已检查没有被保留的软件包，并且未发现 libgcc-s1 的可用更新。我正在使用 repo ubuntu-toolchain-r/test，我的 libgcc-s1 是版本 10-20200405-0ubuntu1~18.04。

更新 07/08：我们更新了我们的代码以兼容 gcc10 g++10，并且能够成功安装它们。

我在安装 openjdk13 时遇到同样的问题：

The following packages have unmet dependencies:
 openjdk-13-jre-headless : Depends: libgcc-s1 (>= 4.0) but it is not installable

在安装 openjdk 之前，我必须从 Dockerfile 中的 URL 安装 gcc-10-base 和 libgcc-s1：

RUN curl -sLO http://ftp.fr.debian.org/debian/pool/main/g/gcc-10/gcc-10-base_10-20200418-1_amd64.deb && dpkg -i gcc-10-base_10-20200418-1_amd64.deb
RUN curl -sLO http://ftp.fr.debian.org/debian/pool/main/g/gcc-10/libgcc-s1_10-20200418-1_amd64.deb && dpkg -i libgcc-s1_10-20200418-1_amd64.deb

首先，在页面中添加链接https://packages.debian.org/sid/arm64/gcc-9-base/download 到 /etc/apt/sources.list 其次，运行apt --fix-broken install不带任何包名称的程序，重新启动并重新尝试安装您的包。
