意外地将libstdc++6:amd64从12.1.0-2 ubuntu1~22.04降至10-20200411-0ubuntu1

Question

为什么要获得gcc/g++的调试符号，我不小心通过运行以下命令将libstdc++6:i386和libstdc++6:amd64从12.1.0-2 ubuntu1~22.04降至10-20200411-0ubuntu1。

wget http://archive.ubuntu.com/ubuntu/pool/main/g/gcc-10/libstdc++6_10-20200411-0ubuntu1_i386.deb
sudo dpkg -i libstdc++6_10-20200411-0ubuntu1_i386.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/g/gcc-10/libstdc++6_10-20200411-0ubuntu1_amd64.deb
sudo dpkg -i libstdc++6_10-20200411-0ubuntu1_amd64.deb

后面跟着错误，比如

dpkg: warning: downgrading libstdc++6:i386 from 12.1.0-2ubuntu1~22.04 to 10-20200411-0ubuntu1

现在许多命令不再工作了，特别是apt。

sudo apt-get update
apt-get: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /lib/x86_64-linux-gnu/libapt-private.so.0.0)

为了子孙后代的缘故，我在这里做了些什么来解决我的问题

获取库的包，我意外地降低了它们的级别，然后安装了它们。

wget http://security.ubuntu.com/ubuntu/pool/main/g/gcc-12/libstdc++6_12.1.0-2ubuntu1~22.04_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/main/g/gcc-12/libstdc++6_12.1.0-2ubuntu1~22.04_i386.deb
sudo dpkg -i libstdc++6_12.1.0-2ubuntu1~22.04_amd64.deb
sudo dpkg -i libstdc++6_12.1.0-2ubuntu1~22.04_i386.deb

在某些情况下，需要使用--force-all选项垫。
