今天给我 NAS 换上了 RTX 2060，安装 nv 专有驱动的时候报错没有 gcc，于是考虑安装 build-essential，结果报错：

madray@NAS:~$ sudo apt install build-essential

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 build-essential : Depends: libc6-dev but it is not going to be installed or
                            libc-dev
 libstdc++-12-dev : Depends: libc6-dev (>= 2.23-1~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

首先尝试 apt upgrade，无果；然后尝试手动安装 libc6-dev：

madray@NAS:~$ sudo apt install libc6-dev

然后重新依次尝试安装 libc6-dev、build-essential 就成功了。
