当试图在我的20.04 LTS主机上安装nvidia专有驱动程序时，我遇到了一个在使用DKMS时它不会安装的问题。它抱怨gcc的内核版本(9.3.0)和gcc版本(9.4.0)之间的错误。问题发生在升级到最新的内核版本之后。在运行gcc版本时，它报告了9.4.0，而apt显示gcc报告了9.3.0。

gcc --version
gcc (Ubuntu 9.4.0-1ubuntu1~20.04) 9.4.0

apt show gcc
Package: gcc
Version: 4:9.3.0-1ubuntu2

lsb_release -a
LSB Version:    core-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.4 LTS
Release:    20.04
Codename:   focal

uname -a
Linux xenon 5.4.0-104-generic #118-Ubuntu SMP Wed Mar 2 19:02:41 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

在我看来，问题似乎是gcc的包是9.3.0，如apt所示，但报告9.4.0。

有什么建议吗？

正如在一篇评论中所说，我看不到老gcc的版本。我的sources.list文件可能是问题所在吗？看起来是这样的：

我能够通过暂时将gcc降级到9.3来绕过这个问题，然后我可以编译nVidia驱动程序：

使用智能，我降级，然后持有g++-9，它会自动保存它的相关包。如果你喜欢的话，你也可以使用“apt-标记保持”。

下面是在我的系统中暂时保持状态的包：

[HOLD, DEPENDENCIES] cpp-9:amd64 9.3.0-10ubuntu2
[HOLD, DEPENDENCIES] g++-9:amd64 9.3.0-10ubuntu2
[HOLD, DEPENDENCIES] gcc-9:amd64 9.3.0-10ubuntu2
[HOLD, DEPENDENCIES] gcc-9-base:amd64 9.3.0-10ubuntu2
[HOLD, DEPENDENCIES] libasan5:amd64 9.3.0-10ubuntu2
[HOLD, DEPENDENCIES] libgcc-9-dev:amd64 9.3.0-10ubuntu2
[HOLD, DEPENDENCIES] libstdc++-9-dev:amd64 9.3.0-10ubuntu2

一旦用gcc 9.4编译了系统的新内核(即使用：

cat /proc/version

检查)或者当您不再需要重新编译nVidia驱动程序时，您应该能够释放已保存的9.4GCC升级，并将它们安装在您的系统上。

编辑:根据您的请求，这里有一个/etc/apt/ request。列表可以使用：
