编译nvidia内核模块,无法满足的依赖关系

我下载了nvidia-kernel-source,然后尝试安装他的编译依赖

sudo aptitude build-dep nvidia-kernel-source -f,然后好像并没有正常解决变异依赖。

~/D/n/nvidia-graphics-drivers-440.100 $ dpkg-buildpackage -B -j10
dpkg-buildpackage: info: source package nvidia-graphics-drivers
dpkg-buildpackage: info: source version 440.100-1~bpo10+1
dpkg-buildpackage: info: source distribution buster-backports
dpkg-buildpackage: info: source changed by Luca Boccassi <bluca@debian.org>
dpkg-buildpackage: info: host architecture amd64
 dpkg-source --before-build .
dpkg-checkbuilddeps: error: Unmet build dependencies: debhelper-compat (= 13)
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

所以,debhelper-compat到底是个啥

我就是想安装显卡驱动。。。

好了,现在的问题是显卡好像不能够正常工作
