我在安装 Community DisplayLink 驱动程序时遇到问题
https://github.com/AdnanHodzic/displaylink-debian
当 evdi 包必须在内核上构建时，我特别失败
我使用的是 20.04 和内核 5.13
以下是额外的日志输出：

安装后我遇到了同样的问题DisplayLink 驱动程序经过一些内核更新后，适用于 Dell D3100 扩展坞。
ERROR (dkms apport): binary package for evdi: 1.10.1 not found
通过 Aptitude 安装 DKMS 后，一切就解决了。
sudo aptitude install dkms
希望能帮助到你。
