每次我在运行GNU/Linux Debian Buster 10. 0 的Dell PowerEdge T20 服务器上更新我的initramfs映像（-s）时update-initramfs，我都会收到这些警告。有解决办法吗？

Answer 1

对于一般解决方案，apt-file是您解决Possible missing firmware...警告的方法。例如：

apt-file search bxt_dmc

firmware-misc-nonfree: /lib/firmware/i915/bxt_dmc_ver1.bin
firmware-misc-nonfree: /lib/firmware/i915/bxt_dmc_ver1_07.bin

显示软件包firmware-misc-nonfree提供了缺少的固件。

安装firmware-linux包解决了这个问题，因为firmware-linux取决于firmware-linux-nonfree哪个取决于firmware-misc-nonfree.

详细说明：

添加non-free到您的/etc/apt/sources.list：

deb http://deb.debian.org/debian buster main contrib non-free
deb http://deb.debian.org/debian-security/ buster/updates main contrib non-free
deb http://deb.debian.org/debian buster-updates main contrib non-free

安装apt-file：

sudo apt update
sudo apt install apt-file
sudo apt-file update

Debian: apt-file

Answer 2

看来答案一直在我眼前。

我终于找到了正确的 package: firmware-linux，它安装了所有丢失的固件。安装它：

sudo apt-get install firmware-linux

这些警告可能会在之后消失。

你可以从这里下载它们

并将下载的文件复制到此路径： /lib/firmware/i915/

然后 update-initramfs -u -k all

（然后sudo apt-get update -y）
