未找到 update-initramfs 命令

Question

如何按照其他地方描述的方式更新 initramfs以添加固件？

\n

对于 Debian 10，我得到一个command not found error. initramfs-tools已安装。

\n

root@pc:/home/.../linux-firmware/i915# update-initramfs -u\nbash: update-initramfs: command not found\nroot@pc:/home/.../linux-firmware/i915# apt install initramfs-tools\nReading package lists...

好的，再次用 google 搜索，找到了带有 live-update-initramfs 的 live-tools 包。然而，现在其他失败了。

在 sbin 中找到 update-initramfs。我不明白为什么它不在我的根路径中。然而，

# sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.19.0-5-amd64

完成了工作。
