Ubuntu 20.04 linux-firmware 安装错误（mkinitramfs 失败）

Question

不久前，我通过 GUI 更新程序安装了更新，并收到了一个错误，类似于 linux-firmware 安装后脚本失败。老实说，我很高兴盒子在那之后仍然可以正常启动，所以我就放弃了。但现在我正在安装从终端下载的 deb 包，我再次看到与 linux-firmware 安装相关的错误。

我在日志中看到了这一点：

dpkg: dependency problems prevent configuration of linux-image-generic:
linux-image-generic depends on linux-firmware; however:
Package linux-firmware is not configured yet.

我在这里找到了一个帖子来尝试sudo dpkg --configure -a，但错误是相同的。

以下是上述命令的完整日志：

所以我猜问题是mkinitramfs

Error 24 : Write error : cannot write compressed block 
E: mkinitramfs failure cpio 141 lz4 -9 -l 24

我在 Dell Precision 5540 上运行 ubuntu，并按照本指南https://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019设置 FDE，但我不知道这是否与此有关。

看到固件配置问题有点可怕，所以我想解决它，这样它就不会在将来导致更大的问题。

Answer 1

我也遇到了同样的问题，这个答案对我有帮助。

我的/boot很小，我需要清除以前的 Linux 映像之一才能腾出空间来initramfs-tools完成。检查/boot并删除一个或多个旧映像包apt purge。前任：

sudo apt purge linux-image-5.4.0-42-generic

这也会触发 initramfs-tools，所以我的下一步apt upgrade很清楚。

autoremove升级后执行定期操作应/boot清楚：

sudo apt autoremove

对于顽固的人来说：

sudo apt autoremove --purge

这是描述更多细节的帮助文档。
