不久前，我通过 GUI 更新程序安装了更新，然后出现了错误，类似于 linux-firmware 安装后脚本失败。老实说，我很高兴之后盒子仍然正常启动，所以我就放手了。但现在我正在安装从终端下载的 deb 包，我再次看到了与 linux-firmware 安装相关的错误。
我在日志中看到这个：
dpkg: dependency problems prevent configuration of linux-image-generic:
linux-image-generic depends on linux-firmware; however:
Package linux-firmware is not configured yet.
我在这里找到一篇帖子尝试一下sudo dpkg --configure -a，但错误是一样的。
以下是上述命令的完整日志：

Errors were encountered while processing:
linux-firmware

linux-generic
initramfs-tools

所以我猜问题在于mkinitramfs

我在 Dell Precision 5540 上运行 ubuntu，并按照本指南设置 FDEhttps://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019但我不知道这是否有关系。
看到固件配置问题有点可怕，所以我想解决它，以免将来导致更大的问题。
答案1
我也遇到过同样的问题，这个答案帮助过我。
我的/boot镜像很小，我需要清除一个以前的 Linux 镜像，以便腾出空间来initramfs-tools完成。使用 检查/boot并删除一个或多个旧镜像包apt purge。例如：
sudo apt purge linux-image-5.4.0-42-generic
这也会触发 initramfs-tools，因此我的下一步apt upgrade就清楚了。
autoremove升级后定期进行检查应保持/boot清晰：
sudo apt autoremove
对于那些固执的人：
sudo apt autoremove --purge
这是帮助文档描述更多细节。
