我反复尝试了许多我能找到的答案。它们都导致相同的错误。我不确定原因，但感觉状态仍处于从 6.2.0-26 升级到 6.2.0-27 的中间阶段。但这完全是我的猜测。我不知道为什么会处于这种状态，我尝试遵循的每个文档都试图清除旧内核，但都失败了，因为似乎虽然旧内核可见，但它们并未安装？
我尝试按照软件更新程序中的建议，通过更改 /etc/initramfs-tools/initramfs.conf 中的 COMPRESS=xz，但可用空间也有所不同。

从目录列表可以看出。启动空间主要由一个无法删除的文件使用，initrd.img-6.2.0-26-generic 使用了 /boot 目录中 258M 中的 225M。我无法删除唯一活动的内核，因此无法按照删除额外内核的步骤操作。请不要将其关闭为重复项。
启动分区是使用 Ubuntu 的默认安装设置创建的。更新始终从软件更新程序应用。dpkg 显示一堆内核，但使用 remove 命令显示它们未安装，因此无法删除。
当我打开“磁盘”应用程序时，我甚至看不到 /boot 分区。只有 /boot/efi 仍有大量空间，还有其他未挂载的分区？
