受最近 CVE 安全请求更新内核的启发，我尝试使用sudo apt-get update && sudo apt-get install linux-generic此更新内核，但失败了。因此，我尝试更新列出的所有软件包apt list --upgradable。这也没有用。
目前，如果我尝试使用 apt 进行任何操作，例如，sudo dpkg --configure -a我会得到一长串输出，最后以

本系统20.04.4 LTS (GNU/Linux 5.4.0-1050-raspi armv7l)基于 Raspberry Pi 2。以下这我已经扩大了交换空间。
我还尝试清理boot分区，以便有空间进行更新。现在我有 140+ Mb 的可用空间/dev/mmcblk0p1 253M 114M 139M 46% /boot/firmware，而且空间充足/。
这些都无济于事。
我尝试遵循安全建议，但现在系统却半坏了。有没有什么办法可以修复这个问题并正确安装软件包？

最近，我在 ubuntu 上遇到了类似的错误。我尝试了很多方法，但得不到任何帮助。我通过进入 ubuntu 的高级启动选项检查了 Linux 的最新映像，发现 linux-image-5.4.0-105-generic 是罪魁祸首，而 grub 默认不会选择此条目。因此，我通过选择以前的映像 linux-image-5.4.0-104-generic 解决了该问题，它对我来说运行良好。不知道 Ubuntu 是否会在其版本中修复该问题。
