update-initramfs：错误 24：写入错误：无法写入压缩块

Question

我几个月来一直在运行自定义内核，没有模块，没有 initramfs，没有 initrd。

\n

我已经安装了一个新的网络摄像头（锁定...），当然它不起作用，因为我没有正确的模块。我从 5.7.9 开始构建新内核。

\n

(...)copying an oldconfig from the original kernel from the distribution (linux mint) into the source rep(...)\nmake oldconfig\nmake\nmake modules_install\n

\n

但最后一步失败了

\n

我在启动时见过很多空间问题，但似乎不是我的情况。

欲了解信息：

和磁盘使用情况...

我也修改了一些Grub2参数，我不知道这是否会导致问题......

\n

实际上，我可以在任何内核上启动（原始内核、使用 initramfs 启动、我的自定义内核...），但我就是无法安装这个新内核。\n有什么想法吗？

回复中的重要反馈sudo apt upgrade是：

Error 24 : Write error : cannot write compressed block

换句话说，可能没有足够的空间来/boot写出并完成升级。要检查，请键入：

df -h | grep boot

如果您已经使用了大约 90% 的空间并且只有几十兆字节的可用空间，这显然是您的问题。但是，这取决于您的自定义内核所需的空间。

修复方法是删除不需要的内核映像。输入sudo apt list --installed | grep linux-image，你会得到类似这样的信息：

linux-image-5.4.0-54-generic/focal-updates,now 5.4.0-54.60 amd64 [installed,auto-removable]
linux-image-5.4.0-56-generic/now 5.4.0-56.62 amd64 [installed,local]
linux-image-5.4.0-58-generic/focal-updates,focal-security,now 5.4.0-58.64 amd64 [installed,automatic]
linux-image-5.4.0-59-generic/focal-updates,now 5.4.0-59.65 amd64 [installed,automatic]
linux-image-generic/focal-updates,now 5.4.0.59.62 amd64 [installed,automatic]

使用以下方法删除不需要的图像：

sudo apt remove linux-headers-5.4.0-54 linux-headers-5.4.0-54-generic linux-image-5.4.0-54-generic linux-modules-5.4.0-54-generic

替换5.4.0-54您的内核映像。您无需重新运行sudo apt upgrade -y. 但是，如果你这样做，你会看到类似这样的东西：

Use 'sudo apt autoremove' to remove them.

因此，执行sudo apt autoremove并在将来阅读输出，apt upgrade并确保做好你的家务工作！
