几个月来我一直在运行自定义内核，没有模块、没有 initramfs、没有 initrd。
我买了一个新的网络摄像头（锁定...），当然它不能工作，因为我没有正确的模块。我从 5.7.9 开始构建一个新内核。
(...)copying an oldconfig from the original kernel from the distribution (linux mint) into the source rep(...)
make oldconfig
make
make modules_install
但最后一步失败了
make install

我在启动时发现了很多空间问题但似乎不是我的情况。

我也修改了一些 Grub2 参数，不知道这是否会导致问题......
实际上，我可以启动我的任何内核（原始内核、使用 initramfs 启动、我的自定义内核……），但我无法安装这个新内核。有什么想法吗？

回复中重要的反馈sudo apt upgrade如下：
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
如果您已使用了约 90% 的空间，并且只剩下几十兆的可用空间，那么这显然是您的问题。但是，这取决于您的自定义内核所需的空间。
解决方法是删除不需要的内核映像。输入后sudo apt list --installed | grep linux-image您将得到如下内容：
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。您不需要重新运行sudo apt upgrade -y。但是，如果您这样做，您将看到类似以下内容：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following packages were automatically installed and are no longer required:
linux-headers-5.4.0-56 linux-headers-5.4.0-56-generic linux-image-5.4.0-56-generic linux-modules-5.4.0-56-generic
linux-modules-extra-5.4.0-56-generic
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
因此，执行sudo apt autoremove并在将来读取输出apt upgrade并确保做好您的家务！
