我正在运行 Ubuntu Server 16.04，升级到 linux-image-4.4.0-103-generic 失败，因为我的 /boot 几乎已满（200MB 中的 188MB）。

dpkg 显示我只安装了 2 个最新内核（4.4.0-96-generic 和 4.4.0-97-generic）。

我想过卸载其中一个以便为新内核腾出空间，但是 uname -r 显示 4.4.0.96-generic 作为当前内核，而不是 4.4.0-97-generic。我不确定为什么没有使用更新的内核，如果不需要，我也不想卸载其中任何一个。
claude@shannon:~$ uname -r
4.4.0-96-generic
sudo apt-get autoremove 失败，因为 /boot 太满
gzip: stdout: No space left on device
(and so on)
如何安装最新内核并删除旧内核软件包？
答案1
您可以尝试手动mount /dev/sdx /boot（其中 x 是启动分区，假设使用SATA）并 rm 不需要的映像。
请记住，引导加载程序配置也必须更新。 （例如假设使用 grubgrub-mkconfig /boot/grub/grub.cfg或手动编辑它）
答案2
好的，我能够修复它。事实证明，在之前更新到 4.4.0-97-generic 后服务器没有重新启动，因此它仍在运行 4.4.0-96-generic。我关闭了所有服务并重新启动，它使 4.4.0.97-generic 成为内核。然后，我跑了
sudo apt-get autoremove
sudo apt-get update
sudo apt-get dist-upgrade
并再次重新启动。现在4.4.0-103-generic是内核，4.4.0-97-generic是旧内核。
