/dev/sda1 /boot 已满

tag-icon • tag-icon boot ram nginx
/dev/sda1 /boot 已满

我知道有很多这样的问题，但我已经尽力去了解该怎么做，但却失败了。

我df -h知道我的/dev/sda1 /boot利用率是100%。

我完全不明白我应该删除什么。我正在运行 nginx 并想安装 nodejs，但在尝试时我被警告未满足依赖项，sudo apt-get install nodejs并sudo apt-get -f install因空间不足而失败。我可以就这一点获得一些具体指导吗？我感觉完全迷茫了。

sudo apt-get purge linux-image-x.x.x.x-generic

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
 linux-image-generic-lts-raring : Depends: linux-image-3.8.0-44-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

答案1

/boot包含（除其他内容外）您已安装的 Linux 内核。这些内核会不时更新。

打开终端并输入 dpkg --list | grep linux-image，然后点击ENTER

然后将其输出与 uname -r
...进行比较，其中输出告诉您正在使用上述哪个内容。

所有其他文件都可以删除，释放空间 - 除非您有理由保留它们。这可以通过替换此处的“linux-image-xxxx-generic”来实现：

sudo apt-get purge linux-image-xxxx-generic

对于每一个您想要删除的。

然后，在最后一次之后，你必须这样做来清理/重新创建启动菜单

sudo update-initramfs -u # 重新制作启动 ramdisk
sudo update-grub2 #重新创建启动菜单

这...

查找/ boot -type f -printf“％-16s％p \ n”| sort -nr | head -n 20

... 将显示 /boot 中最大的 20 个文件
