无法删除旧内核
use*_*692 5 server uninstall kernel disk-usage
我正在尝试删除旧的内核版本，以便我可以升级。我使用的方法如下。
sudo apt-get purge linux-image-x.y.z-server
每次我运行它时，我都会收到以下错误：
<(Reading database ... 516009 files and directories currently installed.)

好的，所以我得到的是这告诉我我的空间不足，我知道。我还会不时收到一条关于运行以下命令以解决我的错误的消息，此时我再次收到 now space 消息。
sudo apt-get install -f
我尝试的一切都给了我现在的空间错误。令人沮丧..... 感谢您的帮助。
这是请求的输出，抱歉

为了防止将来出现“boot/no space”错误，请安装 ubuntu-tweak并使用它的 janitor 来频繁清理缓存的程序、旧内核、不需要的程序等。
安装后，转到“janitor”并选中左侧边栏中的“系统”复选框，然后按底部的“清理”。检查下图。
该命令来源：
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | grep -E "(image|headers)" | xargs sudo apt-get -y purge
我运行后仅释放了 723 MB 的磁盘空间。这将检查您正在使用的当前内核版本并删除其余版本。
