当ubuntu 10.04上有可用空间时，为什么dpkg配置会耗尽空间？

有7Gb可用，但

~ # dpkg --configure -a

问题是您的/boot分区已满100%。新的linux内核将安装在那里，但如果分区已满，它们显然无法安装

检查是否已安装旧内核并将其卸载

dpkg -l | grep linux-image

将告诉您安装了哪些linux内核

uname -a

---

将告诉您当前使用的内核。

因为/boot上没有空间了

只是一个暗中操作，但可能是因为您正在尝试更新内核映像。如果您注意到，您的启动分区中还有大约400k，它可能正试图复制到那里。非常有用。
