问题描述

升级 ubuntu 14.04.1 后，提示/boot 分区空间不足。

环境

操作系统: Ubuntu 14.04.1

磁盘空间

df -Th

Filesystem                  Type      Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-root ext4      114G   36G   72G  33% /

/dev/sda1                   ext2      236M  185M   39M  83% /boot

注意，boot 分区可用空间确实不足，因为之前升级过几次。

解决方法

删除掉旧的文件，释放一些空间(新装系统划分/boot分区分配的大一些)。

当前内核版本

uname -r
3.13.0-43-generic

已安装的内核

dpkg --get-selections |grep linux-image
linux-image-3.13.0-24-generic            install
linux-image-3.13.0-35-generic            install
linux-image-3.13.0-36-generic            install
linux-image-3.13.0-37-generic            install
linux-image-3.13.0-40-generic            install
linux-image-3.13.0-43-generic            install
linux-image-extra-3.13.0-24-generic        install
linux-image-extra-3.13.0-35-generic        install
linux-image-extra-3.13.0-36-generic        install
linux-image-extra-3.13.0-37-generic        install
linux-image-extra-3.13.0-40-generic        install
linux-image-extra-3.13.0-43-generic        install
linux-image-generic                install
