【Linux日記】linux-generic 安裝出現問題　導致 linux-image-generic 等安裝失敗

網上查了一下，據說是內核升級的時候/boot分區空間不足造成的

Linux升級後，內核版本太多，導致空間不足，所以需要卸載版本比較老的內核

卸載方法
１．首先查看自己安裝的內核
使用命令：dpkg –get-selections | grep linux-image

linux-image-4.4.0-21-generic            install
linux-image-4.4.0-34-generic            install
linux-image-4.4.0-36-generic            install
linux-image-4.4.0-38-generic            install
linux-image-extra-4.4.0-21-generic      install
linux-image-extra-4.4.0-34-generic      install
linux-image-extra-4.4.0-36-generic      install
linux-image-extra-4.4.0-38-generic      install
linux-image-generic             install

２．查看正在使用的內核
使用命令：uname -a

Linux xh-K55DR 4.4.0-38-generic #57-Ubuntu SMP Tue Sep 6 15:42:33 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

3.刪除舊的內核
注：考慮到linux新內核的不穩定性，所以建議留1-2個內核
使用命令：sudo apt-get purge linux-image-4.4.0-21-generic

使用'sudo apt autoremove'來卸載它(它們)。
