1、如何删除ubuntu旧内核？1.可以用这个命令解决sudo aptitude purge ilinux-image-.*(!uname -r)2.升级系统后，开机时就会出现很多版本，如2.6.32-24.2.6.32-31等。只要删除旧内核就可以了，但至少保留一个旧内核。修改grub.cfg的权限为可写，然后删除以下红色部分重复的内容。最后再把grub.cfg的权限为只读就行。# DO NOT EDIT THIS FILE# It is automatically generated by /usr/sbin/grub-mkconfig using templates# from /etc/g
