我已经在我的电脑上安装了 Ubuntu 18.04.1 和 Windows 10华硕 gl503ge笔记本电脑。
以下是 grub 检测到的内容:
artur@arturGL503GE:~$ sudo update-grub
[sudo] password for artur:
Sourcing file `/etc/default/grub'

如你所见,由于某种原因,有两个 Linux 映像vmlinuz-4.15.0-**45**-generic
和vmlinuz-4.15.0-**44**-generic
输出如下lsblk
:
artur@arturGL503GE:~$ lsblk

答案1
这是正常的。Ubuntu 安装会保留两个内核:当前内核和上一个内核。这是针对因某种原因无法启动最新内核的情况。
如果您删除相应的linux-generic-...
包,它vmlinuz
也将被删除。
我不建议这么做。
答案2
如果您确实要删除备份,那么:
sudo apt purge vmlinuz-4.15.0-45-generic
并且如果有任何文件它拒绝删除文件:
sudo rm -r '/path/to/file'
但这可能会毁了您的系统。
