Ubuntu系统切换内核版本
- 1 更换镜像源
- 2 查询可更换的内核版本
- 3 安装合适版本内核
- 4 切换内核版本
- 5 验证内核是否更换成功
1 更换镜像源
使用鱼香ROS脚本来更换镜像源
wget http://fishros.com/install -O fishros && . fishros
2 查询可更换的内核版本
sudo apt update
sudo apt search linux-image
3 安装合适版本内核
此处选择linux-image-6.2.0-37-generic
# 内核镜像
sudo apt install linux-image-6.2.0-37-generic
# 内核头文件
sudo apt install linux-headers-6.2.0-37-generic
# 内核模块
sudo apt install linux-modules-6.2.0-37-generic
# 内核额外模块
sudo apt install linux-modules-extra-6.2.0-37-generic
查看是否安装成功
dpkg -l | grep linux-image
4 切换内核版本

更改grub默认启动项
sudo gedit /etc/default/grub
更新开启引导文件
sudo update-grub
重启
reboot
5 验证内核是否更换成功
uanme -r
