Ubuntu22.04系统切换内核版本
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

可总结如下，所要切换的Ubuntu, with Linux 6.2.0-37-generic为"1 > 2"
0 Ubuntu
1 Ubuntu 高级选项
1>0 Ubuntu, with Linux 6.8.0-51-generic
1>1 Ubuntu, with Linux 6.8.0-51-generic (recovery mode)
1>2 Ubuntu, with Linux 6.2.0-37-generic
1>3 Ubuntu, with Linux 6.2.0-37-generic (recovery mode)
1>4 Ubuntu, with Linux 6.2.0-26-generic
1>5 Ubuntu, with Linux 6.2.0-26-generic (recovery moe)
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
