ubuntu换最新内核
-
去https://www.kernel.org查看最新稳定内核版本
-
打开https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.6/ (假设此时最新版是5.4.6)
Build for amd64 succeeded (see BUILD.LOG.amd64): linux-headers-5.4.6-050406_5.4.6-050406.201912211140_all.deb linux-headers-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb linux-headers-5.4.6-050406-lowlatency_5.4.6-050406.201912211140_amd64.deb linux-image-unsigned-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb linux-image-unsigned-5.4.6-050406-lowlatency_5.4.6-050406.201912211140_amd64.deb linux-modules-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb linux-modules-5.4.6-050406-lowlatency_5.4.6-050406.201912211140_amd64.deb

wget下载包名里没有lowlatency的deb包 , sudo dpkg -i ***.deb 依次安装 :
linux-headers-5.4.6-050406_5.4.6-050406.201912211140_all.deb linux-headers-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb linux-modules-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb linux-image-unsigned-5.4.6-050406-generic_5.4.6-050406.201912211140_amd64.deb
-
查看已安装内核
dpkg -l|grep linux-image | awk '{print $2}'
-
删除旧内核
apt purge -y
-
更新grub 然后重启
update-grub reboot
-
检查一下是否更换成功
uname -r
如果不是要最新的,也可以在源里更新
apt update
apt search linux-image |grep 4.15.0-30-generic
apt install linux-image-4.15.0-30-generic
然后卸载旧内核步骤同上
