ubuntu---禁止更新内核

系统内核 4.15.0-29  更新成了 4.15.0-88，降级内核并禁止更新内核

查看已安装内核：dpkg --get-selections |grep linux-image
 
查看正在使用的内核：uname -a
 
删除旧内核：
sudo apt-get remove linux-image-x.xx.x-xx-generic
sudo apt-get remove linux-image-extra-x.xx.x-xx-generic  
 
或用这个命令移除：
sudo dpkg --purge linux-image-x.x.x-xx-generic
 
禁止更新内核，需时间来验证
 
sudo apt-mark hold linux-image-x.xx.x-xx-generic
sudo apt-mark hold linux-image-extra-x.xx.x-xx-generic
 
如果需要恢复原来的设定的话即允许更新内核，执行如下命令即可：
sudo apt-mark unhold linux-image-x.xx.x-xx-generic
sudo apt-mark unhold linux-image-extra-x.xx.x-xx-generic
