解决 vboxdrv.sh: failed: Cannot change group vboxusers for device /dev/vboxdrv.

virtualbox 报错 ,看提示让执行以下

sudo /sbin/vboxconfig

如果报错:

vboxdrv.sh: failed: Cannot change group vboxusers for device /dev/vboxdrv.

那么应该是本用户没有加入vboxusers.
参考:

执行:

sudo addgroup vboxusers 
sudo adduser your_username vboxusers 
sudo /etc/init.d/vboxdrv setup 

即可

错误原因应该是我卸载mysql时将一些旧的配置删了,我不知道,我相信没人会闲到犯和我一样的错误
