在Ubuntu 15.04上安装xbacklight

Question

我正在尝试使用

sudo apt-get install -y xbacklight

但是获得与mysql.After运行在上面的命令相关的错误--一个新窗口弹出，在设置mysql.But密码后，它会显示终端中的以下错误。

Reading package lists... Done

Setting up mysql-server-5.6 (5.6.30-0ubuntu0.15.10.1) ...
/usr/sbin/mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)
Fatal error in defaults handling. Program aborted
AppArmor parser error for /etc/apparmor.d/usr.sbin.mysqld in /etc/apparmor.d/usr.sbin.mysqld at line 9: Could not open 'abstractions/mysql'

我已经在14.04 Ubuntu.How中安装了xbacklight，我应该在15.04中安装吗？

Answer 1

运行以下命令：

sudo apt-get update
sudo mkdir /etc/mysql/conf.d
sudo apt-get -f install

然后，我认真地建议你在做其他事情之前更新你的软件。运行以下命令之一：

sudo apt-get upgrade

或，建议：

sudo apt-get dist-upgrade
