在 Ubuntu 15.04 上安装 xbacklight

我正在尝试使用安装 xbacklight

sudo apt-get install -y xbacklight

但是出现与 mysql 相关的错误。运行上述命令后，会弹出一个新窗口来设置 mysql 的密码。但设置后，终端中显示以下错误。

我已经在 14.04 Ubuntu 中安装了 xbacklight。我应该如何在 15.04 中安装它？

运行以下命令：

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

然后，我强烈建议你在做其他事情之前先更新你的软件。运行以下命令之一：

sudo apt-get upgrade

或者，建议：

sudo apt-get dist-upgrade
