Albert 在Linux系统下是一个类似类似Windows的Everything和Listary软件，除了找文件和应用还可以进行计算器计算，打开网页等操作。

Ubuntu 18.04 LTS 安装Albert

根据 https://software.opensuse.org/download.html?project=home:manuelschneid3r&package=albert，有两种方法进行安装，我采用的第二种方法。

方法1：Add repository and install manually

echo 'deb http://download.opensuse.org/repositories/home:/manuelschneid3r/xUbuntu_18.04/ /' | sudo tee /etc/apt/sources.list.d/home:manuelschneid3r.list
sudo wget -nv https://download.opensuse.org/repositories/home:manuelschneid3r/xUbuntu_18.04/Release.key -O "/etc/apt/trusted.gpg.d/home:manuelschneid3r.asc"
sudo apt update
sudo apt install albert

方法2：Grab binary packages directly

下载 albert_0.16.1_amd64.deb 安装包，下载链接：https://download.opensuse.org/repositories/home:/manuelschneid3r/xUbuntu_18.04/amd64/albert_0.16.1_amd64.deb

sudo dpkg -i albert_0.16.1_amd64.deb

遇到问题，缺少依赖

提示是缺少 libmuparser2v5, libqt5charts5, libqt5concurrent5 和 libqt5x11extras5.

解决办法

sudo apt --fix-broken install
sudo dpkg -i albert_0.16.1_amd64.deb

安装成功

设置热键

功能失效（其实没有失效），重装

发现功能没有生效，准备重装，先卸载：

sudo dpkg --purge albert 

然后我用方法1进行了重装，还是没有功能生效，查询后才发现需要在extension里面开启对应的功能，比如需要查找Applications就需要把它勾选。
