我尝试使用 Google 和 StackOverflow 搜索 Fsearch 应用程序的安装错误。我的理论是，错误源于桌面文件符号链接的默认位置发生变化。github 上的版本的构建说明：https://github.com/cboxdoerfer/fsearch/wiki/Build-instructions
sudo apt install git build-essential meson itstool libtool pkg-config intltool libicu-dev libpcre2-dev libglib2.0-dev libgtk-3-dev libxml2-utils
git clone https://github.com/cboxdoerfer/fsearch.git
cd fsearch
meson builddir
ninja -C builddir install

没有这个名字的目录。但是有一个目录，里面有桌面上显示的所有内容：以及更多内容：
# Second attempt...
sudo add-apt-repository ppa:christian-boxdoerfer/fsearch-stable
sudo apt install fsearch
获取带有放大镜图标的应用程序，但尝试运行它时会出现此对话框
david@davids:~/fsearch$ ls /usr/share/applications

所以我的问题是，我应该在 Fsearch 包的源代码或配置文件中查找哪里以将假定目标更改为 Ubuntu 18.04 的目标？
