我正在尝试安装桌面调光器 v4.0.4 (amd64)在我的 Ubuntu 20.04 上使用 DEB 包。该应用程序显示在“应用程序”菜单中，但未打开。尝试将其作为命令行实用程序运行时，出现以下错误：
user@thehost:~$ desktop-dimmer
Gtk-Message: 18:23:15.355: Failed to load module "canberra-gtk-module"
(desktop-dimmer:2454): Pango-ERROR **: 18:23:15.610: Harfbuzz version too old (1.2.7)
Trace/breakpoint trap (core dumped)
如何在 Ubuntu 上更新 Harfbuzz？

问题不是您系统的 Harfbuzz 版本太旧，而是软件包中提供的 Desktop Dimmer 二进制文件嵌入了太旧的 Harfbuzz 版本。
我不确定如何引入依赖关系，但希望从源代码重建将使用更新的版本。
