有人能帮我弄清楚为什么这个无法安装吗？并告诉我该怎么做才能让它正常工作。
答案1
我来到这里是因为 OpenBoard 网站建议我下载 Ubuntu 16 版本，但我使用的是 Ubuntu 18，因此运行时
sudo gdebi openboard_ubuntu_16.04_1.5.4_amd64.deb
我收到消息：
Dependency is not satisfiable: libavformat-ffmpeg56
你可以通过以下方法查看是否属于这种情况：
cat /etc/os-release
就我而言，我使用的是 Ubuntu 18。
然后，您可以在OpenBoard 发布页面。
我下载.deb了适用于 Ubuntu 18 的版本 1.5.3并成功安装：
sudo gdebi openboard_ubuntu_18.04_1.5.3_amd64.deb
奇怪的是，当我打开应用程序时，它告诉我有新版本可用，并将我发送到官方下载页面，在那里它重新建议我下载 Ubuntu 16 版本。忽略它就行了。
