这发生在 20.04 LTS 上。
答案1
我无法通过添加来重现此问题官方 PPA到我全新的 Ubuntu MATE 20.04.3 LTS 系统。我做了以下操作：
sudo add-apt-repository ppa:openshot.developers/ppa
sudo apt-get update
sudo apt-get install openshot-qt
因此，您必须检查 Qt 安装。我建议使用非标准版本重新安装 Qt 网络库_ZN15QIPAddressUtils8toStringER7QStringPh符号。使用以下命令：
sudo apt-get install --reinstall libqt5network5
并重试启动 Openshot。
