我正在尝试为通过 Flatpak 安装的 QOwnNotes 应用程序启用调试（遵循本教程：调试 Flatpak 应用程序）。
我已经安装了应用程序本身并为其 Sdk 和本身调试了部分：
$ flatpak install flathub org.qownnotes.QOwnNotes
$ flatpak install flathub org.qownnotes.QOwnNotes.Debug
$ flatpak install flathub org.kde.Sdk.Debug//5.14
然后启动应用程序：
$ flatpak run --command=sh --devel org.qownnotes.QOwnNotes
并通过以下方式运行它gdb：
sh-5.0$ gdb /app/bin/QOwnNotes
