我对Linux Mint和Remmina软件有问题。在更新系统之前，它一直在工作。当我想在Windows中的PC上启动RDP时，在日志下面：
root@kevin-Aspire-ES1-311:~# flatpak run org.remmina.Remmina
Remmina plugin glibsecret (type=Secret) has registered but not yet initialized/activated. Initialization order is 2000.

StatusNotifier/Appindicator support: not supported by desktop. libappindicator will try to fallback to GtkStatusIcon/xembed
Warning: Remmina is running without a secret plugin. Passwords will be saved in a less secure way.

感谢您的帮助！ ：）
我有一个类似的问题，并设法通过以下方法解决：
flatpak install org.freedesktop.Platform.openh264
