[Linphone-users] cannot install flatpak on Debian 10

[Anil Felipe Duggirala]

hello,
I am trying to install the flatpak with the given command, however I am
getting the following error message:
error: The application
com.belledonnecommunications.linphone/x86_64/4.1.1 requires the runtime
org.freedesktop.Platform/x86_64/1.6 which was not found

My flatpak remotes list:
flathub         system
linphone-origin user,no-enumerate

Does the linphone installation automatically add a flatpak remote?

Please help,
thank you,
