Failed to update Telegram Flatpak when it required a new version of the runtime
Yesterday I pressed the button to update Telegram and got the following error message:
"Unable to update "Telegram Desktop": Refspec 'flathub:runtime/org.freedesktop.Platform.VAAPI.Intel/-x86_64/20.08' not found"
I then went and tried the flatpak update
command. This asked me whether to install the required runtime; I said yes, and the app was successfully updated.
