Well, you are trying to install new packages that require that also the underlying core packages are matching. Your ancient firmware from June contains much older packages.
Like lleachii already said, upgrade your firmware (=flash a new firmware) and then install matching new packages.
If you want to update only rarely, your should likely use the 19.07 stable branch. Note that the final 19.07.0 was tagger a few hours ago and will be release in a few days.
