Does installing Zoom, MS Teams and Webex fit into any of these methods? I guess my question is about all the .deb and .rpm packages out there, that cannot be installed permanently in an App Qube.
Usually, I download the installation .deb or .rpm package, move it to the Template, and run sudo apt install .package or sudo dpkg -i install .package or for Fedora sudo dnf install .package in the template.
This would of course require manual update of the package (download new version, move to template, and re-install).
Is there a better way to do this?
