Wow, what a thread
In the past I had these issues to install Signal. My solution (as low skill terminal user) was a standalone AppVM which I personally donāt like - one template for one app.
To avoid standalone AppVM I prefer standard AppVM with AppImages (if they are available). For this approach I would like to have a more integrated and user friendly approach in Qubes OS.
- Download AppImage (in any AppVM)
- Right-click on *.appimage than create AppImage AppVM (based on a minimal / āmediumā template with network on) and create a new folder āAppImageā in home directory. Somehow the same routine like ācopy to other AppVMā and āopen in disposable AppVMā. Afterwards copy *.appimage into this new folder.
- Add this AppImageVM to the AppImage menu (see proposal above).
Advantage:
Simple: Two-clicks software installation. (Beside the permission to launch the appimage) no terminal command required. Easy to maintain / update.
secure: App is isolated in its own AppImageVM. Possible to set individual firewall settings.
