Cancelling update results in infinite process exit/spawning

What Operating System

Linux (Debian)

Debug Code

FTB-DBGMAPUWUTOLO

Describe the bug

#1126 seems to still be an issue or it has broken again since being fixed.
The app wanted an update today but I cancelled the authentication prompt and I saw the app was continuously exiting and opening in the background.

On a related note, maybe the app shouldn't be immediately prompting for a password with no indication as to why it needs it. Instead, I think the app should open and simply say that an update is required and then show a button that will trigger the update process/authentication.

Steps to reproduce

1. Try opening the FTB app when an update is required
2. Cancel the password prompt
3. See the ftb-app process(es) continuously being killed and relaunched in the background

Expected behaviour

The app exits cleanly, shows an error that an update is required after you cancel the password prompt, and/or the app opens properly with a blocking message saying an update is required and gives a button to start that process without just asking for a password on launch.
