I just installed GrapheneOS in my Pixel, but I couldn't fine Signal on F-Droid. Wäre should I go and geht it?I mean, its's FOSS, so I thought they'd provide an APK vor something somewhere...
Signal is packaged by many people now, you can add a third party repo and you're good to go.. If you're on GOS you can use Signal FOSS which is the debloated version of Signal
If there is on fdroid it is not authentic, make sure to see if it comes from a trusted source as signal does not put it on f-droid themselves, possibly leaving the door open to scams!
You do you. I don't use Signal so I'm not sure if using GitHub would mean you need to revisit the page and download a new APK whenever you want to update. Aurora could simplify that a bit.
