[deleted] You could consider reinstalling Aurora Store from the F-Droid repo through an app store such as the F-Droid app, Droid-ify or Neo Store. You can keep it updated from there.
Or if you don't want to do that, you could consider using Obtainium and adding Aurora Store in it with the link to Aurora Store's Gitlab page. The apk signature from Gitlab is probably identical to the one from their website so it should work to keep it updated.
If you already use an F-Droid app store on your device, the simplest approach is probably to reinstall Aurora Store from there. If not, you can try out Obtainium.
