Despite gnirehtet running as the only internet access on a smartphone, F-Droid : “No internet” above, although I can install apps, but the issue:
Updates, if I swap the display: “Cannot update, are you connected to the internet?”.
If I enable e.g. mobile data, I can get the update list, disable mobile data then as installing apps I can update.
Same issue as Google Play Inconsistent behavior with Play Store updates · Issue #37 · Genymobile/gnirehtet · GitHub .
