I apologize in advance because I’m almost sure I’ve seen this covered in another thread before, but I can’t find it any more:
Starting with 4.2., F-Droid started to act up when updating installed apps. Some can be updated without any problem. Others (like Ankidroid and F-Droid itself) show up in the update-panel and seem to download correctly. When I try to actually update them, though, there’s just a generic error on the top of the screen and that’s it.
I have not so far tried to uninstall the affected apps, neither have I tried to uninstall and re-install F-Droid (which, well, is an affected app). That’s mainly because I don’t know how this uninstall/reinstall would affect the app data on the device, but also because (as I said earlier) I thought I had seen this problem here before and I’d rather do “the right thing” solving it than start experimenting on my own.
Any ideas? Like, for a start, can I see anywhere why exactly an update fo within F-Droid failed?
