I cannot upgrade my Fennec F-Droid through F-Droid (Parsing error) on my FP1 running Kitkat. Have they bumped the minmal-sdk?
In F-Droid you can hide apps that are not compatible. Does Fennec still show up when you do that?
PS: According to F-Droid 63.0 requires 4.1+
The official Mozilla page of the current beta version 64 states Android 4.1 as minimum. So it should run on the FP1.
I can see it too now. I missed that you can expand the version information:
Maybe the download is corrupt. I cleared the cache and am trying to install again.
Edit: Installation worked now.
