@Captain_Baka error in META-INF... ?
@yesfreenet @Captain_Baka What happens if you install the certificate and then right the F-Droid Client package? Do you have any screenshots of the error?
I had already installed F-Droid and also set it up to only use Archive but it didn't load the app list. Don't know why, it just said that it couldn't load any packages.
F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.
