@rajudev either rename the zip to .apk or get it from here: https://apt.izzysoft.de/fdroid/index/apk/com.h.pixeldroid
Something is wrong in Firefox and/or the gitlab instance we use, it renames the apk to zip when downloading for some reason...
Renamed, it worked.
Thanks a ton for your work.
*Me goes back to setup and use the app now*
