Confusing "App not installed" toast if APK not found

Fdroid did not have the download file link on hand due to nonupdated repos. Pressed install. It could not obtain file so it showed "app not installed" (as if it executed an installation file and file was rejected) instead of "not found" or (apparently) "timed out" since it took time to give error, and didn't even know it could not obtain it.

Version 1.15.6 Lenovo TB-x505F android 10. - you should make fdroid compile such a string to paste.
