Unfortunately the F-Droid client on that device can’t install it.. it says downloading but doesn’t download anything and says not installed.
It suggests version 1.38 of the App so I thought I would use my main device to get that and copy over.
Unfortunately .. I am too stupid to add the F-Droid archive repo to the list of repositories. I know it used to be totally easy.. and now I have tried scanning the qr code, tried to enter the URL, nothing works?
The F-Droid client on the old Android is 1.15.2 and is displaying 3 versions that were installable but downloading failed for some reason.
Most likely certificate error but didn’t see any error message when trying to download the package on the old device. Previously it likely attempted to update the repos in the background but if it displayed an error message I have missed it.
After trying to update the repos manually it shows me as suspected many certificate errors.
The summary..
on an old device with a long ago installed F-Droid client the certificate error messages are very easy to miss
on a new device with the latest F-Droid client enabling the archive repo is slightly confusing and actually displaying the archived versions required switching repos in the package view of the client which was unexpected - I thought/remembered there would simply be a much longer list of package versions if the archive repo is enabled
IMHO it would be more intuitive if below the list of the packages from the active repo there would be a button or fold element to display the list of archived versions or the two lists very just separated by some line with a hint like “archived versions below”
Got the package.. next will try to install the necessary certificates.
