Archive repository

Recently, my phone got broken and began reusing a previous android 6 and then I found several problems with f-droid.

Some apps are listed as not compatible with my android v6. However, I know that they were compatible before as I 've been using for ages (note that I’ve no security concerns as they are offline apps)

From “Settings, Repositories” i can’t see how to enable “archive” so, I try to add manually but QR and URL failed, even i tried to add izzy’s repo with no better luck.

From f-droid webpage i can’t find the old versions of apps.
Then I decide to install “F-droid Classic” and it has the old options to enable repositories, including “Archive” BUT it produces the “Error getting index file” error.

Fortunately from Izzy i was able to find the old apks from archive, and curiously the apk urls points to f-droid servers.

Most users would not continue after the 1st step, some will throw away the phone but other will not be f-droid users anymore.

Regarding the current lack of support for “archive”
is it caused by limits of hardware/bandwidth?
Just a issue/bug?
