Sadly, since January 1st, 2020 Termux team dropped[0] support for
Android 5.x/6.x, so actually in
F-Droidrepo it now requires minimum
Android 7.x:
> Support for Android 5.x.x - 6.x.x is dropped forever. Time to upgrade your devices or learn how to backport git changes.[1]
And this part from Termux devs reply is especially cynical:
> ... Time to upgrade your devices...[1]
It looks like they has a contract with devices manufacturers...
... No, I no need such type of "app improvements in new version" which require me to buy a new device.
FTR, In F-Droid Archive[2] repo there is still Termux v0.75 for Android 5.x/6.x (which I'm using on Ido device), but it is horrible because Termux packages repo for Android 5.x/6.x are now disabled[3] too.
