Termux or userland (terminal) Android install

The problem is google’s ban of any …x (execute perm.) in any terminal software outside PLAY, for API 29+ i.e. Android 10.0+ .

I see hardly any mention on Android + Octave here, I’ve using octave 4 & 5 in A 6,8,9 till now I have to buy new device with android 10.
Anyone has experience with A10 + octave 5? with F-droid Termux? or Userland ? Even in A11 to have an alternative would be great! (probably too soon )

The dire alternative is to try find A9 device, but for how long will it be possible doing that…

Thankx
Jo
