Anbox on Ubuntu MATE

Hi there, I downloaded Ubuntu mate. 17.10. Loaded to banana pi m1+. Everything is fine, but I am not able to install anbox. Tutorials did not help me. Is here real option to install anbox here?

Thanks!

17.10 is past end of life, I recommend you either upgrade or do a clean installation of 18.04.

A few days ago on Ubuntu 18.04 I installed Anbox following the instructions on Jithub


explained more clearly than those of the Anbox site (even if they are the same)
https://docs.anbox.io/userguide/install.html

then I dowloaded my apk file from https://apkpure.com/ and installed it
https://docs.anbox.io/userguide/install_apps.html

Out of curiosity, I installed Audible which works perfectly.
I tried to install 2 more apps but they don't work, I don't know why.
