Error: gpg: keyserver receive failed: No name during install

Thank you for providing this awesome work. I was trying to install this debian into my termux (Android 7), however there was an error:

~ $ chmod u+x debian_on_termux.sh 
~ $ ./debian_on_termux.sh

after examining the script, it seems these commands caused error (both due to deprecation and keyserver failed to receive key)

(...)
apt-key adv --recv-keys DCC9EFBF77E11517
(...)
apt-key adv --recv-keys 648ACFD622F3D138

replacing both of them seems fixed the issue

I will provide pull request soon

i could be wrong but i think you should be using "debian_on_termux_10.sh" for android 7
