@arunkumarchan

add-apt-repository ppa:deadsnakes/ppa

Env variable in not set in this ..
how can i set it ?

Now is December 2020, your code doesn't work.

Somehow, those codes just got us Python 3.5.2, not Python 3.6.

so how can we get python 3.6

I have to build Images FROM ubuntu:18.04.

This way works.

In case you must use 16.04 only, I have no idea.

wait what do u mean by this way . i was using centos 7 and everything worked but now i converted to ubuntu and idc about the version i just need jdk8 , python3.6 and pip . could u help me out . i am relaly new to all this and any help would be extremly appreciatedd

Does some add-apt-repository ppa:??? latest updated?
