Following from this, I am trying to install like so (in docker, but also same error directly on host):
RUN apt-get update && \
apt-get install -y software-properties-common && \
add-apt-repository -y ppa:deadsnakes/ppa && \
apt-get update && \
apt install -y python3.7
I am getting
E: Unable to locate package python3.7
E: Couldn't find any package by glob 'python3.7'
E: Couldn't find any package by regex 'python3.7'
This was working, and one day it stopped. I don't know if I did something, or if something happened on deadsnakes or elsewhere.
How to get Python3.7 in the docker, and in the host?
