to install scipy for installing scikit learn and got an error like this

Reading package lists... Done

Package libatlas-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libatlas-base-dev:i386 libatlas-base-dev

E: Package 'libatlas-dev' has no installation candidate

I have tried updating but nothing seems to work.

You may have been misdirected by Google into following instructions on a page such as https://scikit-learn.org/0.16/install.html . If the goal is to install scikit-learn you may be better off with just pip3 install -U scikit-learn according to https://scikit-learn.org/stable/install.html . That's what I did on Ubuntu 20.04.1 LTS.
