Failed to install AWS-SAM-CLI on Ubuntu 18.04.4

Description

I am failing to install AWS-SAM-CLI on my brand new Ubuntu 18.04-Laptop. I get an error when I call “sam --version”

Steps to reproduce

I followed https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install-linux.html I installed Python3.7 from source because libpython3.7m.so.1.0 was needed and was not installed by the package manager.

Observed result

The error is:

joern@joern-acer:~$ sam --version
Traceback (most recent call last):
  File "/home/linuxbrew/.linuxbrew/bin/sam", line 6, in <module>
    from pkg_resources import load_entry_point

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'aws-sam-cli==0.43.0' distribution was not found and is required by the application

Expected result

Here is a result from my old laptop with aws-sam-cli

joernkleinbub@joerns:~$ sam --version
SAM CLI, version 0.31.0

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Ubuntu 18.04.4
2. sam --version: should be 0.43.0

@kmeelu We had an issue with our 0.53.0 bottles that were not installing correctly after Homebrew updated python from 3.7 to 3.8. We were addressing that earlier today. Everything should be fixed now. If you are still running into problem, please cut a new issue.

Hi @awood45 , is there a release ongoing? Our CircleCI pipeline (which uses aws-serverless/install), is failing on that step:

See: https://docs.brew.sh/Homebrew-and-Python

Looking at the releases, it seems like there was a pre-release candidate but no update since. Is that correct?
