SSL module is not available
If you are trying to use pip and get an error
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping
So you don't have any libraries installed to work with ssl.
Try installing them and then reinstall
Python
with
configure make install
In Ubuntu , Debian and other .deb Linux distros you can use the following command
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
In CentOS , RedHat Rocky and other .rpm based distors use
sudo yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel zlib* libffi-devel readline-devel tk-devel
Then download Python with wget the following command will work for most Linux distros
wget https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz ; tar xvzf Python-3.9.1.tgz ; cd Python-3.9.1 ; ./configure ; sudo make install
If it works fine you can start using pip.
If it did not - try uninstalling old Python first, and install new one after.
