  • I couldnt find anything that works for python 2.7,I am still stuck at the same error,I tried https://stackoverflow.com/questions/44290926/pip-cannot-confirm-ssl-certificate-ssl-module-is-not-available , I tried `yum install openssl-devel -y` but I couldnt find any sources to hack as mentioned in the second solution in the link I shared – user3508811 Jan 21 '19 at 04:17

Try installing manually:

wget -P ~/.local/lib https://bootstrap.pypa.io/pip/2.7/get-pip.py
python2.7 ~/.local/lib/get-pip.py --user 
#if using bash
printf "\nPATH=\$PATH:~/.local/bin/" >> ~/.bashrc
source ~/.bashrc

    This fails at step2 with error `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 Could not find a version that satisfies the requirement pip (from versions: ) No matching distribution found for pip` – user3508811 Jan 24 '19 at 04:04
  • how to get rid of this SSL error?this has been the blocker for me – user3508811 Jan 24 '19 at 04:08
  • Did you compile python yourself? Have you got OpenSSL? See fx https://stackoverflow.com/questions/44290926/pip-cannot-confirm-ssl-certificate-ssl-module-is-not-available/46087798#46087798 – ErikWi Jan 24 '19 at 05:12
  • No,I didn't compile python myself...I don't seem to able to find the python source under `/usr/local` ,how to I find the source? – user3508811 Jan 24 '19 at 18:33
  • I added a screen shot of how my `/usr/local` looks – user3508811 Jan 24 '19 at 18:47
  • Try installing OpenSSL: ‘yum install openssl’ – ErikWi Jan 24 '19 at 21:04
  • ‘yum install openssl’ throws the output `Loaded plugins: security Setting up Install Process Package openssl-1.0.1e-57.0.6.el6.x86_64 already installed and latest version Nothing to do` – user3508811 Jan 24 '19 at 23:31
  • Strange, did you install python 2.7 from epel, with yum? – ErikWi Jan 25 '19 at 05:34
  • It was already present on the machine am using, so am not sure how it was installed,anyway to recover from this situation? – user3508811 Jan 25 '19 at 22:44
  • Python 2 will soon be End of life, can you use python 3? yum install python3. If not, yum install python2.7 to make sure it’s all there? – ErikWi Jan 26 '19 at 05:48
  • yum list python* – ErikWi Jan 26 '19 at 05:57

    has been updated to: https://bootstrap.pypa.io/pip/2.7/get-pip.py. The url in your post will now only work with Python3 – raw-bin hood May 11 '21 at 01:40

In newer versions of Ubuntu such as 20.04, python-pip is no longer a package. Therefore, the old:

sudo apt install python-pip

Will fail.

Here's how to work around this issue:

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
python get-pip.py

pip has dropped a support to python 2.7. If you still want to use it for python 2.7, downgrading the pip will help you:

sudo easy_install pip==20.3.4

Just go into terminal and type in:

sudo apt-get install python-pip

I know that this at least works on a raspberry pi.
