Pip install fails with “connection error" ssl problem

Question

I am kind of new to Python and I started learning about packages and I tried to install some packages and update pip but I always get this error:

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)'))': /simple/pip/

I tried to look online for a solution but anything I have tried by now has failed

Edit: solved it!

I have solved the problem and it was associated with my antivirus blocking pip. I have solved it by deleting my antivirus and everything works. Keep in mind that when I disable my antivirus and firewall, it didn't work and only worked when I deleted the antivirus completely.

I hope that if you have the same problem that will help you

What did you enter into the command line?

Please try updating your pip using the trusted option:

pip install --upgrade pip --trusted-host pypi.org --trusted-host files.pythonhosted.org

To make this setting permanent you can create a pip.ini file in your user folder that contains:

[global]
trusted-host = files.pythonhosted.org

Please note that this is a more generic solution, pointing to trust the fils.pythonhosted.org host.
It is important to investigate and understand the root cause of the issue (wrong time / date, for example, can be one of the possible ones).

thank you , this is working but i am looking for a premenet solution. can i apply this to trust this source by default?

So even after the pip update you still have the issue? Can you please share your Python / Pip / Windows version? And, also important, are you into a corporate network?

shaked maman Over a year ago

so my pip version is 20.1.1 and i got python 3.8 and i got windows 10 pro v1903 (64 bit) , and i dont use tools like fidder

shaked maman Over a year ago

In my case it was a clock misconfigured.

I fixed that following this tutorial: Network - NTP

Check if your system clock is correct:

timedatectl status

Local time: Fr 2018-02-23 08:47:13 UTC
                   Universal time: Fr 2018-02-23 08:47:13 UTC
                         RTC time: Fr 2018-02-23 08:47:13
                        Time zone: Etc/UTC (UTC, +0000)
        System clock synchronized: yes
 systemd-timesyncd.service active: yes
                  RTC in local TZ: no

If not, install chrony:

sudo apt install chrony

And start chronyd - the actual daemon to sync and serve via the NTP protocol

sudo chronyd
