Although smart is capable of handling https connections, this error is caused by the SSL_CERTIFICATE issue that is affecting yocto build system. For more information, you can refer to this [https://lists.yoctoproject.org/pipermail/yocto/2015-July/025774.html discussion]. <br>
At the moment we are still working on this issue in the attempt to find a permanent solution. Unfortunately, the SSL_CERTIFICATE problem also affects other tools for which a temporary workaround is provided, see [http://wiki.dave.eu/index.php?title=Yocto_build_system_FAQs&action=edit#Q:_Why_does_pip_return_There_was_a_problem_confirming_the_ssl_certificate:_.5BSSL:_CERTIFICATE_VERIFY_FAILED.5D_certificate_verify_failed_.28_ssl.c:590.29_-_skipping_.3F] [http://wiki.dave.eu/index.php?title=Yocto_build_system_FAQs&action=edit#Q:_How_can_I_turn_off_git_SSL_verification.3F ].
===Q: <span id="Q2"></span> Why does pip return There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) - skipping ?===
In order to solve this problem, a possible workaround consist of disabling the SSL CERTIFICATE checking as suggested in the following example:<br>
''pip install pyserial --trusted-host pypi.python.org --index-url=<nowiki>http://pypi.python.org/simple/</nowiki>'' <br>

===Q: <span id="Q3"></span> How can I turn off git SSL verification? ===
Since the SSL_CERTIFICATE problem affects also 'git', it is suggested to turn off the SSL CERTIFICATE checking in the case you are trying to work with a repository over https. In order to achieve this, from the local folder export the GIT_SSL_NO_VERIFY variable, in this way:
''export GIT_SSL_NO_VERIFY=1''
