Activation - SSL Certificate error during Licensing

I get a 'a SSL Certificate Error prevented the license server from being reached' Message during Licensing

Some Linux distribution ship with Out of Date SSL Certificates. To rectify this do one of the following

1) Disable SSL check for Python Calls

To do that set an environment variable:

either permanently or just when starting Mari.

2) Update your System SSL Certificates

Go to a https:// address in a browser.

Click on the 'lock' icon next to the address in the browser.

Most likely on some https:// addresses it will state 'Certificate invalid' instead of 'valid'

Click on the Certificate and you should have the option to save or 'copy to file'.

Save the certificate on linux to /etc/ssl/certs/
