Summary

The package apache-libcloud==2.0.0 here now initializes CA_CERTS_PATH as a NoneType as opposed to previous versions (namely apache-libcloud==1.5.0 here) which initializes this as a list with pre-configured values.

The commit message here justifies that change by indicating that the system CAs should be pulled in from certifi provided by requests but I was unable to import certifi (standalone or from requests) without first pip installing certifi. Perhaps certifi needs to be added as a dependency?

It should be noted that when I installed certifi manually, the format of CA_CERTS_PATH was a string so .insert() and .append() methods still failed. Seems like this line in apache-libcloud needed to be brought up one level of indentation but I'm not positive and could use a second set of eyes before pursuing a bug report there.

Workaround

In the interim, rolling back apache-libcloud==1.5.0 seems to do the trick.
