Certificate Errors

[karadikid]

ISSUE:
No matter what method I use to update CAs, my Ethambian from your repository fails to validate remote servers and cannot curl without -k. With research it appears that it may have a self-signed certificate in the CA hierarchy.

REPRO:

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
