[Slackbuilds-users] A certificate error is made when fetching vidalia.

[crocket]

ERROR: cannot verify archive.torproject.org’s certificate, issued by
“/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3”:
  Unable to locally verify the issuer’s authority.
To connect to archive.torproject.org insecurely, use ‘--no-check-certificate’.

It seems that DigiCert High Assurance CA-3 is present in ca-certificates package 
from slackware64-current.
How can I remove this error?
