Recently and issue came up that prevented Bundler from being installed, and subsequently caused the Boxcar installation to fail. That error looks something like this:

Unable to download data from - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

The fix (overview)

OpenSSL ships with a utility called c_rehash which you can invoke on a directory to have all certificates indexed with appropriately named symlinks.

  1. Install openssl
  2. Install ca-certificates
  3. Run the c_rehash utility

The copy-and-paste fix

I recommend doing this with trolley, as it makes package management really easy. If you're not using it, or don't want to, just download and install these packages manually from your favorite mirror.

trolley install openssl # Not necessary if you have it installed
trolley install ca-certificates
