Curl Certificate Error when Using RVM to install Ruby 1.9.2

Question

RVM is running into a certificate error when trying to download Ruby 1.9.2. It looks like curl is having a certificate issue but I am not sure how to bypass it

Answer 1

On Centos 5.6 (Final) I had a problem with installing rvm 1.9.2 The error was:

curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). The default
 bundle is named curl-ca-bundle.crt; you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
ERROR: There was an error, please check /usr/local/rvm/log/ruby-1.9.2-p290/*.log. Next we'll try to fetch via http.
Trying http:// URL instead.

Halting the installation.

Here is a list of actions which helped me to solve the problem

$ curl-config --ca # show path to the certificate
/usr/local/share/curl/curl-ca-bundle.crt
$ cd /usr/local/share/curl/ # go to that path
$ cp curl-ca-bundle.crt curl-ca-bundle.crt.bak # backup certificate
$ curl http://curl.haxx.se/ca/cacert.pem -o curl-ca-bundle.crt # download new
$ rvm install 1.9.2 # bingo it works

Btw curl version is curl 7.18.0 (to check '$ curl -V')
