On a completely new install of Ubuntu I'm getting the following errors when using wget:

wget https://test.sagepay.com

--2012-03-27 12:55:12--  https://test.sagepay.com/
Resolving test.sagepay.com... 195.170.169.8

Unable to locally verify the issuer's authority.
To connect to test.sagepay.com insecurely, use `--no-check-certificate'.

I've tried installing ca-certificates and configuring the ca-certs and they appear to all be setup in /etc/ssl/certs.

The same issue exists for cURL:

curl https://test.sagepay.com

curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Which leads me to believe it's something wrong with openssl server wide.

wget and curl both work correctly locally on OSX and I have confirmed with a few people that it's working on their servers so I suspect it's nothing to do with the server I'm attempting to connect to.

Any ideas or suggestions on things to try to narrow it down?

Thank you

  • It would be best to remove the solution from your question and post as an answer.

So it turns out that installing the ca-certificates package didn't install the one that I needed. I found this post about certificates being presented out of order. This seems to be the case with my request to sagepay.

The solution ended up being to install another CA certificate from Verisign. I'm not sure why this fixes the issue with it being out of order but it does, but I suspect the out of order issue really isn't a problem at all and it was infact because I was missing a certificate all along. The additional certificate is available in that post but I didn't want to blindly trust it. I've looked at the list of CA certificates from cURL's site and it is listed there so I do trust it.

The certificate:

Verisign Class 3 Public Primary Certification Authority
=======================================================

I put this in a file in:

/usr/share/ca-certificates/curl/Verisign_Class_3_Public_Primary_Certification_Authority-from_cURL.crt

I then modified the /etc/ca-certificates.conf and added the following line at the end:

curl/Verisign_Class_3_Public_Primary_Certification_Authority-from_cURL.crt

After that I ran the command:

sudo update-ca-certificates

Looking into the /etc/ssl/certs directory I see it correctly linked:

ls -al | grep cURL
lrwxrwxrwx 1 root root     69 2012-03-27 16:03 415660c1.0 -> Verisign_Class_3_Public_Primary_Certification_Authority-from_cURL.pem
lrwxrwxrwx 1 root root     69 2012-03-27 16:03 7651b327.0 -> Verisign_Class_3_Public_Primary_Certification_Authority-from_cURL.pem

And everything works!

curl  -I https://test.sagepay.com
HTTP/1.1 200 OK...

  • This didn't exactly work for me, but this did on Ubuntu 14.04: sudo ln -s /usr/share/ca-certificates/mozilla/Verisign_Class_3_Public_Primary_Certification_Authority.crt /etc/ssl/certs/415660c1.0

  • Ah, found it. Digging around, I found that after an update, all certs in /etc/ca-certificates.conf were deselected. I removed the leading "!" on each line, ran update-ca-certificates and wget worked again

Can you do a curl -Iv https://test.sagepay.com and update your question with those results?

What I see on a Ubuntu 10.04 box is:

$ curl -Iv https://test.sagepay.com
* About to connect() to test.sagepay.com port 443 (#0)
*   Trying 195.170.169.8... connected
* Connected to test.sagepay.com (195.170.169.8) port 443 (#0)

and so on, so that looks OK.

Note the CApath is /etc/ssl/certs. Can you run sudo update-ca-certificates ? That should be in the ca-certificates package. If that package is not installed, try sudo apt-get install ca-certificates. If the ca-certificates package is not installed, then Ubuntu's list of CA certificates is not installed, and you will get validation errors.

Edit:

I see I skipped over the part where you say you've installed the ca-certificates package. In that case, we really need to see the verbose output from curl -Iv.

Edit 2:

OK, I'm running this command:

strace -o /tmp/foo.out curl -Iv https://test.sagepay.com

This will dump out strace to /tmp/foo.out. Looking at the strace file for any mentions of "ssl", I see:

$ grep ssl /tmp/foo.out 
open("/lib/libssl.so.0.9.8", O_RDONLY)  = 3
stat("/etc/ssl/certs/7651b327.0", {st_mode=S_IFREG|0644, st_size=834, ...}) = 0
open("/etc/ssl/certs/7651b327.0", O_RDONLY) = 4
stat("/etc/ssl/certs/7651b327.1", 0x7fffbef10f20) = -1 ENOENT (No such file or directory)

That /etc/ssl/certs/7651b327.0 certificate is what's being used to validate the test.sagepay.com one. Following that:

$ readlink -f /etc/ssl/certs/7651b327.0
/usr/share/ca-certificates/mozilla/Verisign_Class_3_Public_Primary_Certification_Authority.crt

Does /etc/ssl/certs/7651b327.0 exist on your system? Does /usr/share/ca-certificates/mozilla/Verisign_Class_3_Public_Primary_Certification_Authority.crt exist?

  • Although the error message says that you can use --no-check-certificate to skip the certificate check, cjc's suggestion is better than that because it's fixing the error rather than ignoring it.

  • That /etc/ssl/certs directory is not empty and the file /etc/ssl/certs/ca-certificates.crt exists, right? Generally, that directory should be full of symlinks to the actual cert files that live in /usr/share/ca-certificates/ and its subdirectories. That /usr/share/ca-certificates/ directory also exists and is readable by the user you're executing curl as?

  • The directory is not empty, lots of symlinks as you say to /usr/share/ca-certificates. Dir for /etc/ssl/certs and /usr/share/ca-certificates are both world readable. Even running sudo curl ... results in the same issue with the certificates. Mar 27, 2012 at 14:47
  • @GregSpiers, I updated with more commands. Note that I'm doing this on Lucid -- I don't have a 11.10 box lying around -- but I can't imagine this being very different between Lucid and Oneiric.
    – cjc
    Mar 27, 2012 at 14:56
  • @cjc Thanks, I've followed your example and updated my original question with the output. I agree, it shouldn't be that different between those two releases. Mar 27, 2012 at 15:07
