When deploying openvz images, we use a init-script to delete puppets ssl directory and then run a curl that deletes the certificate from the puppet server:

curl -k -X DELETE -H "Accept: pson" ""`.

After upgrading to puppet 3.5.1 this stopped working, I have read that I need to revoke the certificate first and that works:

curl -k -X PUT -H "Content-Type: text/pson" --data '{"desired_state":"revoked"}'

I have verified that the certificate gets revoked on the server:

[root@puppet ~]# puppet cert list
- "" (SHA256) A9:FD:2D:C3:E4:7C:84:12:9C:D0:B2:4C:F2:81:AB:A0:BE:9C:A4:40:A7:8E:4A:6A:D8:E0:A4:D7:10:A9:4B:E2 (certificate revoked)

After this, the documentation says that I should run the DELETE command described above but that fails (using | sed for readability):

curl -k -X DELETE -H "Accept: pson" | sed 's/,/\n/g'
"message":"Server Error: undefined method `each' for nil:NilClass"

Hmm, you could try and run the master with --trace, see if that yields another backtrace, because I disbelieve that the trace from the agent side can help getting to the bottom of this one.

Running the master with 'puppet master --trace --no-daemonize --debug --verbose' did not produce any more output than in the example above.

You may wish to raise this as a bug then.

Update: This has been fixed in version 3.6.1.

Adding DELETE in, as suggested by Paul Beltrani in issue PUP-2516, /usr/lib/ruby/site_ruby/1.8/puppet/network/http/route.rb (CentOS 6) solved the issue for me.

+      :PUT => [MethodNotAllowedHandler],
+      :DELETE => [MethodNotAllowedHandler]
     @chained = []

Now I can delete the certificate on the puppet master from the client using curl:

[root@client ~]# curl -k -X DELETE -H "Accept: pson"
"Deleted for Puppet::SSL::Certificate"
