Hi everyone.

I’m in the middle of moving our Passbolt server from a dedicated box to a VM on another server. We’ve been running it on the dedicated box for about a year and love it. The packages are about as 1:1 as we could get.

CentOS 7.7, PHP 7.2.24, MariaDB 10.3.20, NGINX 1.16.1

I copied everything from /var/www/passbolt on server 1 to server 2 with rsync over ssh.

When I first ran healthcheck it was reporting that I hadn’t imported the key and a few permissions issues, which I fixed by running their recommended commands. However, now I’m only down to issues with not having an SSL certificate on the site yet and it still says “Could not verify server key. The OpenPGP server key defined in the config could not be found in the GnuPG keyring.”. On the right, in the login area it says “Oops! Something went wrong” but there’s nothing new in the error logs.

Saw another similar issue where he mentioned time problems which apparently I had forgotten about, but after adjusting the server to the same timezone as the other the problem persists.

In my config file I have:

    'passbolt' => [
        // GPG Configuration.
        // The keyring must to be owned and accessible by the webserver user.
        // Example: www-data user on Debian
        'gpg' => [
            // Main server key.
            'serverKey' => [
                // Server private key fingerprint.
                'fingerprint' => '35E9DFA05FCD47B7F4F78EE4576A68950CDDEFED',
                'public' => CONFIG . DS . 'gpg' . DS . 'serverkey.asc',
                'private' => CONFIG . DS . 'gpg' . DS . 'serverkey_private.asc',
            ],
        ],

and when I run su -s /bin/bash -c "gpg --fingerprint" nginx I get:

    /var/cache/nginx/.gnupg/pubring.gpg
    -----------------------------------
    pub   2048R/0CDDEFED 2018-11-28
        Key fingerprint = 35E9 DFA0 5FCD 47B7 F4F7  8EE4 576A 6895 0CDD EFED
    uid                  360bolt <achamberlain@fakeemail.com>
    sub   2048R/A35C10CF 2018-11-28

So seems like the same key as my old server, and indeed, the healthcheck seems to think so as well.

The output of sudo -u nginx ./bin/cake passbolt healthcheck also doesn’t contain any errors related to the key.

Hello,

Can you check if the web server is using the same keyring than the cli by forcing the location of the keyring in the config:

'gpg' => [
            'keyring' => '/var/cache/nginx/.gnupg',
            'putenv' => true,

Another direction I would check is if you have SELinux enabled, if there any error with Nginx not being able to interact with gnupg agent.

Thanks.

SELinux is currently set to Disabled for debugging.

I added this to my ./config/passbolt.php file:

    'passbolt' => [
        // GPG Configuration.
        // The keyring must to be owned and accessible by the webserver user.
        // Example: www-data user on Debian
        'gpg' => [
            'keyring' => '/var/cache/nginx/.gnupg',
            'putenv' => true,
            // Main server key.
	    'serverKey' => [
                // Server private key fingerprint.
                'fingerprint' => '35E9DFA05FCD47B7F4F78EE4576A68950CDDEFED',
                'public' => CONFIG . DS . 'gpg' . DS . 'serverkey.asc',
                'private' => CONFIG . DS . 'gpg' . DS . 'serverkey_private.asc',
            ],
	],

and then ran ./bin/cake cache clear_all in case that was the issue.

Also just made sure that the PHP GPG packages were there with pecl list:

Installed packages, channel pecl.php.net:
=========================================
Package Version State
gnupg   1.4.0   stable
mcrypt  1.0.3   stable

Are you still seeing this issue? If yes can you show the permissions for the .gnupg directory and permissions for the content inside?

aaronc · December 4, 2019, 9:17pm

Thanks here’s the output for /var/cache/nginx:

[root@localhost passbolt]# ls -al /var/cache/nginx/
total 32
drwxr-xr-x  8 root  root  4096 Dec  4 00:08 .
drwxr-xr-x. 8 root  root  4096 Dec  2 15:00 ..

and then for .gnupg:

[root@localhost passbolt]# ls -al /var/cache/nginx/.gnupg/
