Installing Articles 1.6: xPDOVehicle validator failed

I've tried to update from 1.4.7 to 1.5.1 and 1.6.0. However, in both cases the install failed.
In the latest failure, I got the attached results. I would love to retain the existing articles! How can I upgrade without losing them?
It starts with:

Console running...

See if there's something in the MODX error log (on the Reports menu) around the time of the error.

I ran into the same issue. Then I realized it was because Articles 1.6 requires MODX 2.2.1 and I am running 2.2.0.

Unfortunately the package does not validate whether you are running the required version of MODX. Not sure if that's possible.

I try new test install 2.2.1 pl + articles 1.6 , not work properly ,4 error and not show the content container template
I try custom template in my prod site and the error in +tags and no show content but show the simple article alone good.

Thanks for the responses!

1. The error.log contains errors referring to allow_url_fopen (see below). That is enabled (and I haven't had problems installing other packages). I believe this is a known issue with Articles but this was happening before, when Articles 1.4.7 was working.

2. I am running 2.2.0 -- so I guess I should try to upgrade, if what lukemcd says is correct. I had the same or very similar error trying to install 1.5, though. Did that also depend on 2.2.1?

Regarding updating, it seems I should untar the modx package over the existing installation, making sure not to overwrite config.inc.php or the core/components/ directory. Anything else I should be careful about?

Meanwhile, the site is unavailable, so I'm trying to deal with this as quick as I can!

Here are the errors, which I don't think are the problem in this case:

Make sure your core/packages directory is writeable and has the correct ownership.

I got a similair error when upgrading from 1.5.1 (installing this gave errors) to 1.6.0.
Core/packages is writable. Ownership is set by hostingprovider (I can not change that, other packages installed without problems from scratch).

Please look at the attachment.
If you need more information, just let me know.

I've got the exact same error...

I upgraded to 2.2.1 and that fixed the problem.
Thanks lukemcd!

I just installed the latest version of MODX Revolution 2.2.4-pl (traditional) and want to use Articles to create a blog. Unfortunately I'm running into this same error. I'm new to revolution so I don't know where to go from here.

Help would be much appreciated.
