Unable to install version > 3.6.1 on Ubuntu 18.04 using python 3.7 after module update #374

svenboll · 2022-11-03T14:26:38Z

We are using puppetboard for almost 2 years now and switched from vcsrepo to pip installation method a few weeks ago.
But after all i don't see a newer version installed than 3.6.1.
First i figured out that on Ubuntu 18.04 the python version installed is 3.6 by default and with puppetboard version 4 the support for python3.6 was removed.
So i decided to use parameter python_version => '3.7', but nothing happened. We are still on version 3.6.1 of puppetboard.

After all, the venv-python directory did not update to python3.7 as expected and is still on python3.6.

So i removed the entire directory /srv/puppetboard/virtenv-puppetboard
puppet sets up a new virtual env with python3.7 (now as expected), but the version of our visible puppetboard was still running on version 3.6.1 and not as seen in the logs with version 4.2.0

Affected Puppet, Ruby, OS and module versions/distributions

Puppet: 7.18
Ruby: 2.5.1
Distribution: Ubuntu 18.04
Module version: this=9.0.0 / puppet-python=6.3.0

How to reproduce (e.g Puppet code you use)

Code with vcsrepo installation method (using module version 8.2.0):

class { 'puppetboard':
    default_environment => '*',
    manage_git          => true,
    manage_virtualenv   => true,
    revision            => 'v3.6.1',
  }

  class { 'puppetboard::apache::vhost':
    vhost_name => $facts['fqdn'],
    port       => 80,
  }

After switching to pip installaton method our code looks like (using module version 9.0.0):

  class { 'puppetboard':
    default_environment => '*',
    manage_virtualenv   => true,
    python_version      => '3.7',
  }

  class { 'puppetboard::apache::vhost':
    vhost_name => $facts['fqdn'],
    port       => 80,
  }

What are you seeing

Puppetboard version 3.6.1 with old virtualenv directory including python3.6:

After creating a new virtualenv directory with python3.7 i see the following puppetboard. Still on version 3.6.1 but without the graph of failed, changed or unchanged puppet runs!

Output log

puppet run after removing directory /srv/puppetboard/virtenv-puppetboard :

Any additional information you'd like to impart

I don't look at other directories or files relating to apache, wsgi apache module or something else right now.

Hi @svenboll, thanks for reporting the issue.

Changing python_version value on an existing installation is not working because last time I checked the puppet-python module did not support changing this version on the fly...

Sorry for the stupid question but did you (or Puppet) restart Apache/Puppetboard after removing the virtualenv and letting Puppet recreate it?

svenboll · 2022-12-06T09:03:19Z

Hi @gdubicki ,
i've tested restarting apache2 after recreating the virtualenv, but then i get an "500 - Internal Server Error"

gdubicki · 2022-12-06T15:26:35Z

You should find the root cause of this 500 in apache2 logs. Can you share it please?

svenboll · 2022-12-08T08:23:38Z

could this be a wsgi update/plugin error?
so, these are the actions and error log outputs:

Thanks for that info!

I suspect that the puppetboard package did not install for you in the new virtualenv that used Python 3.7, but the error was suppressed and not shown.

You should check the pip.log at /srv/puppetboard/virtenv-puppetboard, of course for the new Python 3.7 virtualenv.

And while most probably it's the puppetboard package itself, you can also compare the whole list of packages with this good working list from one of my instances on a Centos 7 node using Python 3.8:

# . /srv/puppetboard/virtenv-puppetboard/bin/activate
(virtenv-puppetboard) # pip freeze
certifi==2022.6.15
charset-normalizer==2.1.0
click==8.1.3
commonmark==0.9.1
Flask==2.1.3
Flask-WTF==1.0.1
idna==3.3
importlib-metadata==4.12.0
itsdangerous==2.1.2
Jinja2==3.1.2
MarkupSafe==2.1.1
packaging==21.3
puppetboard==4.2.2
pyparsing==3.0.9
pypuppetdb==3.1.0
requests==2.28.1
urllib3==1.26.10
Werkzeug==2.1.2
WTForms==3.0.1
zipp==3.8.1

If any of the packages is missing, even if you don't see any errors in the log, you can try to install them manually while having the virtualenv activated and see what are the results of that.

Please share all the findings!

svenboll · 2022-12-12T13:46:18Z

So i tested now python 3.7 and python 3.8 venv with the same result of installed packages, and after all i still ended up in "500 - Internal Server Error":

with both python3.7 and 3.8 virtenv there are some suspicious errors in the pip.log:

gdubicki · 2022-12-14T13:48:29Z

The notreallyaversion string comes from the puppet-python module, it's not an issue here.

gdubicki · 2022-12-14T14:10:18Z

Can you please check the WSGI config in your Apache vhost, @svenboll ?

Maybe for some reason you don't have the virtualenv configured there.

For example I have something like this in my /opt/rh/httpd24/root/etc/httpd/conf.d/25-<redacted>.conf:

  ## WSGI configuration
  WSGIDaemonProcess puppetboard group=puppetboard python-home=/srv/puppetboard/virtenv-puppetboard request-timeout=180 threads=10 user=puppetboard
  WSGIProcessGroup puppetboard
  WSGIScriptAlias / "/srv/puppetboard/puppetboard/wsgi.py"

svenboll · 2022-12-14T14:45:25Z

it looks the same for me on my apache vhost conf.

i think it could be a similar issue to #369

in my apache2 module folder i can only find these entries related to mod_wsgi, no version for python 3.7 or 3.8 which are the versions i tested. could this be a problem?

/usr/lib/apache2/modules:
lrwxrwxrwx 1 root root        15 Jul 25 15:24 mod_wsgi.so -> mod_wsgi.so-3.6
-rw-r--r-- 1 root root 237168 Jul 25 15:24 mod_wsgi.so-3.6

gdubicki · 2022-12-14T18:02:13Z

You are totally right, it seems related to that... You should have mod_wsgi for Python 3.7 or 3.8, whatever you are using. I am not sure how can you get it on Ubuntu though.

We are using Centos 7 and Python 3.8 and HTTPD 2.4 from SCL. The HTTP 2.4 is mainly to have a mod_wsgi working with that Python 3.8. We install it using this code:

  class { 'apache::mod::wsgi':
    package_name => 'rh-python38-python-mod_wsgi',
    mod_path     => 'modules/mod_rh-python38-wsgi.so',
  }

I hope that it helps!
