Error on running with python3: "ModuleNotFoundError: No module named 'ConfigParser'" and the fix

[MurzNN]

When I'm trying to log in using howdy in Ubuntu 23.04 which has python3 version by default - I've got an error:

2023-06-11T07:45:01.786521+04:00 Ubuntu /lib/security/howdy/pam.py[25199]: ModuleNotFoundError: No module named 'ConfigParser'

I've searched for similar issues already, and my issue has not been reported yet.

Linux distribution (if applicable): Ubuntu 23.04

Howdy version (sudo howdy version): 2.6.1

The 'ConfigParser' library in python3 is renamed to configparser, so the fix is to change the current code in file /usr/lib/security/howdy/pam.py like this:

@@ -6,11 +6,17 @@ import os
 import glob
 import syslog
 
-# pam-python is running python 2, so we use the old module here
-import ConfigParser
+import sys
+# The config parser is named in python2 as ConfigParser but in python3 as configparser
+# and here is a workaround for this.
+if sys.version_info[0] == 2:

 # Read config from disk
-config = ConfigParser.ConfigParser()
 config.read(os.path.dirname(os.path.abspath(__file__)) + "/config.ini")

I've found that the similar changes already implemented in the dev branch: https://github.com/boltgolt/howdy/blob/dev/src/pam.py#L10-L15

So, @boltgolt could you please make a new release with these changes?

Same exception here after updating ubuntu to 23:04, the suggested changes do solve the issue
