requests-kerberos | authentication handler for using Kerberos | Reactive Programming library

I'm using Packer to build an ami with a file ami.json that runs two provisioners built off the default Ubuntu Server 20.04 LTS image. The problem is Packer build randomly fails on apt-get install ansible with the error E: Unable to locate package ansible. The same ami.json file builds or doesn't build intermittently despite zero changes.

It seems potentially related to this question from 5 years ago that got a workaround but not a real answer: Packer/Amazon EBS/Ubuntu - Inconsistent PPAs

I'm trying to rollout directories, users and standard software over ansible on windows systems. To do so I've created a role which will handle that for me. Now I've two environments: 1 dev environment with two Windows Server 2016 VM's and 1 QA environment with two Windows 2016 Server VM's.

The role is the same, only the vm's are others.

When I execute my role on the dev environment side everything works fine. All tasks for windows systems can be executed.

Here are my entries in dev host file for ansible:

In an otherwise stable environment, when I call cluster.connect(), the code just hangs indefinitely, no errors or timeout messages. The connection is contained inside a Nameko service. I suspect it is related to the Nameko service code, particularly the monkey patching involved, since the otherwise identical code works fine outside of a Nameko service. I should note this only seems to be a problem with Python 3.7 and Cassandra 3.18. With Python 3.6 and Cassandra 3.16, this works fine. Here is a code snippet:

I am on RHEL. I Installed python by following https://www.rosehosting.com/blog/how-to-install-python-3-6-4-on-centos-7/. I am getting an error when trying to install requests-kerberos

I have an environment.yml and I have two dependencies that are only windows. Is there a tag I can add to not install this package in the environment.yml?

I've tried adding the [win] tag after the dependency in the environment.yml and that causes the installation to fail.

I am deploying a docker solution for my application. In my docker file I used multiple conda-forge to build some containers. It worked very well for some of the containers, and give an error for the other and I am sure it is not about the package, because for the same package sometimes it work and others no.

I have tried to use pip instead of conda, but that lead to other errors since I am using conda originally for all of my configuration. Also, I read that RUN conda update --all will solve it, and for pip setup RUN pip install --upgrade setuptools

This is part of my docker file :

I have an Node.js app with Python scripts that I am trying to deploy to Heroku.

Every time I try to add the heroku/python buildpack the git push gets rejected.

remote: Could not find a version that satisfies the requirement pywin32==224 (from -r /tmp/build_ebad00f3b8d3c9b4b03965f0d0924e7a/requirements.txt (line 57)) (from versions: ) remote: No matching distribution found for pywin32==224 (from -r /tmp/build_ebad00f3b8d3c9b4b03965f0d0924e7a/requirements.txt (line 57))

error: failed to push some refs to 'https://git.heroku.com/xxxxx.git'

Without the heroku/python buildpack the push works fine. I think I need that buildback for my Python scripts work on web.

My app runs fine locally but everything related to Python is not working when deployed. I use Python 3.7.3 64-bit version. I have runtime.txt and requirements.txt in root of my app.

My runtime.txt file:

As I understand, the current java.net.URL handshake (for a GSS/Kerberos authentication mode) always entails a 401 as a first leg operation, which is kind of inefficient if we know the client and server are going to use GSS/Kerberos, right? Does anyone know if preemptive authentication (where you can present the token upfront like in the python one https://github.com/requests/requests-kerberos#preemptive-authentication) is available in the java world?

A quick google points towards https://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html but the preemptive example seems to be for the Basic scheme alone.

Thanks!

I have been trying to install pywinrm module on my Ansible control server which is running on RHEL 6 with Python 2.6 (pre-installed).

But the dependency cryptography module fails with the error :
