How to Fix a Corrupted GUI after Downgrading Python on Ubuntu?

If you’ve recently downgraded Python on Ubuntu, you may have noticed that your GUI is not functioning properly. Specifically, the login screen may be corrupted or not loading at all, and you may not be able to log in or access your desktop. This is because the downgrade may have caused some dependencies to break, including the lightdm package that manages the display manager.

What is Lightdm ?

Lightdm is a display manager that manages the login screen and desktop environment for Ubuntu and other Linux distributions. It’s responsible for starting the X server, authenticating users, and loading the graphical user interface. If lightdm is not functioning properly, you may not be able to log in or access your desktop. Reinstalling lightdm is a simple and effective solution to fix these issues and restore your system’s GUI.

Downgrading Python can cause unexpected issues with your system, particularly with the graphical user interface (GUI). Specifically, the display manager known as lightdm may become corrupted, resulting in an unusable login screen and desktop environment.

Cloud Migration: The Key to Scaling Your Organization

As the global wave of cloud migrations and cloud platform engineering practices have gathered pace and scale, the early cloud adopters and fast followers have reaped the benefits of speed, agility, scalability and cost savings that the cloud offers.

In this article, we will discuss, how to use ServiceNow effectively by integrating it with Azure DevOps.

Prerequisites for Integration

An Azure DevOps organization. Create an organization, if you don’t have one already.
A non-developer instance of ServiceNow.

Configure the ServiceNow instance

Install the Azure Pipelines extension on your ServiceNow instance. You’ll need Hi credentials to complete the installation. See Buying Overview for more details on installing apps from the ServiceNow store.
Create a new user in ServiceNow and grant it the following role: x_mioms_azpipeline.pipelinesExecution.

The Power of Docker Images: A Comprehensive Guide to Building from Scratch

Docker has revolutionized the way we build and deploy applications. It provides a platform-independent environment that allows developers to package their applications and dependencies into a single container. This container can then be easily deployed across different environments, making it an ideal solution for building and deploying applications at scale.

Building Docker images from scratch is a must skill that any DevOps engineer needs to acquire for working with Docker. It allows you to create custom images tailored to your application’s specific needs, making your deployments more efficient and reliable.

Here, in this blog, we’ll explore Docker images, its benefits, the process of building Docker images from scratch and the best practices for building a Docker image.

Introduction to Azure Active Directory

Introduction:

In organizations, employees often need access to various Azure services to perform their tasks. They can use services like SQL database or Azure container services when the system administrator assigns them a user id and password for each service. However, managing multiple user logins for each service can be a hassle for administrators, especially in organizations with over 1000 employees. Azure Active Directory (AD) helps solve this issue by enabling administrators to manage multiple user logins in a centralized manner.
