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.

ServiceNow – Azure DevOps Integration

The IT industry needs optimal efficiency in its enterprise, which is not an easy task. Traditional practices are still in use but are not beneficial as they can slow down the process considerably. So, here comes ServiceNow, which has become a complete packed solution for IT Industries.

ServiceNow is software based on the cloud, providing IT services for automating business tasks and their management. It uses Machine Learning technology to automate processes and create workflows.

Azure DevOps supports a collaborative culture and set of processes that bring together developers, project managers, and contributors to develop software. It allows organizations to create and improve products at a faster pace than they can with traditional software development approaches.

In this article, we will discuss, how to use ServiceNow effectively by integrating it with Azure DevOps. Continue reading “ServiceNow – Azure DevOps Integration”

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.

Split Tunneling Using OpenVPN

While working with a client, we needed to be connected with VPN all the time, it is when we noticed there was always a delay in response when browsing the internet on my system because all the traffic was going through a VPN tunnel to the VPN server located in the far region and this was the case for every employee working for that client. So, what is the solution for this if you are a cost-conscious company? You want minimal use of resources and improve overall network performance. You do split-tunneling, which we will be discussing in this blog, and how you can achieve it.

What is Split tunneling?

Split Tunneling is a powerful feature in OpenVPN that allows clients to decide which traffic should be sent through the VPN tunnel and which traffic should be sent directly to the Internet. This means that the client can choose to route only specific traffic through the VPN, such as traffic destined for a corporate network, while allowing other traffic to bypass the VPN. This can be useful for increasing the speed and reliability of internet access for certain types of traffic, and for conserving bandwidth on the VPN server.

Self-Hosted GitLab Migration – Part 1

In the IT industry, the need for migration can raise several questions in your mind. Like what will be migrated and what measures should be taken to perform the particular migration. And the major concern is whether there are any chances of losing data. Losing even a tiny fraction of the data in transition can impact the performance of the application. So, in that scenario there are several measures that need to be kept in our mind while performing any sort of migration is taking a backup of the data, software configuration, and if any plugin is required for the software so that should also be checked. Apart from that migration should always take place when the least traffic comes on the application.

So, recently we got a requirement where we had to upgrade a self-managed Gitlab Community Edition(CE) from 11.11 to the latest version i.e., 15.4.

While upgrading Gitlab to any other version you might face many problems related to incompatible versions. So, for a successful upgrade, we’ll discuss the GitLab requirements for the upgradation and will also share the analyses that we found while following through this blog post.
