Git repositories store valuable source code and are used to build applications that work with sensitive data. If an attacker was able to compromise a GitHub account with a vulnerable repository, they could push malicious commits straight to production. Signed commits help ensure that doesn’t happen.

Most PC Game Pass and Microsoft Store games are UWP apps, meaning you can’t add them to Steam as non-Steam games the usual way. But there’s a working method, and it includes downloading and running a third party app.

The Ubuntu login loop is a frustrating problem that makes it impossible for you to log in. We describe six different issues that can cause this behavior and how to fix them.

What Is a Login Loop on Ubuntu?

The Ubuntu login loop is a problem that returns you to the login screen instead of logging you in and presenting you with your desktop. It’s as if your credentials are being rejected, but that’s not the case. It’s just not letting you in. Even though you’re definitely typing in the correct user name and password, you’re bounced right back to the login screen.

Of all the possible problems with a computer, not being able to log in is one of the scariest. If you can’t get in, how can you fix it? Thankfully, Linux provides us with more than one way to log in, and we can leverage that to our advantage in this scenario.

Actually, this problem can happen to other distributions as well. It seems to have been tagged the “Ubuntu login loop” because there’s an impression that it’s reported on computers running Ubuntu more frequently than on other distributions. I suspect that’s because there’s more computers running Ubuntu Linux than any other distribution.

The system administrator role includes creating users, deleting users, and reviewing existing users. They also control who can, and cannot, use root‘s elevated powers. Here’s how to do that on Ubuntu Linux.

What to Know About Managing Users in Ubuntu

Multi-user systems require a distinct user account for each person who uses the computer. Each users has their own password, and their own private area for data. Normal users cannot access another user’s data. The root user can access anything, of course.

It’s the root user who manages user accounts. They must create an account when a new user needs to use the computer, and they delete old accounts when they’re no longer required.

Apart from creation and deletion, other changes may be required during the lifetime of the account. The user may forget their password, and need it to have it reset. They may join another department or team and need to be added to the appropriate user group. They may even be promoted and be awarded root privileges. These common tasks fall on the system administration team. If you’re the administrator on duty—or the only one in the team—you’re expected to complete these tasks quickly and easily.

Here’s a round-up of how to carry out these common tasks on Ubuntu. Because they use standard tools, you can use them on other distributions too, but we’ll be featuring Ubuntu in the screenshots.

Why Use the Command Line?

The command line came long before graphical desktop environments appeared. It was the primary way to use and administer Unix, the operating system that Linux is based on.

There are hundreds of commands available on the Linux command line, and many of these have dozens of options. This delivers granularity, power, speed, and flexibility. The trouble is, that blinking cursor in a terminal window isn’t welcoming, and the prospect of learning all of those commands and options can be overwhelming to the newcomer.

Standard Ubuntu installs don’t include the Linux make utility. It’s used mainly by software developers, but even non-coders may need it in some situations. Here’s how to install make on Ubuntu Linux.
