Explains the shopping server operating system

While a software program may communicate directly with hardware, most programs are written for an operating system, allowing them to use shared libraries and not worry about specific hardware details. Ubuntu operating system Ubuntu OS is one of the reported operating systems we want to explain in this article.

In this regard, the operating system acts as a comprehensive framework with which all applications can interact consistently, greatly simplifying the entire development process.

Examples of operating systems include:

Some operating systems were developed in the 1950s when computers could only run one program at a time. Later in the decade, computers included many software programs, sometimes called libraries, that were linked together to create the beginnings of today’s operating systems.

The operating system consists of many components and features. Which features are defined as part of the operating system varies from operating system to operating system.

What does Ubuntu mean?

Is an open-source operating system (OS) based on the Debian GNU/Linux distribution? Ubuntu is a GNU/Linux distribution based on Debian, which is almost entirely made up of free software. Ubuntu is currently released in Desktop and Workstation editions. All scripts can be run alone on a computer or virtual machine.

It adds all the features of a Unix operating system with a customizable graphical user interface, making it popular in universities and research organizations. The operating system is primarily designed for PC use, although there is also a server version.

Ubuntu is an African word that means “humanity for others.”

Ubuntu was first released in 2004. The project is sponsored by Canonical Ltd., a UK-based company that generates revenue by selling support and services to complement Ubuntu. Canonical releases a new version of Ubuntu every six months, followed by 18 months of support in patches and security releases.

Ubuntu includes many software packages licensed under the GNU General Public License. It allows users to copy, modify, develop, and redistribute their application version.

Ubuntu has a wide range of software programs, including Firefox and LibreOffice. There is also dedicated software that can run on Ubuntu.

What does Ubuntu Snappy mean?

Ubuntu Snappy is a package manager initially developed by Canonical for the Ubuntu Phone distribution. The ” snaps ” packages are designed to work on various Linux distributions, not just Ubuntu. This project aims to create universal packages that work on any distribution, independent of any app store.

Ubuntu Snappy attempts to create a “universal package manager” for Linux distributions. SNAPPY replaces current package management systems such as APT or RPM. With conventional package management systems, packages must be adapted from upstream source code. Some distributions make significant changes to the legend, making it difficult to contribute to the developers of the original open-source project.

Under Snappy, packages are labeled “snaps.” Snaps have no dependencies, making installing Snaps on distributions other than Ubuntu possible. While Snappy is in the Ubuntu app store by default, other repositories may be used. Snaps are also designed to be lightweight, and only changes to a single image or deltas are installed on the system during an upgrade.

Snappy was initially designed for Ubuntu Touch but is available on major distributions, including Debian, Fedora, CentOS, and Arch Linux.
What does Ubuntu Server mean?

Ubuntu Server is part of the more extensive suite of Ubuntu products and operating systems developed by Canonical Ltd. Ubuntu Server is a special add-on slightly different from Ubuntu Desktop to facilitate server installation.

In the following tables, we have written the minimum hardware to run this versions and their flavors. It is also better not to have an Nvidia graphics card because the manufacturer does not support the Linux kernel. After all, you will face problems.

The table below shows the minimum hardware specifications of Ubuntu versions and flavors. These specifications do not provide Ubuntu’s best performance, and you may experience slowness. The versions mentioned in the table above and not below do not have information about their minimum hardware requirements.

  1. Ubuntu Dual Core 1Ghz 1GB 20GB
  2. Ubuntu Mate Core i2 Dou 1 GB 8 GB
  3. Visually stunning, wherever it is used

Ubuntu gets the most out of your screen with high resolution, touchscreen support, fractional scale, and touchpad gestures. 22.04 updates Yaru’s signature theme with support for the system-wide preferred dark style, bold colors, and the largest community wallpapers ever.

Get Linux on the most extensive range of hardware.

Canonical works closely with Dell, Lenovo, and HP to verify that Ubuntu works on their range of laptops and workstations. This means a seamless Ubuntu experience with more hardware choices than ever.

And Ubuntu isn’t just for desktops; it’s used in data centers worldwide, powering every kind of server imaginable, and is by far the most popular operating system in the cloud.

Ubuntu desktop for enterprise
Support and management tools

Ubuntu Pro Desktop is a comprehensive subscription that provides enterprise-grade security, management tools, and extensive support for developers and organizations. Ubuntu Pro Desktop is free for personal use on up to five devices.

Canonical is a global software company and the number one provider of Ubuntu services. Companies can get training, support, or expert advice for a fee that pays for the ongoing development of Ubuntu.

How to enable root access in Ubuntu?
For root access in Linux, it is enough to enter the sudo -I command:

sudo -i

After entering this command, the command line will ask us for the primary user’s password (Super User). By entering the password and pressing the Enter button, the access mode will change to the Root user.
How to change the root password?

To set a new password for the root user, you can use the sudo passwd root command:

Sudo passwd root

After entering this command, the command prompt will ask you to enter the new password. After entering the new password, press the Enter button:

Enter new UNIX password:
Then re-enter the command line to confirm the new password.

After entering the new password, press the Enter button:Retype new UNIX password:

With the su root command, you can enter the root user account with the new password.

su root

How to restrict root access?

You may have to temporarily hand over your Linux server to someone else, and you don’t want them to have access to everything. Therefore, if root access is enabled, you must turn it off.

For this purpose, you must enter the following command sudo passwd -l root:

Sudo password -l root

How to root a user in Ubuntu?

When creating a new user in Linux, you must first enter the terminal with the root user to be allowed to do this. As we said in the above paragraph, to log in with the root user, you must first enter the command sudo -i in the command line and then enter its password to give you root access.
2. In the next step, you can create a new user with the adduser command:

Add user username

In this command, enter your desired username instead of username; For example, add user azaronline; Every user in Linux must have a password. So in the next step, the command prompt will ask you for a new password for the new user. Enter your desired password and then press Enter.

Enter new UNIX password:
It will then ask you to re-enter the password to confirm the password: Retype new UNIX password:

After re-entering the desired password, press the Enter button to create a new user.

After creating a new user, enter the following command to make it a root user or so-called (Super User):

usermod -aG sudo username

In this command, enter your desired username instead of username; In the next step, you need to add the new user to the sudoers list.

To do this, first, open the sudoers list in the terminal with the nano command so that it can be edited in the nano editor (nano is a text editor similar to NotePad in Windows, with which you can edit text files):

Sudo nano /etc/sudoers

Now you need to add the following line to the sudoers list:

username ALL=(ALL) ALL

In this line, instead of a username, enter your desired username; Finally, save this list by pressing Ctrl + O. If you want to exit the nano editor, you can press Ctrl + X.

Finally, to use the new user you created, enter the following command:

su – username

By entering the above command, the terminal command line will ask you for the password.
