Hello,

In this week’s feature highlight, we look at How to Install Ubuntu 22.10

Ubuntu is one of the most popular Linux distributions out there that is based on Debian and composed mostly of free and open-source software.

In this article, we will learn how to install Ubuntu 22.10 on a server.

Login to Crownpanel

Login to your CrownPanel account.

To start the installation, First, mount the Ubuntu 22.10 ISO.

To mount the ISO, click on CD-ROM and then select the “ubuntu 22.10 server amd64” ISO from the drop-down menu and click on the “Mount” button (It will take 2-3 minutes).

Once the ISO has mounted (the Task Log tab will show the status of the task), navigate to the “Power Control” tab and then perform a Reboot task on the server.

Next, Switch to the “VNC” Tab, Launch VNC to start the installation.

If VNC doesn’t show the Ubuntu 22.10 installer, please click on CTRL+ALT+DEL from the VNC console to send a reboot.

Start the Installation

Select the desired language and click on continue.

At the time of writing this article, there were no updates on the installer but later on, you may be prompted to update the installer in case there is a new version available. This is a recommended option to update it.

Select the desired keyboard layout and click on done.

Select the Network configuration and click done.

You can either set up a static network configuration or simply go ahead with DHCP (Simply press ENTER here).

You can configure a proxy for the server in this part of the process if needed. Ideally, in most cases you don’t need to, just leave it blank and proceed.

Next, in the mirror selection, we keep the default mirror address that Ubuntu detects for us,

Disk partitioning, we will keep it simple and go with automatic partitioning. Select the “Use an entire disk” option and continue.

Review the “partitions” and then proceed.

Since we’re installing a new operating system on the existing disk, you will be prompted to lose data on the selected disk. Confirm and select “Continue”.

Profile setup, You will be provided a form to enter your user information. These will be the login details that we’ll use later to connect to the server.

We will choose the package OpenSSH server to be installed as it is essential if you need to connect remotely after the installation.

The Ubuntu 22.10 installer also has other packages available for pre-install, you can pick any you wish to pre-install on your server, in this guide we will keep it at a bare minimal (ie, no extra packages selected),

At this stage, Ubuntu will start the installation of the disk.

Once the installation is complete, go ahead with the reboot.

After you select to reboot the VPS, Ubuntu will prompt you to unmount the installation medium.

To unmount the ISO, switch back to CrownPanel, Select the “CD-ROM” tab and click on “Unmount”.

Next, switch back to the VNC Window, and press ENTER to reboot the VPS,

The VPS will then reboot into your installation of Ubuntu 22.10

This completes the installation of Ubuntu 22.10

You can now log in to the server using the credentials that were set earlier (under the “Profile setup” part of this guide)

Check the Hostname using the below command,

hostnamectl

Sample Output:

crown@crown:~$ hostnamectl
 Static hostname: crown
       Icon name: computer
      Machine ID: 98ef1ad056e345ba99622d140a2f234e
         Boot ID: 1344ac34c125487080c6d75976753fc1
  Virtualization: kvm
Operating System: Ubuntu Kinetic Kudu (development branch)
          Kernel: Linux 5.19.0-21-generic
    Architecture: x86-64
 Hardware Vendor: Red Hat
  Hardware Model: KVM
Firmware Version: 0.5.1

We will then update the Ubuntu system with the below commands,

sudo apt update

sudo apt dist-upgrade

Once the updates are installed, we will push the server for a reboot to apply any modifications.

reboot

Done! You are now ready to use the Ubuntu 22.10 server as you like.

Hello,

In this week’s feature highlight, we look at How to Install Python 3.10 on Rocky Linux 9

Python is an interpreted high-level general-purpose programming language. Its design philosophy emphasizes code readability with its use of significant indentation. Its language constructs as well as its object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.

First, check for any pending system updates,

dnf update

Install required packages.

dnf install gcc openssl-devel bzip2-devel libffi-devel zlib-devel wget make

Install Python 3.10.5

By default, Rocky Linux 9 comes with Python version 3.9

In this article, we will install the latest version of Python that is available, 3.10.5, on the Rocky Linux 9 system. You can check their official website to find the latest version available and download its source code.

wget https://www.python.org/ftp/python/3.10.5/Python-3.10.5.tgz 

Extract the downloaded file.

tar xzf Python-3.10.5.tgz 

Change to the extracted directory with the following command.

cd Python-3.10.5 

Run configuration command.

./configure --enable-optimizations 

Complete the Python installation on the Rocky Linux system by running the following command.

make -j 2

nproc

make altinstall 

Once the Python has been installed, confirm the version that is available by,

python3.10 --version

Output:

[root@server Python-3.10.5]# python3.10 --version
Python 3.10.5

Using pip on Python 3.10.5

Check the installed version of a pip by running the following command,

pip3.10 -V

Output:

[root@server ~]# pip3.10 -V
pip 22.0.4 from /usr/local/lib/python3.10/site-packages/pip (python 3.10)
