How to Fix Low Disk Space Issues on Ubuntu Linux While using Ubuntu Linux, you may encounter various issues caused by insufficient storage space.  Over time, the system may become slower, software updates may fail, or files may no longer be saved properly. 1. Why Disk Space Runs Out on Ubuntu Ubuntu is designed to manage storage efficiently, but disk usage can increase gradually due to several factors: Cached files created during system updates Log files that grow continuously over time Snap packages storing multiple revisions Unused packages and dependencies left behind Large user files accumulated in the home directory These files often grow unnoticed until the system begins to show warning signs. 2. Checking Current Disk Usage The first step in resolving low disk space issues is understanding the current storage situation . 2.1 Check Overall Disk Usage Run the following command in a terminal: df -h This command displays total disk size, used space, an...

Essential Settings to Configure After the First Boot of Raspberry Pi OS


After completing the installation of Raspberry Pi OS and booting the system for the first time, there are several important settings that should be checked and configured before fully using the Raspberry Pi. 

This initial setup process has a significant impact on system stability, ease of use, and the overall learning and development environment. 

In particular, for users who are new to Raspberry Pi, carefully going through these steps will help them understand how to configure and use both the operating system and the Raspberry Pi system itself.



1. Verify Language, Region, and Keyboard Layout Settings

During the initial boot process, users are asked to select language, region, and keyboard layout settings. However, these settings are not always configured correctly.

You can review and adjust them by navigating to:

  • Preferences → Control Centre

Key items to check include:

  • Language

  • Timezone

  • Keyboard Layout

Incorrect settings may cause issues with terminal input or system time synchronization.

2. Perform a Full System Update

Immediately after installation, the Raspberry Pi OS image may not be fully up to date. Running a system update should be one of the first steps.

Open a terminal and execute the following commands:

sudo apt update
sudo apt full-upgrade

This ensures that security patches, bug fixes, and driver improvements are applied, resulting in a more stable system.



3. Change the Default User Password

For security reasons, it is strongly recommended to change the default user password, especially if the Raspberry Pi will be connected to a network.

You can change the password using the following command:

passwd

Choose a password that is not overly simple while still being easy to remember.

password command
password command



4. Check Wi-Fi and Network Configuration

If you plan to use the Raspberry Pi with a wireless network, verify that the Wi-Fi connection is stable. 

If the signal is weak, consider adjusting the device’s location or using a wired Ethernet connection.

It is also useful to check the assigned IP address, particularly for remote access or server-related tasks.

ip addr




5. Enable SSH for Remote Access

SSH is essential if you want to manage your Raspberry Pi remotely or use it without a monitor.

To enable SSH:

  • Preferences → Control Centre

  • Go to the Interfaces tab

  • Enable SSH

Once enabled, you can remotely access the Raspberry Pi from another computer using a terminal.

6. Adjust Display Resolution and Screen Settings

Depending on the monitor being used, the screen resolution may not display correctly, or parts of the screen may be cut off.

You can adjust these settings under:

  • Preferences → Control Centre

  • Go to Screens tab

Proper display settings improve readability and reduce eye strain during extended use.

7. Configure Boot Options and Auto Login

Depending on whether you plan to use a graphical desktop or a command-line interface, adjusting boot options can be beneficial.

You can choose between:

  • Console auto login

  • Desktop auto login

  • Manual login options

For server or experimental use, booting directly into the console may be more appropriate.

8. Install Basic Development Tools and Packages

Since Raspberry Pi is commonly used for learning and development, installing essential tools in advance can save time later.

Commonly used packages include:

  • Git

  • Python development tools

  • build-essential

Example command:

sudo apt install git build-essential

These tools are frequently required for software development and project work.

install git build-essential



9. Prepare a Backup Strategy and Create an Initial Snapshot

The point at which initial setup is complete is an ideal time to create a system backup. Backing up the entire SD card as an image allows for quick recovery if issues arise later.

This is especially useful for learning or experimental environments where system settings may change frequently.



10. Conclusion

After the first boot following the installation of Raspberry Pi OS, carefully completing the settings introduced above will help you build a more stable and efficient Raspberry Pi environment.

Regardless of whether the Raspberry Pi is used for learning, development, or server purposes, properly configuring the initial settings is extremely important. 

Establishing a solid foundation at the beginning will make all future tasks much smoother and easier to manage.

Understanding Computer System In the digital age, computers have become essential tools used across many fields. A computer is built on two core components: hardware and software . Understanding how these two elements are structured and how they operate helps users manage and operate computers more effectively. 1. What is Computer Hardware? Computer hardware refers to the physical, tangible parts of a computer system.  These are the components you can touch and see.  Without hardware, a computer would have no structure to run programs or process data. 1.1 Main Types of Hardware Input Devices – Tools that allow you to send information to the computer. Examples: Keyboard, mouse, scanner, microphone. Output Devices – Components that deliver processed information to the user. Examples: Monitor, printer, speakers. ...

Understanding System Software The computer programs we use operate on top of an essential layer of software known as system software , which makes all tasks possible. System software manages hardware resources, provides an environment in which application programs can run, and plays a critical role in ensuring that the entire computer system functions smoothly and reliably. 1. What is System Software? System software is a set of programs designed to operate, control, and extend the processing capabilities of the computer itself.  Unlike application software, which performs specific user tasks, system software manages the hardware and provides a platform for applications. The main purpose of system software is to act as a bridge between the user applications and the physical hardware of the computer. 2. Types of System Software System software can be broadly categorized into several key types: 2.1 Operating System (OS) The operating system is the m...

Understanding Operating Systems (OS) An Operating System (OS) is the most important software on any computer.  It acts as a bridge between the user and the computer hardware, managing resources and providing an environment for other software to run.  1. What is an Operating System? An Operating System is a collection of software that manages computer hardware and software resources.  It controls the CPU, memory, storage devices, input/output devices, and coordinates their operation.  The OS enables users and applications to communicate with hardware in an efficient and user-friendly way. 2. Main Functions of an Operating System Process Management: The OS manages running programs (processes), allocating CPU time, and ensuring smooth multitasking. Memory Management: It handles RAM allocation, keeping track of each application’s memory use and optimizing system perfor...
