My Debian Bookworm Installation

This is my installation of Debian Bookworm. This will use sway for window manager. This is a very minimal installation.

Downloading the iso File

Downloading Debian from the official Debian website is straightforward. Here's a step-by-step guide to help you:

1. Open the Debian Home Page: Go to debian.org.
2. Click Download Button: On the homepage, you should see a prominent Download button or link.

Buring the iso file

The dd command in Linux is a powerful utility for low-level copying and conversion of data. To burn an ISO image to a disk (such as a CD or DVD) using dd, follow these steps. Be very careful with dd, as it can overwrite any drive, potentially leading to data loss if used incorrectly.

1. Identify the Target Device: First, you need to identify the correct device file for your target disk. You can list the available disks and their partitions using lsblk or fdisk -l.

lsblk

Look for a device that corresponds to your CD/DVD drive or USB drive (e.g., /dev/sdX or /dev/sr0).

2. Unmount the Device (if necessary): If the device is mounted, unmount it before proceeding. Replace /dev/sdX1 with your actual partition if it's mounted.

sudo umount /dev/sdX1

3. Use dd to Write the ISO Image: Execute the dd command to write the ISO image to the device. Replace /path/to/your.iso with the path to your ISO file and /dev/sdX with your target device (make sure it's the whole device, not a partition).

sudo dd if=/path/to/your.iso of=/dev/sdX bs=4M status=progress

• if (input file) specifies the path to your ISO image.
• of (output file) specifies the target device.
• bs=4M sets the block size to 4 megabytes (adjust if needed).
• status=progress shows the progress of the operation.

4. Sync and Wait: After dd completes, it's a good idea to sync the disk to ensure all data is written.

sudo sync

5. Eject the Disk (if necessary): If you're burning to a CD/DVD and want to eject the disk, you can do so with:

sudo eject /dev/sdX

Example Command:

sudo dd if=debian.iso of=/dev/sdb bs=4M status=progress

Notes:

• Double-check the device path (/dev/sdX) to ensure you're writing to the correct disk. Mistakenly writing to the wrong device can erase important data.
• dd does not perform error checking or verification on the written data. If you need to verify the integrity of the written disk, you can use additional tools like md5sum or sha256sum to compare checksums.

By following these steps, you should be able to burn an ISO image to a disk using dd.

Boot the Pendrive

Boot the iso from Boot Menu.

You need to find your boot menu key for your device.

Installing Debian

Install the Debian based on your requirement. In Software Selection Screen select nothing. And then click Continue.

First Boot

Reboot the device and login as root. The perform update by typing the command:

apt update && apt upgrade -y

Debian does not install sudo by default. So you need to install sudo. To install sudo you need to type:

apt install sudo --no-install-recommends

Then reboot the os with:

reboot

Add user in sudo

Now we need to add user in sudo list. So, first we need to login as root. Then type the command below to add user as root:

sudo usermod -a -G sudo <username>

After adding user to sudo we need to reboot. Type

reboot

Login as user

After logging in as user we need to check whether sudo is working or not. To check if sudo is working we need to type the following command:

sudo apt update && sudo apt upgrade -y

If the command works then the sudo is working.

Adding Auto Login

If we want to auto login to our user then we can type the command:

sudo systemctl edit getty@tty1

Then add the following lines after the line that says Anything between here and the comment below will become the new contents of the file:

[Service]
ExecStart=
ExecStart=-/sbin/agetty --autologin <username> --noclear %I 38400 linux

Time Sync

To sync time we need to install systemd-timesyncd. To install systemd-timesyncd we need to type the following command:

sudo apt install systemd-timesyncd --no-install-recommends

Sway

Sway is a window manager.

Installing Sway

To install sway we need to type the following command:

sudo apt install sway --no-install-recommends

Autostart Sway

Add the following lines in ~/.profile file:

if [ -z "$WAYLAND_DISPLAY" ] && [ -n "$XDG_VTNR" ] && [ "$XDG_VTNR" -eq 1 ] ; then
    exec sway
fi

Installing Terminal

We will install foot terminal. To install foot we need to type the following command:

sudo apt install foot --no-install-recommends
