Solution 2 – Incorrect raspi-config PATH Settings:

Check your PATH variable by typing echo $PATH in the terminal. If /usr/bin is missing, you need to add it. You can temporarily add it to your PATH by running export PATH=$PATH:/usr/bin, but for a permanent fix, add this line to your .bashrc file in your home directory.

If you’re encountering the “sudo raspi-config command not found” error even after installing raspi-config, it’s possible that the command’s directory isn’t included in your system’s PATH environment variable. The PATH variable tells the shell where to look for executable files. Here’s how to check and set the proper PATH settings for raspi-config:

Step 1 – Locate raspi-config:

First, find out where raspi-config is installed. It’s usually in /usr/bin/. You can use the which command to locate it:

which raspi-config

If it returns a path like /usr/bin/raspi-config, note it down.

Step 2 – Check Current PATH:

To see your current PATH settings, type:

echo $PATH

This command will display a list of directories separated by colons.

Check if the directory where raspi-config is located (e.g., /usr/bin) is in the list. If it’s not, you’ll need to add it to your PATH.

Step 3 – (Temporary Method) Add Directory to PATH:

To temporarily add the directory to your PATH for the current session, use:

export PATH=$PATH:/usr/bin

Replace /usr/bin with the directory you found raspi-config in if it’s different.

Step 3 – (Permanent Method) Add Directory to PATH:

For a permanent solution, you need to add the directory to your PATH in your bash profile. Edit your .bashrc file in your home directory (~/.bashrc) using a text editor, like nano:

nano ~/.bashrc

Add the following line at the end of the file –

export PATH=$PATH:/usr/bin

Again, replace /usr/bin with the correct directory if it’s different. Save and close the file (in nano, press Ctrl+X, then Y, and Enter).

Step 4 – Reload .bashrc or Reboot:

For changes to take effect, either reload your .bashrc file:

source ~/.bashrc

Or reboot your Raspberry Pi:

sudo reboot

Step 5 – Test the Configuration:

After setting the PATH, test to see if raspi-config can be accessed:

sudo raspi-config

The raspi-config interface should open without the “command not found” error.

Solution 3 – User Permissions Issues:

This issue is less likely to cause the specific error in question, but ensuring you have the correct permissions is always a good practice. Running raspi-config with sudo (as in sudo raspi-config) is necessary because it requires root permissions.

Method 1 – Using Sudo

To execute raspi-config, you need superuser (root) access. This is typically achieved using the sudo command in Linux, which stands for “superuser do”. By prefixing a command with sudo, you are instructing the system to run that command with superuser privileges.

To run raspi-config, you should use the following command in the terminal:

sudo raspi-config

Instead of just raspi-config.

User Account with sudo Privileges: To use sudo, your user account must be part of the sudo group. On Raspberry Pi OS, the default user ‘pi’ is already configured with these privileges. If you’re using a different user account, you might need to add that user to the sudo group.

Method 2 – By Switching to Root User

Open Terminal: Start by opening a terminal window.

Switch to Root User using either of the below commands:

For a Root Shell (similar to logging in as root): Type sudo -i and press Enter. This will provide an environment similar to what you would get if you logged in as the root user directly.

For a Root Shell Keeping Your Environment: Type sudo -s and press Enter. This opens a shell with root privileges but retains your user’s environment variables.

When prompted, enter your current user’s password (the user must have sudo privileges).

Now try to run raspi-config in the terminal directly.

Proceed with Caution: Now you’re operating as the root user. Be very careful with the commands you run in this mode.

Solution 4 – Corrupted or Incomplete OS Installation:

Reinstall the Raspberry Pi OS. Use a reliable SD card and ensure a stable power supply during the installation to prevent corruption. After the installation, update and upgrade the system (sudo apt update and sudo apt full-upgrade) to ensure all packages are up to date.

Solution 5 – Outdated System:

Update your Raspberry Pi OS to the latest version. Run sudo apt update to update your package lists, followed by sudo apt full-upgrade to upgrade all installed packages. This process should also update raspi-config.

Solution 6 – Damaged Filesystem or SD Card:

If your SD card is damaged or the filesystem is corrupted, the most reliable solution is to get a new SD card and reinstall the Raspberry Pi OS on it. Always safely shut down your Raspberry Pi to avoid such damage.

Solution 7 – Conflicts with Custom Configurations or Scripts:

If you suspect that custom scripts or configurations are causing the problem, try to revert those changes. If you’re unable to pinpoint the exact issue, a fresh installation of Raspberry Pi OS might be the most straightforward solution. In the future, be cautious with scripts and configurations that might affect system settings.

In each of these scenarios, the key is to methodically assess and address the specific cause of the error. Regular system maintenance, careful configuration management, and ensuring a stable environment for your Raspberry Pi can help prevent such issues.
