In this comprehensive guide, we will delve into the process of resolving the
cifs mount error on Ubuntu Server 20.04 running on Raspberry Pi 4. This error typically manifests as “mount error(2): No such file or directory” and indicates that the mount command cannot locate the specified directory or file.
- Understanding the Issue
- Solution 1: Verify the Directory Path
- Solution 2: Confirm the IP Address and Shared Directory
- Solution 3: Install cifs-utils
- Solution 4: Check Network Connectivity
- Solution 5: Specify the Domain/Workgroup
- Solution 6: Check Firewall Settings
- Solution 7: Check Kernel Log Messages

Understanding the Issue
Before we proceed with the solutions, it’s crucial to understand the root of the problem. The
cifs mount error can occur due to various reasons, including incorrect directory paths, network connectivity issues, missing
cifs-utils package, and firewall settings.
Solution 1: Verify the Directory Path
First, ensure that the directory you’re trying to mount exists on your Ubuntu Server. For instance, if the directory is
/home/ubuntu/windowshare, confirm its existence. If it doesn’t exist, create it using the
mkdir command is used to create a new directory.
Solution 2: Confirm the IP Address and Shared Directory
Next, verify the IP address and the name of the shared directory on your Windows machine. Ensure they are correct and accessible from the Ubuntu Server.
Solution 3: Install cifs-utils
cifs-utils package provides tools and utilities for mounting SMB/CIFS shares. Confirm that it is installed on your Ubuntu Server. If not, install it using:
sudo apt-get install cifs-utils
sudo command allows you to run the command as a superuser,
apt-get is the package handling utility in Ubuntu, and
install is used to install the specified package.
Solution 4: Check Network Connectivity
Ensure that your Raspberry Pi 4 has a stable network connection to the Windows machine. You can test the connectivity using the
ping command sends network requests to the specified IP address and returns if the host is reachable.
Solution 5: Specify the Domain/Workgroup
If your Windows machine is part of a domain or workgroup, you may need to specify it in the mount command. For example:
sudo mount.cifs //192.168.0.5/SharedDirectory /home/ubuntu/windowshare -o user=myusername,password=mypass,domain=mydomain
-o option allows you to specify several filesystem-specific options as a comma-separated list. In this case, we’re specifying the
Solution 6: Check Firewall Settings
Verify that the firewall on your Windows machine isn’t blocking the connection. Try temporarily disabling the firewall or adding an exception for the necessary ports (e.g., TCP port 445) to see if it resolves the issue.
Solution 7: Check Kernel Log Messages
Examine the kernel log messages using the
dmesg command to get more information about the error. Look for any relevant error messages related to CIFS or network connectivity.
dmesg command is used to print and control the kernel ring buffer, a data structure that records information about the system’s operation.
If none of these solutions work, consider providing more information about your network setup, Windows version, and any relevant log files to further diagnose the issue. Remember, troubleshooting is a process of elimination. Be patient, and you’ll eventually find the solution.
For more information about the
cifs-utils package, you can visit the official Ubuntu documentation. For more details on how to use the
mount.cifs command, refer to the man page.
cifs mount error is an error that occurs when the mount command is unable to locate the specified directory or file for mounting. It is commonly displayed as "mount error(2): No such file or directory".
You can check if a directory exists on Ubuntu Server by using the
ls command followed by the directory path. For example, to check if the directory
/home/ubuntu/windowshare exists, you can run the command
ls /home/ubuntu/windowshare. If the directory exists, it will be listed in the output.
You can install the
cifs-utils package on Ubuntu Server by running the command
sudo apt-get install cifs-utils. This command will download and install the required package from the Ubuntu repositories.
You can view the kernel log messages on Ubuntu Server by using the
dmesg command. Simply run the command
dmesg in the terminal, and it will display the kernel log messages related to system operation.
You can find more information about the
cifs-utils package by visiting the official Ubuntu documentation. The documentation provides detailed information about configuring Windows networking on Ubuntu Server.
You can find more details about using the
mount.cifs command by referring to the man page. The man page provides a comprehensive guide on the usage and options of the
