Resolving Lastlog Keep Displays All Users as "Never logged in" in Ubuntu

As a Linux user, especially those who use Ubuntu, you might have encountered an issue where the lastlog command displays all users as "Never logged in". This can be frustrating, especially when you're trying to troubleshoot user login issues or monitor system activity. In this article, we'll explore the possible causes of this issue and provide step-by-step solutions to fix it.

lastlog is a command-line utility in Linux that displays the last login time for each user account on the system. It's a useful tool for system administrators to monitor user activity, detect potential security threats, and troubleshoot login issues. However, when lastlog displays all users as "Never logged in", it can be challenging to determine the root cause of the problem.

There are several reasons why lastlog might display all users as "Never logged in". Some possible causes include:

System accounts: System accounts, such as root, syslog, and nobody, are not typically used for user login. These accounts are used for system-related tasks, and their last login times are not updated.
User account configuration: User account configuration issues, such as incorrect shell settings or missing home directories, can prevent lastlog from displaying the correct last login time.
File system issues: File system issues, such as corrupted or missing files, can prevent lastlog from functioning correctly.
Virtualization: If you're using a virtualization platform like Oracle VirtualBox, there might be issues with the virtual machine's file system or configuration that affect lastlog.

To resolve the issue, follow these step-by-step troubleshooting steps:

Step 1: Check System Accounts

System accounts are not typically used for user login, so it's not surprising that they're displayed as "Never logged in". You can ignore these accounts and focus on resolving the issue for actual user accounts.

Step 2: Verify User Account Configuration

To verify user account configuration, follow these steps:

Check shell settings: Ensure that the shell setting for each user account is correct. You can use the getent command to verify the shell setting for each user account:

getent passwd | grep -v "system" | awk '{print $1, $7}'

This command will display the username and shell setting for each user account. 2. Check home directory: Ensure that the home directory for each user account exists and is correctly configured. You can use the ls command to verify the existence of the home directory for each user account:

ls /home/

This command will display a list of user accounts with their corresponding home directories.

Step 3: Check File System Issues

To check for file system issues, follow these steps:

Check file system integrity: Use the fsck command to check the integrity of the file system:

fsck -f /

This command will check the file system for any errors or inconsistencies. 2. Check for corrupted files: Use the find command to search for corrupted files:

find / -type f -size +1M -print

This command will display a list of files that are larger than 1MB.

Step 4: Check Virtualization Issues

If you're using a virtualization platform like Oracle VirtualBox, there might be issues with the virtual machine's file system or configuration that affect lastlog. To troubleshoot virtualization issues, follow these steps:

Check virtual machine configuration: Ensure that the virtual machine's configuration is correct. You can use the VBoxManage command to verify the virtual machine's configuration:

VBoxManage showvminfo "Ubuntu"

This command will display the virtual machine's configuration. 2. Check file system configuration: Ensure that the file system configuration for the virtual machine is correct. You can use the VBoxManage command to verify the file system configuration:

VBoxManage showvminfo "Ubuntu" --details

This command will display the file system configuration for the virtual machine.

Resolving the issue where lastlog displays all users as "Never logged in" can be challenging, but by following the troubleshooting steps outlined in this article, you should be able to identify and fix the root cause of the problem. Remember to check system accounts, user account configuration, file system issues, and virtualization issues to ensure that lastlog is functioning correctly.

Use lastlog with the -u option: To display the last login time for a specific user account, use the lastlog command with the -u option:

lastlog -u username

This command will display the last login time for the specified user account.

Use last command: To display a list of user logins, use the last command:

last

This command will display a list of user logins, including the username, login time, and logout time.

By following these tips and troubleshooting steps, you should be able to resolve the issue where lastlog displays all users as "Never logged in" and ensure that lastlog is functioning correctly.
