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

As a Linux user, especially those who use Ubuntu, you may have encountered an issue where the lastlog command displays all users as "Never logged in". This can be frustrating, especially when you know that most of the users are actual user accounts and not system accounts. In this article, we will explore the possible causes of this issue and provide solutions to fix it.

lastlog is a command-line utility in Linux that displays the last login information for each user account on the system. It is a useful tool for system administrators to track user activity and identify potential security issues. However, when lastlog displays all users as "Never logged in", it can be a sign of a problem with the system's login history or the user account configuration.

There are several possible causes of the "Never logged in" issue in lastlog. Some of the most common causes include:

  • System accounts: System accounts, such as root, syslog, and messagebus, are not intended for user login. These accounts are used for system-level tasks and do not have a login history.
  • User account configuration: User account configuration issues, such as incorrect or missing login history, can cause lastlog to display "Never logged in".
  • Login history corruption: Corruption in the login history database can cause lastlog to display incorrect or incomplete information.
  • Virtualization: Using virtualization software, such as Oracle VirtualBox, can cause issues with the login history and lastlog command.

To troubleshoot the "Never logged in" issue in lastlog, follow these steps:

Step 1: Check System Accounts

System accounts are not intended for user login, so it's normal for them to display "Never logged in" in lastlog. However, if you're seeing actual user accounts displayed as "Never logged in", it's worth checking the user account configuration.

getent passwd

This command will display a list of all user accounts on the system, including their login history. Check the output to see if any of the user accounts have a login history.

Step 2: Check Login History Corruption

Corruption in the login history database can cause lastlog to display incorrect or incomplete information. To check for corruption, run the following command:

lastlog -f

This command will display the login history in a format that's easier to read. Check the output to see if there are any errors or inconsistencies.

Step 3: Check Virtualization

If you're using virtualization software, such as Oracle VirtualBox, it's possible that the login history is not being updated correctly. To check for this, try running the following command:

lastlog -f | grep -v "Never logged in"

This command will display the login history for all users, excluding those who have never logged in. Check the output to see if there are any users with a login history.

Step 4: Rebuild Login History

If you've checked for corruption and virtualization issues, and you still seeing "Never logged in" in lastlog, it's possible that the login history needs to be rebuilt. To do this, run the following command:

lastlog -f -r

This command will rebuild the login history database.

The "Never logged in" issue in lastlog can be caused by a variety of factors, including system accounts, user account configuration, login history corruption, and virtualization. By following the troubleshooting steps outlined in this article, you should be able to identify and fix the issue. Remember to always check the user account configuration and login history database for errors or inconsistencies.

  • Use lastlog with caution: lastlog can be a powerful tool for tracking user activity, but it can also be used to track system administrators. Use it responsibly and only for legitimate purposes.
  • Check the login history regularly: Regularly checking the login history can help you identify potential security issues and prevent them from becoming major problems.
  • Use lastlog with other tools: lastlog can be used in conjunction with other tools, such as last and wtmp, to provide a more complete picture of user activity on the system.
