Programs like login, shutdown, uptime and others want to read from and write to the /var/run/utmp, /var/log/btmp and /var/log/wtmp. These files contain information about who is currently logged in. They also contain information on when the computer was last booted and shutdown and a record of the bad login attempts. Create these files with their proper permissions by running the following commands: touch /var/run/utmp /var/log/{btmp,lastlog,wtmp} && chmod 644 /var/run/utmp /var/log/{btmp,lastlog,wtmp}
