You can remove this file and re-run the cPanel installation process after you are certain that another installation is not already in progress.

I saw the above error while trying to install cPanel control panel on my CentOS server. Error shows that there might an installer already running on your server. Type the command “ps auxwf” to check whether any cPanel installation is going on. “ps auxwf” command will list all process running on your linux server. You can remove the lock file /root/installer.lock and re-run the cPanel installation process after you are certain that another installation is not already in progress. You can remove the installer lock file using the below command
Command : rm -f /root/installer.lock
After removing the lock file you can start cPanel installation and you wont see the same error. Run the below command to restart cPanel installation.
Command : cd /home && curl -o latest -L https://securedownloads.cpanel.net/latest && sh latest
cPanel installation will take 20-50 minutes, depending on your server hardware.
