cPanel Installation problem – Detected an installer lock file Error

Symptoms: While performing sh latest command the system stuck with an error message about installer.lock.

Beginning main installation.

Detected an installer lock file (/root/installer.lock).

Please be sure that an installer is not already running.

Resolution:

You can remove the installer.lock file using this command via ssh

rm -rf /root/installer.lock

This problem arises while installing cPanel when an installation running on the same server is present or if an installer.lock file is existing in your /home directory where you are trying to install the cPanel. You just need to remove the existing installer.lock file and re-run the command sh latest which will proceed the installation smoothly.
