Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend)

This error usually occurs when another process is using the `dpkg` package management system, preventing you from acquiring the lock required to perform operations such as installing or removing packages.

To resolve this issue, you can try the following steps:

1. Make sure there are no ongoing package management processes:

   sudo lsof /var/lib/dpkg/lock-frontend

If any processes are listed, you can terminate them using `kill` command followed by the process ID.

2. If the above step doesn't work, you can remove the lock files:

   sudo rm /var/lib/dpkg/lock-frontend
   sudo rm /var/lib/dpkg/lock

After removing the lock files, you should be able to run `dpkg` commands without any issues.

3. In some cases, a system reboot may be necessary if the lock files persist even after removing them.

Remember to use these commands with caution and ensure that you have appropriate permissions while executing them.
