Errors while installing updates

[sachinjr]

Hi, I am not able to install updates on to my system,  I am seeing these errors:

E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 2544 (apt-get)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

My system information: Can someone help?
