Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 5847 (aptd)

Question

I was trying to install git in my Ubuntu 22.04.3 LTS.

After using "sudo apt update" command.
I used "sudo apt upgrade -y" cmd.
Then it displayed this message -> "Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 5847 (aptd)"

Are you sure you don't have another window/terminal waiting for you to respond to a question? Alternatively it could be system background updates, but that will resolve itself shortly anyway. — guiverc, Feb 01 '24 at 05:50
Does this answer your question? E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) — guiverc, Feb 01 '24 at 06:25
Does this answer your question? Unable to lock the administration directory (/var/lib/dpkg/) is another process using it? — Artur Meinild, Feb 07 '24 at 06:34

Error Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend says that your operation sudo apt update probally is not finished. Check for process with id 5847 by running in terminal ps -p 5847. You will see what process prevents you from upgrading. You can wait until it finishes, but if you are sure that it is a mistake, you can restart your laptop or pc and lock error will disappear, so you can continue installing git. But I strongly recommend to wait until previous operation is finished.
