Linux Mint Update Failed

Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/c/cifs-utils/cifs-utils_7.0-2ubuntu0.3_amd64.deb 404 Not Found [IP: 2606:4700:10::6814:1cf6 80]

How to fix

Update Your Repository List

Run the below command to clean cache and update the list of available packages:

sudo apt clean -y
sudo apt update -y

Then use the Update Manager, reresh it, and try installing again.

This fixed it for me.
