I am getting this error when trying to upgrade:

E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.15_all.deb  Hash Sum mismatch

To check what is wrong I downloaded the package from the address and checked the md5 which is showing something different in my machine from the one given on the website.

That generally means that the download was corrupted. Try the following to remove the downloaded file and retry the upgrade:

sudo apt-get clean
sudo apt-get upgrade

As an addendum to the previous answer:

Delete your local copy of the file. Choose a different apt mirror (to prevent caching of the corrupt download by some transparent proxy) and retry.
