Verify Your Ubuntu Download

You downloaded Ubuntu (open source software operating system) and now want to verify that the image you have is authentic and not tampered with.

Here’s how you can do that:

First you will need to get the checksum for the version you downloaded by visiting the webpage
–> Ubuntu 18 SHA256SUMS
–> Ubuntu 16 SHA256SUMS

Open terminal (CTRL-ALT-T) and go to the folder where you have the Ubuntu file

Example:

cd Downloads

Here’s the command to verify your file:

echo "xxxxxxxxxx" | shasum -a 256 --check

Make sure you replace xxxxxxxxxx with the version you downloaded

Example:

echo “add4614b6fe3bb8e7dddcaab0ea97c476fbd4ffe288f2a4912cb06f1a47dcfa0 *ubuntu-18.04.3-desktop-amd64.iso” | shasum -a 256 --check
