PHP Update - 7.2.13 to 7.4 or higher

Question

I have a Bitnami WordPress 5.0.3-2 site running on AWS Lightsail / Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-1096-aws x86_64). The WordPress dashboard is telling me I need to update the PHP version which is currently 7.2.13 to a minimum Ver. 7.4. I have tried following several step-by-step instructions that I found on the web but in each case, things failed at some point in the process. I'm a novice so I need fairly detailed instructions. Can somebody point me in the right direction?

Thanks for your help!
