Installing singularity in ubuntu 20.04

SingularityCE is a container platform. It allows you to create and run containers that package up pieces of software in a way that is portable and reproducible. 

You can build a container using SingularityCE on your laptop, and then run it on many of the largest HPC clusters in the world, local university or company clusters, a single server, in the cloud, or on a workstation down the hall.

Your container is a single file, and you don’t have to worry about how to install all the software you need on each different operating system.

In short, singularity is an alternative to docker.
