Problem installing mos tool on Ubuntu 21.04

I am trying to install the mos tool on Ubuntu 21.04 according to the quickstart guide. I have tried the instructions for ubuntu which tells me to run:

sudo add-apt-repository ppa:mongoose-os/mos
sudo apt-get update
sudo apt-get install mos

As well as the instructions for Generic MacOS/Linux which tells me to run:

curl -fsSL | /bin/bash

However, I always end up getting the the following:

Package mos is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'mos' has no installation candidate

Has anyone encountered the same problem and could point me in the right direction? Are there any alternative ways to install the tool?

Answering my own question here.
I found out that the correct package name is mos-latest.
In other words,

sudo apt install mos-latest

will install the mos tool.

Support for Ubuntu 21.04 is available only in mos-latest.
