mssql-tools is already the newest version (17.5.2.1-1).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
mssql-tools : Depends: msodbcsql17 (>= 17.3.0.0) but it is not going to be installed
unixodbc-dev : Depends: unixodbc (= 2.3.7)
Depends: odbcinst1debian2 (= 2.3.7) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I tried following the dependency failure tree to install unmet dependencies manually but in the final step failed to install:
sudo apt-get install multiarch-support
Reading package lists... Done

Reading state information... Done
Package multiarch-support 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 'multiarch-support' has no installation candidate
How would you solve these issues to finally install the Command line?

Answer 1

Using:
curl https://packages.microsoft.com/config/ubuntu/20.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.list
Instead of:
curl https://packages.microsoft.com/config/ubuntu/18.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.list
Solves the issue, The docs are out dated or maybe Ubuntu 20.04 is not officially supported yet...
Also I wasn't able to use curl https://... (Don't know why always peer closed my connection!) so I manually downloaded the link and paste the result to /etc/apt/sources.list.d/msprod.list
