Unpacking the Packages
In this step, you extract the packages on your Linux workstation in order to access their files:
Open a terminal.
Change to the directory where you saved the packages.
Create a directory to extract the files to:
mkdir teams
Extract the packages to the new directory:
dpkg -x teams*.deb teams/
Run the following command to see how much space the package contents need in total (in MB):
du -cms teams/*
The total is 237 MB (your package may differ slightly). To be on the safe side, let's memorize that we need approximately 500 MB of storage space for the Custom Partition contents.
