Extract the Ubuntu package on your Debian/Ubuntu Linux workstation in order to access its files:
Open a terminal emulator.
Change to the directory where you saved the Ubuntu package.
Create a directory to extract the files to: mkdir chromium-browser
Extract the package to the new directory: dpkg -x *.deb chromium-browser/
Run the following command to see how much space the package contents need in total (in MB): du -cms chromium-browser/* The total is 255 MB (your package may differ slightly). To be on the safe side let's memorize that we need approximately 400 MB of space for the CP contents.
