Ok Chris, this deb package must be a correct version of your system. If your use Ubuntu 64bit must include (x64). If you use 32bit must include (x86).
If include both, doesn't mattter. In the previous instructions, you typed 'XeroxOfficev5Pkg-Linuxx86_64-5.20.661.4684.sh', and it's not the same like a deb package. Deb package is ready to install, better than "extract". It's not a zip, rar or iso archives.
So lets do:
Connect to internet.
Open terminal:
sudo apt-get update
sudo dpkg -i
Next add a space and drag an drop your downloaded deb package. Something like this:
sudo dpkg -i '/home/youruser/Desktop/XeroxOfficev5Pkg-Linuxx86_64-5.20.661.4684.deb'
Press enter. Install deb package.In theory, it could be that the system download some extra libs and this complet the full process.
For better performance, reboot and try to look into your ubuntu menu if Xerox or similar is present. Don't desperate if not.
