a Windows or Linux workstation with Universal Management Suite (UMS) in version 5.07.100 or newer,
a Debian or Ubuntu Linux workstation for unpacking the *.deb package (can be the same as the Linux workstation hosting UMS),
a method to exchange files between the thin client and the workstation. While a USB pen or disk drive would do the trick, it is more convenient to have either a
Windows fileshare or
an NFS export
that you can access both from the thin client and the workstation in order to exchange files.
