Objectives

By the end of this course, participants will be able to prepare, deploy and maintain a Debian desktop estate to replace Windows, and set up a useful everyday Debian server (files, printing, light directory). Training runs on Debian. A session on Ubuntu (and Ubuntu LTS server) can be arranged on request; the programme stays the same.

Audience and context

For teams driving a Windows exit (local authority, public body, SME). Goal: operational autonomy: clean installs, light industrialisation, safe updates, documentation so the estate does not depend on one person.

Programme

Day 1: Debian foundation and a reference workstation

  • Mapping a Windows → Linux migration: desktops, scope, blocking apps, phasing
  • Debian: releases, support, desktop vs server, why we use it in training
  • Guided workstation install (BIOS/UEFI, partitions, user, sudo)
  • apt packages: search, install, update, purge, repositories and good practice
  • Users, groups, permissions, sudoers: mental model for an IT estate
  • Basic networking: IP, DNS, optional proxy, diagnostics (ip, ss, journal)
  • Workshop: build a minimal “staff workstation” image (desktop, browser, LibreOffice, IT tools)

Day 2: Desktop fleet, printing, identity

  • Repeatable deployment: preseed / golden image, cloning checklist, first-boot pitfalls
  • Printing and scanning (CUPS): print servers, drivers, user rights
  • Joining the existing world: local accounts vs directory (LDAP / Active Directory Linux clients)
  • File shares: SMB/CIFS on the client, mounts, permissions, business folder cases
  • Updates and lifecycle: unattended-upgrades, maintenance windows, pragmatic rollback
  • Desktop security: disk encryption overview, lock screen, basic firewall, service accounts
  • Workshop: “10 desktops for one department” (deploy, print, share, user account)

Day 3: Useful server, operations and migration plan

  • First Debian server: hardened SSH, updates, minimal monitoring (logs, simple alerts)
  • Light virtualisation with KVM/QEMU: why test desktops and servers in VMs before the real estate
  • Backups: what to save (user data, configs), frequency, restore test
  • Inventory and documentation: what to write so a replacement can take over
  • Remaining Windows business apps: strategies (web, container, app VM, open source alternative)
  • Build your migration plan: pilot, end-user training, go-live criteria, rollback
  • Final workshop: staged roadmap for your organisation (or a typical authority / SME case)

Method

Heavy hands-on on VMs. Bring a list of business apps and printers if you can: we use them as the thread. Recommended group size: 4 to 8 people.
