I’m the Noob

and this is my story

If it’s Linux, why is it called Ubuntu?

It’s based on Debian

Ok, so Linux…

A bit like this…

At the time, it was Unity - now it’s Gnome

(the 3D modelling software)

Call me, maybe

โ€โ€๐Ÿ’โ€ ๐Ÿ“žโ€

Try a different flavour

(like crisps)

๐Ÿฆœ Budgie

๐Ÿ”ฎ Kbuntu

๐Ÿ‡จ๐Ÿ‡ณ Kylin

โšก Lubuntu

๐Ÿ•ฐ Mate

๐Ÿ“ฝ Studio

๐ŸŽจ Xubuntu

Ok, makes total sense!

My greatest struggle

Installing stuff


$ sudo ๐Ÿ“ฆ

Advanced Package Tool

$ sudo apt update

The Ubuntu package repositories

Basically a database of available packages that have been tested

Update your local database

$ sudo apt update

Upgrade your packages

$ sudo apt upgrade

Install a package

$ sudo apt install package

Need a specific version?

$ sudo apt install package=version

Need a newer version?


Personal Package Archive (PPA)

A method of distributing software to users, without requiring developers to undergo the full process of distribution in the main ubuntu repositories

- Ubuntu Wiki

Add the PPA to your package database

Then use apt to install and upgrade

Adding a PPA allows full root access to your system

Always trust who it’s from


Bit better than downloading and installing from a website

Not as secure as installing from the main Ubuntu repositories

It might break everything!


Ain’t no Party

Like a Linux Hierarchy


  • /

The Root

everything is a file

  • bin

Bin is for Binaries

pwd, mkdir, cat and systemctl

  • boot

Boot is for booting

static files for the bootloader.

  • dev

Dev is for devices.

  • etc

Etc like Betsy

Configuration files for system wide applications

  • home

Home is for home

For all your stuff like documents, pictures, projects etc.

  • lib

Lib is for Library

System shared libraries for booting and running commands in the root filesystem.

  • media

Media is for media

Where media gets mounted to. If you plug in a USB for example.

  • opt

Opt is for optional add-on software packages

Nicely packaged apps with all their bits and bobs in one place

The /usr Hierarchy


  • usr

Usr is not for user.

not user

More like user space

  • usr
    • bin

The primary directory for executables that are not needed for booting or repairing the system.

less, pkill, which

  • usr
    • lib

Libraries for packages installed that aren’t system dependant.

  • usr
    • local

locally installed software by the administrator

(probably you if it’s your machine)

  • usr
    • local
      • bin

These binaries are for local programs

Programs not managed by the distribution package manager

  • usr
    • share

Share is for Sharing’s Caring

Architecture-independent data like man pages and locale information

Also ASCII character tables

The Var Hierarchy


  • var

Var is for Variable Data Files

Temp files like log files

  • var
    • cache

Cache stuff

Cached data from applications to save IO speed

  • var
    • games

Games are for playing

Scores, levels and user specific game data

Want more?

$ man hier

For more words to put into a search engine.


it’s not you, it’s me



Using with anything other than Version 2.1.3 will cause unimaginable chaos to you and your family


Long Term Support

18.04.3 Bionic Beaver

Interim releases get newer features whilst still being somewhat stable

What if you want a new application?

Snaps have got you covered…


Snaps work across Linux on any distribution or version. Bundle your dependencies and assets, simplifying installs to a single standard command.


Snaps work independantly of the Ubuntu release cycle

$ sudo snap install package-name

“I’ve heard snaps are rubbish

blah blah blah

Getting stable releases with the newest features is hard

More people testing bleeding edge releases, reporting bugs and enabling telemetry

Where’s the Ctrl + Alt + Delete?

My quest to look cool be productive


If in doubt

  • Try turning it off and on again
  • Check what you’re running which
  • Check the version you’re running version
  • Ask someone! There’s a huge community of people who have probably had this problem before
  • Re-install! Keep everything backed up

Thank you

Let’s chat later


Special thanks to

๐Ÿ‘‹ Bye
