Ubuntu Setup after Installation

Every once in a while I setup a new Ubuntu VM and I have to redo all these steps. This will help me speed things up.

VM Specifications

  • RAM: 4GB.
  • VGA memory: 128MB (max) in VirtualBox and 1GB in VMWare.
  • Enable 3D acceleration.
  • Disk space: 30 or 40GB.

Install Virtualization Plugins

These allow clipboard copy/paste and sometimes even drag/drop.

VirtualBox

  1. If the VM does not have a CD-ROM, shut it down, add one and launch.
  2. Load the guest additions ISO: Devices > Insert Guest Additions CD Image....
  3. Navigate to the mounted drive.
  4. Run sudo ./VBoxLinuxAdditions.run.
  5. Enable:
    • Devices > Shared Clipboard > Bidirectional.
    • Devices > Drag and Drop > Bidirectional.
      • Dropped files will be in /tmp/VirtualBox Dropped Files and the directory is deleted on boot.
  6. Restart.
  7. Profit.

VMWare

  1. sudo open-vm-tools open-vm-tools-desktop.
  2. Restart.
  3. Shared clipboard will work, not sure about files.

Set Keyboard Shortcuts

Set at System Settings > Keyboard > Shortcuts.

  • Custom Shortcuts > New - Name: terminal - Command: gnome-terminal - Key: Super+R.
  • Navigation > Hide all normal windows - change to Super+D. Works after logout.

Install Useful Packages

Some packages are not installed by default.

sudo apt-get update
sudo apt-get install curl git libltdl-dev 

Disable Screenlock and Screensaver

No reason to have them in a VM.

Settings > Brightness & Lock: - Set lock to off. - Turn screen off when inactive for: Never.

Install Go 1.10

Current golang package is not up to date.

  1. sudo apt-get update.
  2. sudo apt-get install golang-1.10.
    • This will install go in /usr/lib/go-1.10/.
  3. I don’t like the default GOPATH (/home/$USER/go). I prefer files to be on desktop.
    • mkdir -p /home/$USER/Desktop/Go/{src,bin,pkg}.

Edit .bashrc

Inb4 that’s not the correct way to do this.

Set GOROOT and new GOPATH to PATH: - export PATH="/usr/lib/go-1.10/bin:/home/$USER/Desktop/Go/bin:$PATH". - export GOPATH="/home/$USER/Desktop/Go".

Navigate to Desktop in every new terminal (this will cause errors if terminals are opened in other paths):

  • cd Desktop.

Apply settings with:

  • source ~/.bashrc.

Install VS Code

Electron app, so be sure to download more RAM assign lots of RAM to VM.

Copied from official instructions:

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'
sudo apt-get update
sudo apt-get install code

Install Docker - Optional

Instead of using the docker.io package through aptitude, use the official instructions at:

sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo apt-key fingerprint 0EBFCD88 # This might change in the future

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

sudo apt-get update

sudo apt-get install docker-ce docker-compose

# Test
sudo docker run hello-world

If docker-compose does not work after installation and you get this error message Couldn't connect to Docker daemon at http+unix://var/run/docker.sock or something similar, add yourself to the docker group, logout and login:

  • usermod -aG docker ${USER}
