Assuming an Ubuntu image...

1. sudo apt update && sudo apt install make gcc perl
2. Install Guest Additions
3. sudo apt install -y git vim-gtk3 curl python3-pip
4. sudo snap install code --classic
5. Install powerline fonts source:

• Linux bash:

# clone
git clone https://github.com/powerline/fonts.git --depth=1
# install
cd fonts
./install.sh
# clean-up a bit
cd ..
rm -rf fonts

• WSL Bash: Follow instructions here

• Next, set the terminal preferences to a * for Powerline font (Terminal -> Hamburger Menu -> Profiles (Current Profile) -> Custom Font). Currently I like Go Mono for Powerline Regular.

6. Get oh-my-bash:
   • bash -c "$(curl -fsSL https://raw.githubusercontent.com/ohmybash/oh-my-bash/master/tools/install.sh)"
   • Adjust settings appropriately
7. Install nvm
   • curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
   • Install the latest node/npm lts: nvm install --lts
8. git clone git@github.com:pmcneely/dotfiles.git
   • Adjust theme and aliases as appropriate
9. Turn Settings -> Privacy -> Screen Lock to "Off"
10. Install python virtualenvwrapper (could be the only sudo pip command ever needed!)
    • See source
    • sudo pip install virtualenvwrapper
11. Update oh-my-bash aliases, dotfiles settings, and bash fragments (from dotfiles) as appropriate
12. Configure vim:
    • Install vundle
      • git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
      • ln -s dotfiles/vimrc .vimrc
      • vim .
      • :PluginInstall
    • Install and configure youcompleteme
      • Install required headers and programs: sudo apt install -y exuberant-ctags cmake
      • Install support for other languages: sudo apt install -y mono-complete golang default-jdk

$ cd ~/.vim/bundle/youcompleteme
$ python3 install.py --all

13. On the host machine, run:

# See if vboxusers already exists
$ getent group | grep vboxusers
# If not, add the group
$ sudo groupadd vboxusers
# Allow hardware access to e.g. USB media
$ sudo usermod -aG vboxusers $USER

14. In the Guest machine, run:

$ sudo usermod -aG vboxsf $USER

14.1 If running Docker:

sudo usermod -aG docker $USER

(These commands allow the virtual machine to mount e.g. USB 3.0 devices and shared folders with the host) see here 15. ...profit?
