Can I use Homebrew on Ubuntu?

As of February 2018, installing brew on Ubuntu (mine is 17.10) machine is as simple as:

sudo apt install linuxbrew-wrapper

Then, on first brew execution (just type brew --help) you will be asked for two installation options:

me@computer:~/$ brew --help
==> Select the Linuxbrew installation directory
- Enter your password to install to /home/linuxbrew/.linuxbrew (recommended)
- Press Control-D to install to /home/me/.linuxbrew
- Press Control-C to cancel installation
[sudo] password for me:

For recommended option type your password (if your current user is in sudo group), or, if you prefer installing all the dependencies in your own home folder, hit Ctrl+D. Enjoy.

I just tried installing it using the ruby command but somehow the dependencies are not resolved hence brew does not completely install. But, try installing by cloning:

git clone https://github.com/Homebrew/linuxbrew.git ~/.linuxbrew

and then add the following to your .bash_profile:

export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"

It should work..
