I’m using Ubuntu for my development environment, and Ubuntu does not have the latest Neovim in their repository.
That’s why I choose to install the last version by source. The steps I take are:
wget https://github.com/neovim/neovim/releases/download/v0.9.1/nvim-linux64.tar.gz
tar xfz nvim-linux64.tar.gz
sudo mv nvim-linux64 /opt/nvim
Now you have to make sure that /opt/nvim/bin is part of your path. If you are
smart, and using the Fish shell, add this to your Fish config.
fish_add_path -aP /opt/nvim/bin
If you are on Bash:
export PATH=/opt/nvim/bin:$PATH
Enjoy your latest version of Neovim!
