I have a lua plugins script defining local fn = vim.fn. A couple of lines later it defines local install_path = fn.stdpath('data'). This script is called from my init.vim by lua require('plugins').

Whenever I start nvim, I get the error message: Error while calling lua chunk: /home/MYUSERNAME/.config/nvim/lua/plugins.lua: attempt to index local 'fn' (a nil value),

So I figure, vim.fn is nil. I guess something with my setup is wrong, but I don't know what and I don't know how to debug this. The only idea I had was running :checkhealth. It gave me no errors:

health#nvim#check

I also tried un- and reinstalling neovim already

$ sudo apt remove neovim
$ sudo apt install neovim

My machine is running on Ubuntu 20.04 LTS.

What could be the source of this bug, how can I debug and fix this?

I had similar issue with my Ubuntu 20.04 running on WSL2.

After type nvim -v, found out sudo apt install neovim can only install older version, not sure why.

Follow this link to install a latest versioni, https://github.com/neovim/neovim/wiki/Installing-Neovim#ubuntu. I installed stable version 0.7.2, but i guess latest pre-release version will do also.

    "sudo apt install neovim can only install older version, not sure why." It's because the official apt repository does not host up-to-date neovim binary. The link you provided adds a third-party repository, where maintainers keep the neovim binary updated. – 3N4N Oct 26 '22 at 12:28

    Welcome to [vi.se]! This answer would strongly benefit from putting the actionable answer ("install the latest version by doing X, Y, Z") and from some formatting (which is Markdown). Consider an [edit] to improve the post. – D. Ben Knoble Oct 26 '22 at 20:47
