Host key verification failed

[mikwee]

• nvim --version:

NVIM v0.8.3
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3
Compiled by runneradmin@fv-az171-224

Features: -acl +iconv +tui
See ":help feature-compile"

   system vimrc file: "$VIM\sysinit.vim"
  fall-back for $VIM: "C:/Program Files (x86)/nvim/share/nvim"

Run :checkhealth for more info

• git --version: git version 2.24.1.windows.2
• Operating system/version: W10
• Terminal name/version: Neovide

Steps to reproduce

1. Add use 'nvim-treesitter/treesitter' to plugins.lua
2. Restart Neovim
3. Use :PackerSync
4. Get the following error for treesitter: fatal: could not read Username for 'https://github.com': terminal prompts disabled
5. Follow these tutorials to generate an SSH key and put it in GitHub, then type git config --global url.ssh://git@github.com/.insteadOf https://github.com/ into Git Bash (So basically, follow terminal prompts disabled #748)
6. Restart Neovim
7. Use :PackerSync

Actual behaviour

Got the following error for all plugins:

Cloning into 'C:\Users\mikwee\AppData\Local\nvim-data\site\pack\packer\start\[NAME OF PACKAGE]'...
    Host key verification failed.
    fatal: Could not read from remote repository.
    Please make sure you have the correct access rights
    and the repository exists.

Expected behaviour

I expect Packer to install all specified packages correctly.

packer files

Plugin specification file(s)

You mean plugins.lua? Here it is:

local ensure_packer = function()
  local fn = vim.fn
  local install_path = fn.stdpath('data')..'/site/pack/packer/start/packer.nvim'
  if fn.empty(fn.glob(install_path)) > 0 then
    fn.system({'git', 'clone', '--depth', '1', 'https://github.com/wbthomason/packer.nvim', install_path})
    vim.cmd [[packadd packer.nvim]]
    return true
  end
  return false
end

local packer_bootstrap = ensure_packer()

return require('packer').startup(function(use)
  use 'wbthomason/packer.nvim'
  use 'ellisonleao/gruvbox.nvim'
  use 'nvim-tree/nvim-tree.lua'
  use 'nvim-tree/nvim-web-devicons'
  use 'nvim-lualine/lualine.nvim'
  use 'nvim-treesitter/treesitter'
  use {
	'nvim-telescope/telescope.nvim',
	tag = '0.1.0',
	requires = { {'nvim-lua/plenary.nvim'} }
  }


  -- Automatically set up your configuration after cloning packer.nvim
  -- Put this at the end after all plugins
  if packer_bootstrap then
    require('packer').sync()
  end
end)

Host key verification failed is an ssh issue, not a packer issue. You can verify this by trying to git clone the package yourself.

This happens when the fingerprint of the host changes.
This must not happen for github. This usually means someone's doing an MITM attack.

I don't know how to debug this on windows. On Linux the host keys are stored in ~/.ssh/known_hosts.
The first time you connect to a host, it's key gets stored here. If someone tries to MITM you, ssh will be able to detect this and it will say that the key is different from the one that we first encountered.

I've since removed my key from GitHub, and this issue keeps happening only with Packer.
