Copilot plugin fails to load for me, Lazy.nvim clone stucks on 100% Resolving Deltas or manual install not detected

[Mono404Fun]

I’m trying to use GitHub Copilot with Neovim, but the plugin fails to load reliably. Whether I use the Lua version (via copilot.lua) or Vim‑script version (via copilot.vim), I hit different issues: Lazy.nvim clone gets stuck when it reaches 100% Resolving deltas until I get a timeout error, even when I tried manual installation, Neovim (Lazy.nvim) fails to register/detect the plugin, so commands don’t exist. All my other plugins work fine BTW (themes, bufferline, lualine...etc).

🧪 Environment

• OS: Linux (MX Linux XFCE 25)
• Neovim version: v0.11.5
• Node.js version: v18.20.4 (≥ 16 required for Copilot)
• Plugin manager: Lazy.nvim
• Other plugins: (examples) lualine.nvim, bufferline.nvim, nvim-treesitter, toggleterm.nvim, nvim-notify, nord.nvim, etc. — all load fine

What I tried & What happens

✅ Using copilot.lua (Lua version via Lazy.nvim)

I added this plugin to my Lazy.nvim config with default setup. On Neovim startup, Lazy.nvim tries to clone the plugin: progress reaches “100% resolving deltas”. After that, clone hangs indefinitely, eventually failing with a timeout error. I retried multiple times (network stable, Git config adjusted, buffer size increased) — same problem persists.

✅ Using copilot.vim (Vim‑script version via Lazy.nvim)

I replaced with the Vim‑script version and attempted install via Lazy.nvim. The same behavior: cloning hangs and times out. All other plugins via Lazy.nvim install normally (themes, tools, utilities).

✅ Manual clone of copilot.vim

I ran:

git clone --depth=1 https://github.com/github/copilot.vim.git \
  ~/.config/nvim/pack/github/start/copilot.vim

• Clone completes successfully.
• Folder structure is correct (plugin/, autoload/, lua/, doc/, syntax/, etc.).
• Restarting Neovim: plugin does not load — :Copilot commands do not exist.
• :scriptnames shows no copilot.vim/plugin load.

✅ What I verified

• :echo &runtimepath — the cloned path does not appear.
• Tried vim.cmd [[packadd copilot.vim]] in init.lua → still no commands.
• Verified Node.js version (v18.20.4) and Neovim version (v0.11.5).

🎯 What I expect / What should happen

• Copilot should load properly in Neovim.
• :Copilot commands should be available.
• Lazy.nvim should install and load it without hanging.
• Manual installation should register the plugin properly if path is correct.

❓ Questions / Issues I need help with

1. Why does Lazy.nvim hang / timeout when cloning Copilot, while other plugins install fine?
2. Why does manual clone not get recognized by Neovim — the pack/start directory seems correct but plugin isn’t loaded.
3. Is there a known compatibility issue between Copilot (either version) and my environment?
4. Are there recommended steps to install Copilot manually (or via Lazy.nvim) to avoid hanging / detection issues?
5. If both official versions consistently fail, is there a known alternative or fork that works reliably?

✅ What I’ve ruled out

• Network instability / Git config -> I successfully cloned other repos.
• Wrong folder path -> folder structure is correct.
• Other plugin conflicts -> other plugins load and work normally.
• Node.js / Neovim versions -> meet minimum requirements.
