Server "lua_ls" is not a valid entry in ensure_installed.

[githubxone]

I get below warning when I open neovim:

[mason.nvim] [mason-lspconfig.nvim] Server "lua_ls" is not a valid entry in ensure_installed. Make sure to only provide lspconfig server names. 

and this is my config:

return {
  "neovim/nvim-lspconfig",
  dependencies = {
        "williamboman/mason.nvim",
        "williamboman/mason-lspconfig",
  },

  config = function()
    local servers = {
      "lua_ls",  -- lua
      "clangd",  -- c cpp
      "pylsp",   -- python
    }

    local capabilities = require('cmp_nvim_lsp').default_capabilities()
    require("mason").setup({
      ui = {
        icons = {
          package_installed = "√",
          package_pending = "→",
          package_uninstalled = "×"
        }
      }
    })
    require("mason-lspconfig").setup({
      ensure_installed = servers,
    })
    require("lspconfig").lua_ls.setup {
      capabilities = capabilities,
    }
    require("lspconfig").clangd.setup {
      capabilities = capabilities,
    }
    require("lspconfig").pylsp.setup {
      capabilities = capabilities,
    }
  end
}

I have the same issue.

I also tried intelephense, to confirm that the issue isn't specific to the Lua language server, and encountered the same error.

@githubxone @monooso I have the same issue after trying multiple, valid entries. After a little digging, I note that Mason cannot install/update the registry with a Github API error. Is this the same for yourselves or do I need to raise a separate issue?

FYI I resolved my issue by installing curl on my system, as it was missing. Went through the results of checkhealth mason. Give that a go; hope to have been of some help!
