can't get lsp-mode installed, and all the relevant issues are years
old

I was trying to follow https://ianyepan.github.io/posts/emacs-ide/ to
get `lsp-mode` configured for Python, but I got stuck at the very
beginning, trying to get lsp-mode installed.

GNU Emacs 27.2
MacOS Monterey

Here's what I've tried since `use-package` failed.

- `package-refresh-contents`
- `package-install <RET> lsp-mode` -- this fails.

`package-compute-transaction: Package ‘spinner-1.7.3’ is unavailable`

    package-archives is a variable defined in ‘package.el’.
    Its value is
    (("melpa" . "https://melpa.org/packages/")
     ("org" . "https://orgmode.org/elpa/"))


I've confirmed that both lsp-mode and lsp-pyright exist on Melpa
unstable. Package-refresh-contents works fine. I just keep getting the
same message about spinner-1.7.3 not being available. I can't even
think how I would debug this further. :(

Seems that spinner is on elpa
https://elpa.gnu.org/packages/spinner.html

So add elpa to your package archives

yes, that fixes it, thank you! I've had emacs configured for...
several years without connecting to ELPA, and I had no idea that would
cause problems. Very strange, and I really appreciate the help!

Note that there are now (starting from Emacs 28) *two* standard
package archives defined:

    (("gnu" . "https://elpa.gnu.org/packages/")
     ("nongnu" . "https://elpa.nongnu.org/nongnu/"))

Things in the (fairly new) Non-GNU ELPA are likely to also be found in
MELPA, so if you use the latter you *probably* don't need the former;
but you certainly don't want to remove GNU ELPA from the list -- the
packages in there are highly likely to not be in any other package
archive.

See https://melpa.org/#/getting-started

Using `add-too-list` to configure `package-archives` is a good idea,
especially going forward. Some emacs core packages are now updated in
GNU ELPA more often than the Emacs release cycle.
