I'm trying to configuring Emacs on Windows and there is one package "use-package" which I wanna to insert in this on my configuration, but when I press to execute on Emacs show the message "Symbol's function definition is void: use-package"
(setq inhibit-startup-message t)
(require 'package)
(setq package-enable-at-startup nil)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/"))
(add-to-list 'package-archives '("gnu" . "https://elpa.gnu.org/packages/"))
(package-initialize)
(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))
Sometimes I receive error message "use-package is unavailable."
Debugger entered--Lisp error: (void-function package-installed-p)
(package-installed-p (quote use-package))
(if (package-installed-p (quote use-package)) nil (package-refresh-contents) (package-install (quote use-package)))
eval((if (package-installed-p (quote use-package)) nil (package-refresh-contents) (package-install (quote use-package))) nil)

You should be able to find use-package in the list produced with M-x package-list-packages. If that is the case, then (package-install 'use-package) should succeed: the package is available on MELPA.
To use it, you have to add
(require 'use-package)
to your .emacs (or equivalent).

I have Emacs running in WSL2

About couple of weeks ago open buffers started getting scroll-lock-mode enabled. I have it set to nil by default. Moreover, if I disable scroll-lock-mode after some time it gets enabled. I don't have anything anywhere in the configuration related to scrolling. I have instrumented scroll-lock-mode function, but when it jumps in it, seems to be called from random spots
(let ((last-message (current-message))) (setq scroll-lock-mode (cond ((eq arg 'toggle) (not scroll-lock-mode)) ((and (numberp arg) (< arg 1)) nil) (t t))) (when (boundp 'local-minor-modes) (setq local-minor-modes (delq 'scroll-lock-mode local-minor-modes)) (when scroll-lock-mode (push 'scroll-lock-mode local-minor-modes))) (if scroll-lock-mode (progn (setq scroll-lock-preserve-screen-pos-save scroll-preserve-screen-position) (setq-local scroll-preserve-screen-position 'always)) (setq scroll-preserve-screen-position scroll-lock-preserve-screen-pos-save)) (run-hooks 'scroll-lock-mode-hook (if scroll-lock-mode 'scroll-lock-mode-on-hook 'scroll-lock-mode-off-hook)) (if (called-interactively-p 'any) (progn nil (unless (and (current-message) (not (equal last-message (current-message)))) (let ((local " in current buffer")) (message "Scroll-Lock mode %sabled%s" (if scroll-lock-mode "en" "dis") local))))))

Scroll-Lock mode enabled in current buffer
How to I make it disabled for good ? I used (setq-default scroll-lock-mode nil) but it is still being enabled by something.
disabling Scroll_lock ends the behavior
(define-key global-map (kbd "<Scroll_Lock>") nil)
linking the key back to scroll-lock-mode will let this problem re-emerge.
I haven't really figured out what's behind such erroneous auto trigger of scroll-lock-mode though.
In the (amateurish, convoluted) code below, I am trying create an environment where there may be multiple serial-term buffers/windows at the same time. I am doing everything I can think of (and just random desperate things) to make the variables local to the buffer running the terminal to which they pertain. For instance, there may be a buffer "serial-1a2b-buffer" with the terminal "serial-1a2b-term" running in it while at the same time there's a buffer "serial-3c4d-buffer" with the terminal "serial-3crd-term" running in it.
I can get the buffers/terminals setup and running with defun setupserial, but defun killserial and defun resetserial don't get the right value for "termname" and "buffname". It might be the values in the other buffer or it may be past values for buffers and terminals that no longer exist.
(In case anyone is wondering, I do a lot of work with microcontrollers. If the serial connection to them is interrupted, like with a hardware reset, then the serial process dies. The idea was to have a quick way to reset the connection - like with a function bound to a key sequence.)
(defvar serialspeed "115200")
(defvar serialport "/dev/ttyACM0")
(defvar serialbasename "serial")
(require 'term)
(defun setupserial (serialport serialspeed)
(interactive

Your problems are sequential. Having created all of your buffer-local variables, you are then destroying them all by calling a new major mode.
The section on "Derived modes, and mode hooks" in this answer might be useful reading, but the key point is that the first thing that happens when you call a major mode is kill-all-local-variables.
Because you are setting global values too, in the absence of local values your other commands will end up using whatever the most-recent global value happened to be.
Set the major mode first.
What I'm trying to accomplish
I'd like to use go-mode/lsp-mode together. I struggle to get lsp-mode to even execute at first, finally got it to work by appending the paths :facepalm:.
The issue
The issue now is that when lsp-mode starts up for the working golang directory, I receive this error:
LSP :: Error from the Language Server: no views in the session (Unknown error) [3 times]
I've searched around the internet for answers, but have yet to find anything that is relevant to my problem. I'm reaching out to the community for some guidance.

I've had this happen when the go environment is not correct.
As a diagnostic try commenting out the go* exec-paths from your lsp-mode.el and set appropriate environment variables (GOROOT, GOPATH and GO111MODULE if you're using it), including adding $GOROOT/bin and $GOPATH/bin to PATH.
Also if still not working verify within emacs those environment variables are set correctly.
For linux of course you can export all that and run emacs from the terminal to test.
Sorry if this is a silly question; I am a complete novice when it comes to emacs.
Recently, I began to do research on how to set up emacs and stumbled upon a great video series by Mike Zamansky. However, whilst following this video (creating an org init file), all of the packages I installed onto my emacsclient proceeded to not work. During initialization, there was an error - namely, "Symbol's value as variable is void: Removes." I copied his tutorial verbatim and I don't see any potential syntactical errors - perhaps I overlooked some errors. However, I've been searching throughout the internet, but could not find any answers to this problem.
Here is the contents of the init.el file:
(require 'package)
(setq package-enable-at-startup nil)
(add-to-list 'package-archives
'("melpa" . "http://melpa.org/packages/"))
(package-initialize)

(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))
(org-babel-load-file (expand-file-name "~/.emacs.d/myinit.org"))
Here is the error:
Warning (initialization): An error occurred while loading
‘/Users/Kyojin/.emacs.d/init.el’:

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace.

Search for the word Removes in your init file, "/Users/Kyojin/.emacs.d/myinit.el" (or possibly in some file that it loads).
If you don't find it immediately then recursively bisect your init file to find the code that is problematic. You can do that by commenting out first 1/2, then 3/4, then 7/8,... of the file until you locate the problem. You can comment a block of text/code by selecting it and then using M-x comment-region. You can uncomment a selection the same way, but with C-u first: C-u M-x comment-region.
I am unable to access remote files in my usual way:
C-x C-f
[server]:[path][file]
and am thrown this error:
Wrong Type Argument: listp, [[server]:[path][file]
I'm not even sure how to debug this further.
any help is appreciated.

Check what command C-x C-f is bound to (use C-h k). Is it the standard binding find-file? (It doesn't sound like it.)
If not, check its interactive spec. The command is expecting to receive a list as argument, and it is instead receiving (what looks like) a string.
This is the interactive spec of find-file:
(interactive
(find-file-read-args "Find file: " (confirm-nonexistent-file-or-buffer)))
If the interactive spec of your C-x C-f command, like this one, has a non-string as its argument, then you can either M-x debug-on-entry THE-FUNCTION, where THE-FUNCTION is the function called for the argument (find-file-read-args, in the case of find-file), or wrap that argument so that the debugger is invoked:
(progn (debug) (WHATEVER-WAS-THERE-BEFORE))
Either way, the debugger will open for the interactive part of reading the file name, and you can walk through the debugger to see what goes wrong.
But probably you can figure out the problem just by inspecting the code -- the interactive spec. The argument to your command (whatever it is) is expected to be a list, but it is a string.
I would start by seeing what happens with a local file name. Do you get an error for that too?
Another thing I notice is that the error reports an extra [, in front of what you say you typed as input. That should provide a clue too. What you think it is reading is not what it has read.
