Emacs "No route to host" :name "elpa.gnu.org" - emacs

I just started getting this when I start up my Emacs (at command line with emacs --debug-init):
Lisp error: (file-error "make client process failed" "No route to host" :name "elpa.gnu.org" :buffer #<killed buffer> :host "elpa.gnu.org" :service 80 :nowait nil :tls-parameters nil)
signal(file-error ("make client process failed" "No route to host" :name "elpa.gnu.org" :buffer #<killed buffer> :host "elpa.gnu.org" :service 80 :nowait nil :tls-parameters nil))
package--download-one-archive(("gnu" . "http://elpa.gnu.org/packages/") "archive-contents" nil)
A restart with emacs --insecure and just emacs however seems to work. BTW, I've got everything setting up with use-package with :ensure t set. The good restarts, however, produce this in *Messages* when I do a M-x list-packages but then skip over and finish just fine:
error in process sentinel: Error retrieving: http://elpa.gnu.org/packages/archive-contents (error connection-failed "failed with code 113
" :host "elpa.gnu.org" :service 80)
I googled and saw various init setup tinkering solutions ... which I don't believe apply to this particular issue. I'm guessing there's something wrong "out there", not on my machine. Any ideas/suggestions? I'm on latest Ubuntu and Emacs 26.2.

M1 mac error: Emacs error "Failed to initialize color list unarchiver" when I call it in the terminal, why does it happen and how to fix?

I saw this question Emacs error "Failed to initialize color list unarchiver" when I call it in the terminal but it didn't help. I get the similar error but for m1 chip instead of intel x86 I think:
2022-04-14 17:08:00.370 Emacs-arm64-12[24779:1101019] Failed to initialize color list unarchiver: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: non-keyed archive cannot be decoded by NSKeyedUnarchiver" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: non-keyed archive cannot be decoded by NSKeyedUnarchiver}
I added the command I was told to my .emacs but it didn't help:
(meta_learning) brandomiranda~/coq4brando/cs598 ❯ cat ~/.emacs
;; Open .v files with Proof General's Coq mode
(load "~/.emacs.d/lisp/PG/generic/proof-site")

(evil-mode 1)
(load-file (let ((coding-system-for-read 'utf-8))
(shell-command-to-string "agda-mode locate")))
(delete-file "~/Library/Colors/Emacs.clr")
why is this error happening and how do I remove it?

Emacs failed to load initialization file

I am using Emacs 25.3 under windows 10 platform.
It works fine until one time I started it and got the following message:
Warning (initialization): An error occurred while loading ‘
c:/Users/shore/AppData/Roaming/.emacs’:
Wrong type argument: listp, <html>
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.
As instructed I used --debug-init option to start and got the following message:
Debugger entered--Lisp error: (wrong-type-argument listp <html>)

Can anyone tell me where my problem is and how to fix it?
It's telling you that when it tried to read file archives/gnu/archive-contents it expected to read Lisp (more specifically a Lisp list). Instead, it encountered <html> (presumably text in the file).
A guess is that you somehow downloaded or picked up an HTML file (perhaps one that describes the archive file or that has links to download it) instead of downloading or picking up a file of Lisp code. Try once again to obtain that archive file.

emacs crashed after executing list-packages and cannot recover

My emacs crashed after I innocently entered the list-packages command and it will not recover.
I have tried re-installing it from homebrew, all I have in the *messages* buffer is this message:
Loading /usr/local/share/emacs/site-lisp/proof-general/generic/proof-site.el (source)...done
package-read-archive-contents: Wrong type argument: arrayp, (spass . [(1 1 2) nil "Emacs wrapper for DisPass" single])
What can I do?

slime doesn't work in emacs24

I use emacs24 in archlinux.If i use the slime packages from marmalade.org,then when i use M-x slime the error is:
debugger invoked on a SB-INT:SIMPLE-FILE-ERROR in thread
#<THREAD "initial thread" RUNNING {AB007A9}>:
Couldn't load
"/home/sinners/.emacs.d/elpa/slime-20100404.1/swank-loader.lisp": file does
not exist.
Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Exit debugger, returning to top level.
but if i use the slime-cvs packages from the offical site,the error is:
Debugger entered: (("Error in timer" slime-attempt-connection (#<process inferior-lisp> nil 2) (void-variable --cl-accu--)))

anyone can help me?
Problem with --cl-accu-- variable signs about breakage of emacs cl package in presence of lexical scoping. Try to go to slime.el in your slime distribution, find string
;; lexical-binding: t in the ;; Local Variables: section at the end of the file and change it to ;; lexical-binding: nil. And remove old slime.elc file if you have one.
I had the exact same problem, which was solved by deleting the slime.elc file, that I had compiled earlier using byte-recompile-directory. I didn't try compiling it again.
I'm not sure, but this problem can be due to different versions of SLIME and SWANK. However you should just use pacman to install a lisp implementation ­(I think that SBCL is the most popular implementation on Linux) and then use quicklisp to install everything else.
See this blog post to see how to install SWANK and SLIME with quicklisp.
