Hi list,
is ELPA working for everyone?
I was trying to record a screencast about Emacs and I decided to
create a new user with no rcfiles, and run everything from his
account. I then ran "emacs" to invoke the default Emacs here - this is
a Debian Stable, and M-x emacs-version says this:
GNU Emacs 26.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version
3.24.5) of 2019-09-23, modified by Debian
Then I tried M-x list-packages. It did not list anything from ELPA,
and gave this error:
error in process sentinel: Error retrieving:
https://elpa.gnu.org/packages/archive-contents "incomprehensible
buffer"
I installed gnu-elpa-keyring-update and tried M-x list-packages again;
same error. I started emacs again and ran M-x list-packages again:
same thing.
I would love to know how to debug the functions in package.el but I
don't. Please send sexps! =\
Btw, the file
/home/eduardo/.emacs.d/elpa/archives/gnu/archive-contents/.signed
contains this, but in a single line:
Good signature from 066DAFCB81E42C40 GNU ELPA Signing Agent (2019)
<elpasign@elpa.gnu.org> (trust undefined) created at
2020-04-26T22:05:02+0100 using RSA
and I've uploaded the contents of
/home/eduardo/.emacs.d/elpa/archives/gnu/archive-contents
to:
https://0x0.st/ieQc.txt
I also tried to run slight variants of the tests above with an emacs26
compiled from the git repo with:
git checkout emacs-26.3
./autogen.sh
./configure
make
and it also couldn't access ELPA if I ran it from my test user.
When I ran emacses using my default user ("edrx") and loading my
(HUUUGE) ~/.emacs file they didn't have any problems accesing ELPA and
MELPA, but I didn't perform many tests with them to discover what code
in my ~/.emacs was, huh, how do I say?, "fixing the bug".
Thanks in advance =/,

Does 26.3 still fail if you start from a fresh .emacs.d/ directory? I
think there were some encoding related fixes made in package.el for
26.3, but they may not help with existing mis-encoded files.

Hi, sorry for the delay...
Long story short: the Emacs that comes in Debian Stable - 26.1 -
cannot access ELPA when we run `M-x list-packages', and:
1) this MAY BE due to a quirk in
<https://elpa.gnu.org/packages/archive-contents>,
2) I can't find a workaround that I can recommend to beginners.
I'll write about 26.3 in another message.
Now: long story long. I rewrote my tests in a format - using eev-isms
- that lets me re-execute them again very quickly without or with
modifications. Here are the commands; note that I am running them in
Debian Stable (a.k.a. "Buster").
su - eduardo
<p455w0rd>
rm -Rfv .emacs*
rm -Rfv .gnupg
ls -lAF
emacs --version
apt-cache show emacs
# Version: 1:26.1+1-3.2+deb10u1
# See also: https://packages.debian.org/buster/emacs
cat > o <<'%%%'
(list-packages)
(setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")
(list-packages)
%%%
emacs -nw o
M-x list-packages
If I run `M-x list-packages' - or if I type C-e C-x C-e in the first
line - it does not list anything from ELPA and gives this error:
error in process sentinel: Error retrieving:
https://elpa.gnu.org/packages/archive-contents "incomprehensible
buffer"
If I then run the (setq ...) above, as suggested here,
https://www.reddit.com/r/emacs/comments/cdf48c/failed_to_download_gnu_archive/
nothing changes, in the sense that if I then execute the
`(list-packages)' in the third line with C-e C-x C-e I still don't get
anything from ELPA, and I get the error "incomprehensible buffer".
I was working on the script of a screencast that would start with
instructions for installing a package from ELPA, but I am quite
embarassed by this bug... so I interrupted everything to discuss the
bug.
Is anyone else here able to reproduce it? Are there any easy fixes?
Are there any easy fixes that you would recommend to beginners who
happen to be using Debian Stable? Compiling a more recent Emacs from
git is not an "easy fix"...
Cheers,
Eduardo Ochs

Oh, sorry, I somehow didn't realize you meant the "incomprehensible
buffer" part literally until now. Try doing
(setq debug-on-signal t debug-on-error t)
before calling list-packages to stop at the error in the debugger (it's
possible you could hit some different errors first, in which case press
'c' to continue until you get the "incomprehensible buffer" one again).
Then check the contents of the buffer. You can get the buffer name to
look at, with
e (current-buffer) RET
in the debugger. The name will probably be " *temp*" (note the leading
space) possibly with a random number as suffix. Then look at the
contents, hopefully that will give a clue as to what happened.

(That was 17 weeks ago.)
Did you ever find out anything more about what could cause this?

More information was requested two months ago, but was not given, so
I'm closing this bug report. If further progress can be made here,
please respond to the debbugs address and we'll reopen.
