Emacs 26.1 as packaged in Debian buster.

After doing M-x package-list-packages I can select any package from the MELPA repo https://melpa.org/packages/ and then install it. But when I try to get any package from the GNU ELPA repo https://elpa.gnu.org/packages/ I get an error:

Contacting host: elpa.gnu.org:443
package-install-from-archive: https://elpa.gnu.org/packages/ack-1.8.tar: Bad Request

And of course I get the same error if I try to install it directly, outside the package menu with M-x package-install <RET> ack.

When I browse elpa.gnu.org with Firefox I can download the file just fine, and I can also download it directly from the command line with

curl -L -O https://elpa.gnu.org/packages/ack-1.8.tar

What gives?

Update: I found https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=942413 . But I checked and I already have the latest signing key in ~/.emacs.d/elpa/gnupg , namely 066DAFCB81E42C40. So my problem must be different.

It might be this bug: https://debbugs.gnu.org/34341. It's fixed in Emacs 26.3+ and the workaround is:

(setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")

  • Thanks. Somehow I don't want to mess with TLS protocol settings, though :-( I reported this to Debian, if it turns out you were right I'll ACK. – q.undertow May 13 at 5:21
