This report mirrors the issue I submitted to Spacemacs as issue 13866. This
issue
has not received any replies yet. Since then I reproduced the issue with
'emacs -Q'

Link to Spacemacs issue (with diagnostic and traceback info)
- https://github.com/syl20bnr/spacemacs/issues/13866

I run Emacs on MSYS2. On August 20, 2020, I refreshed MSYS2 packages
and Emacs 27.1 was installed.

This problem is generated with 'emacs -Q --debug-init':
- no traceback info generated despite '--debug-init'
- When Emacs comes up, execute command: 'package-list'
- The package list comes up (it has 478 packages)
- The *Error* buffer comes up with the following contents:

Failed to verify signature archive-contents.sig:

Command output:

gpg: Can't check signature: No public key

The offending file path consists of the current directory, followed by
c:/Users/977315/.emacs.d/elpa/...
I verified this by launching emacs from a different directory. That change
would be reflected in the filepath, for example, when launched from the
~/tmp directory:

I don't understand why this path is used.  It should be using:

    (expand-file-name "gnupg" package-user-dir)

What is the value of `package-gnupghome-dir' and `package-user-dir' on
your machine?

Well, I'm stomped.  But I don't know much of anything about Windows.

Does anyone have an idea why a path like this would be used on Windows?

  "/c/Users/977315/tmp/c:/Users/977315/.emacs.d/elpa/gnupg/pubring.kbx"

Yes, it happens when MSYS2 ports of programs (gpg?) are mixed with
native Windows ports.

Should we do anything about that, or is it expected?

My guess is it's not an Emacs problem.  But to be sure, I miss some
details:

  . is gpg being used an MSYS2 port of a native Windows
    (a.k.a. "mingw") port?
  . was the problematic file name emitted by gpg, or was it generated
    by Emacs and passed to gpg?

The last question could be answered by stepping in Edebug through
package--check-signature-content and epg functions it calls, and
looking at the file names we place on the gpg command line.

If the OP could provide this information, we could easily see whether
there's some problem in Emacs in this use case.

Tracing package--check-signature-content

   - I trace it in plain emacs, started with emacs -Q
   - I edebug the function and step through it
   - I have a single signature and its status is no-pub-key which triggers
   the No public key error
      - This results in the message in the error buffer with the malformed
      directory

Below is the code annotated with values of key variables. I did not see
anything obvious.

I evaluated context at several points. I following deeper into the epg-...
functions, stopped when I saw compiler macros. I would need guidance to
trace those.

Let me know if you required additional debug/testing, including issuing gpg
commands in the shell.

(defun package--check-signature-content (content string &optional sig-file)

Thanks.  I think the situation is clear:

The "C:/msys64-a" part indicates that gpg.exe is an MSYS2 port, not a
native MinGW port.  So it's expected that it will manipulate
Posix-like file names like /c/foo/bar and /home/977315/...  It is also
expected that it may not realize that "c:/foo/bar" is an absolute file
name, since in the Posix world any file name which doesn't begin with
a slash is not an absolute file name.  So it concatenates the file
name passed to it by Emacs with /home/977315/... on the assumption
that the file name passed by Emacs is a relative file name.

Bottom line: you need to install a native MinGW port of gpg, or make
some wrapper script for gpg which would convert Windows d:/foo/bar
file names into the Posix-like format expected by MSYS2 executables.

Thanks.

I think this solved it:

   1. Installed MinGW version: pacman -S mingw64/mingw-w64-x86_64-gnupg
   2. Started emacs -Q in the MingGW64 terminal (not the MSYS2 terminal)
   3. package-list-packages completes without errors:

From the *Messages* buffer:

Importing package-keyring.gpg...done
Setting ‘package-selected-packages’ temporarily since "emacs -q" would
overwrite customizations
Package refresh done
Packages that can be upgraded: 2; type ‘U’ to mark for upgrading.

To me this implies that gnupg should be installed along with Emacs 27.1 in
MinGW64. I will try to contact the maintainer to suggest that.

Thank you very much for your help.

Mirko

Yes, using MSYS2 ports of programs with the MinGW Emacs is prone to
subtle hard-to-debug errors.  MinGW ports should be preferred.

You are welcome.  I'm therefore closing this bug report.
