Dear Maintainers,

while testing gpg-from-sq I noticed that I get an incorrect behaviour
trying to retrieve a key from a keyserver and exporting it as
upstream/signing-key.asc.

I have a script that does something like :

rm ~/addkey.keyring
gpg --no-default-keyring --keyring ~/addkey.keyring --keyserver hkp://keyserver.ubuntu.com --recv-keys F1955ED9D1C2D10D80B31B3B14EE37CD15C53BDD
gpg --yes --no-default-keyring --keyring ~/addkey.keyring --export --export-options export-minimal,export-clean --armor --output debian/upstream/signing-key.asc


1. This breaks with gpg-from-sq which tells me
gpg:   error: Key resource "/home/coucouf/addkey.keyring" does not exist


2. If I touch ~/addkey.keyring first then the steps above will run without errorring out, but the resulting ascii key is incorrect.
Running uscan --download-current-version afterwards tells me:

uscan die: Failed to dearmor key(s) from debian/upstream/signing-key.asc at /usr/share/perl5/Devscripts/Uscan/Output.pm line 77.


You’ll find the keys exported by gpg and sq in attachment.
This examples comes from skrooge master or debian/2.33.0-1 tag. [1]

Thanks for your work on the sequoia stack.

I tried to reproduce this on my sid system, and there gpg-sq didn't
manage to download the key at all:

capitol@tone3:/tmp$ rm addkey*
capitol@tone3:/tmp$ touch addkey2.keyring
capitol@tone3:/tmp$ LANG=C gpg --no-default-keyring --keyring

.rw-rw-r-- capitol capitol   0 B Sat Jan 11 10:42:01 2025  addkey2.keyring

Still looks like a bug to me.
