[pkg-gnupg-maint] Bug#1108406: gnupg: On Debian 13, fail to import a secret key exported from a Debian 12 host

[Frédéric Boiteux]

Package: gnupg
Version: 2.4.7-21
Severity: important
X-Debbugs-Cc: fboiteux at free.fr

Dear Maintainer,

I want to use my GnuPG key on a new laptop with Debian 13. I’ve exported my
key from my old computer using :

gpg --export-secret-keys --export-options backup --armor --output cleComplete.gpg.asc fredmob at free.fr

and copied that file cleComplete.gpg.asc on my new laptop, where I typed :

gpg --import cleComplete.gpg.asc

Here, gpg ask me for the key’s passphrase, but it doesn’t recognize it
(asking 3 times), and finally fail to import the secret key.

I tried also import with the option ’--pinentry-mode loopback’, typing the
passphrase in the terminal, but it doesn’t succeed either, with error
message : error sending to agent: Bad passphrase

I’ve tested the same file cleComplete.gpg.asc on another Debian 12 system,
and the importation succeeded on the first try.


    With regards,
        Fred.
