Je ne sais pas du tout comment cela s'est passé ni comment y remédier. J'ai gnupg, gnupg-agent, gnupg-pkcs11-scd, gnupg2, gnupg-curl, gnupg-pkcs11-scd-dbg installé.

Effacez APT cache et régénérez-le:

Sudo apt-get clean
Sudo mv /var/lib/apt/lists /tmp
Sudo mkdir -p /var/lib/apt/lists/partial
Sudo apt-get clean
Sudo apt-get update

Il existe peut-être un lien ou un fichier non valide dans le répertoire /etc/apt/trusted.gpg.d/

Vérifiez que le répertoire contient des fichiers et des liens valides, par exemple:

# ls -L /etc/apt/trusted.gpg.d/* > /dev/null
ls: cannot access '/etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg': No such file or directory

Par conséquent, recherchez le package qui doit contenir le fichier

# dpkg -S /etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg
live-net-archive-keyring: /etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg

et prenez certaines des actions suivantes:

le réinstaller

# aptitude reinstall live-net-archive-keyring

ou réinstaller tous les trousseaux installés

# aptitude reinstall $(dpkg -l '*keyring' | awk '$1 == "ii" {print $2}')
The following packages will be REINSTALLED:
debian-archive-keyring gnome-keyring live-net-archive-keyring siduction-archive-keyring

ou supprimer le lien ou le fichier non valide

# rm /etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg
