Try to sign my personnal deb repository

I have used some info from these threads too :

I run :
sudo -s pulp /bin/bash
export PULP_SETTINGS=“/etc/pulp/settings.py”
pulpcore-manager add-signing-service --class deb:AptReleaseSigningService katello_deb_sign ./sign_deb_release.sh 0B93…900

and get the permission denied
RuntimeError: b’gpg: signing failed: Permission denied\ngpg: signing failed: Permission denied\n’

:frowning:
