J’ai ça depuis quelques jours après un apt update :
Notice: Missing Signed-By in the sources.list(5) entry for 'http://deb.debian.org/debian'
Notice: Missing Signed-By in the sources.list(5) entry for 'http://debian.drdteam.org'
Notice: Missing Signed-By in the sources.list(5) entry for 'http://www.deb-multimedia.org'
Notice: Consider migrating all sources.list(5) entries to the deb822 .sources format
Notice: The deb822 .sources format supports both embedded as well as external OpenPGP keys
Notice: See apt-secure(7) for best practices in configuring repository signing.
Je laisse passer en attendant qu’un script fasse le boulot ou je dois faire des trucs à la main (et si oui, quoi ?) ?
