Chaque fois que j'essaie de mettre à jour (en utilisant Sudo apt-get update
) mon Ubuntu, j'ai ce problème:
W: The repository 'cdrom://Ubuntu 16.04 LTS _Xenial Xerus_ - Release AMD64 (20160420.1) xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: The repository 'ppa.launchpad.net/kirillshkrogalev/ffmpeg-next/ubuntu xenial Release' does not have a Release file.

Comment puis-je le réparer?
J'utilise Ubuntu 16.04 LTS
Pour résoudre ce problème à partir du terminal, vous devez supprimer/commenter cette source de référentiel de CD-ROM directement à partir de /etc/apt/sources.list
Sudo nano /etc/apt/sources.list
et commentez ou supprimez les lignes qui incluent cdrom. par exemple:
deb cdrom:[Ubuntu-Server 16.04 LTS _Xenial Xerus_ - Release AMD64 (20160420.3)]/ xenial main restricted
Essaye ça:
Ouvrez Logiciels et mises à jour et dans l'onglet Logiciel Ubunt décochez Cdrom avec Ubuntu 16.04 'LTS' Xenial Xerus ' dans la section - Installable à partir d'un CD-ROM/DVD.
