Jedes Mal, wenn ich sudo apt-get update
mein Ubuntu aktualisiere (benutze ), bekomme ich folgendes Problem:
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.

Um dieses Problem vom Terminal aus zu beheben, müssen Sie diese CD-ROM-Repository-Quelle direkt von entfernen / kommentieren
/etc/apt/sources.list
und kommentieren oder entfernen Sie Zeilen, die cdrom enthalten . z.B:

Versuchen Sie Folgendes :
Öffnen Sie Software & Updates und deaktivieren Sie auf der Registerkarte Ubuntu-Software die Option CD-ROM mit Ubuntu 16.04 LTS 'Xenial Xerus' im Abschnitt Von CD-ROM / DVD installierbar .
