Cada vez que intento actualizar (usando sudo apt-get update
) mi Ubuntu me sale este problema:
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.

¿Cómo puedo arreglarlo?
Yo uso Ubuntu 16.04 LTS
Para el error de ppa, vea esta pregunta . Por lo que publicaste, supongo que las actualizaciones de otras fuentes están funcionando bien, en cuyo caso no debes preocuparte demasiado por este error
