No sé qué puede ser, pero como primer remedio puedes tratar de instalar synaptc. En un terminal:
sudo apt-get install synaptic
Synaptic es una aplicación gráfica que también sirve para instalar programas.

Antes que nada gracias por su tiempo, le comento que instale synaptic pero, al querer abrirlo me marco el mismo error:

E: Línea 56 mal formada en la lista de fuentes /etc/apt/sources.list (análisis de URI)
E: No se pudo leer la lista de fuentes.
Vaya al diálogo del repositorio para corregir el problema.
E: _cache->open() failed, please report.

Corrige la linea 56 del archivo /etc/apt/sources.list. En el foro hay información de sobra sobre como hacerlo, no te será difícil encontrarla.
