Error al instalar composer en produccion - Package itbz/fpdf is abandoned

Buen día, los molesto porque al querer actualizar la versión de Pilaga de 3.1.2 a 3.1.3 al instalar el composer da el siguiente error:
Package itbz/fpdf is abandoned, you should avoid using it. Use setasign/fpdf instead
Luego ,aborta la instalación.
Estoy usando Debian 8, apache2, php5 y postgresql 9.4

Agradecemos cualquier ayuda.

Nos dimos cuenta que no abortaba sino que es un warning.
Seguimos adelante y funcionó ok.
Muchas gracias
