I can't update after changes in PPA Graphic Drives repository

[juanramoncastan]

After some changes made in "ppa:oibaf/graphics-drivers" repository give me the next warning message (spanish):

El repositorio «http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu bionic InRelease» cambió su valor «Label» de «Updated Open Graphics Drivers» a «Updated Open Graphics Drivers - since 2011!»
N: Esto debe aceptarse explícitamente antes de que se puedan aplicar actualizaciones para este repositorio. Consulte la página de manual de apt-secure(8) para obtener más detalles.

There is some way to "Accept explicitly" this change?
Thanks in advance.

I think the easiest way would be to remove that PPA and run
sudo apt update && sudo apt upgrade Then add the PPA again and try
sudo apt update again. Good Luck.
