Probar:

Code: Select all

 sudo apt install bcmwl-kernel-source 

Reiniciar

se interrumpió la ejecución de dpkg, debe ejecutar manualmente «sudo dpkg --configure -a» para corregir el problema

Nada no funciona, se me bloquea el ordenador cuando llega al 92% y he tenido que volver a instalar el linux mint porque despues tampoco me arranca.
Alguna otra idea?

Está utilizando un núcleo antiguo 5.4.0-58. El núcleo actual es 5.4.0-135. Instale todas las actualizaciones disponibles en Update Manager.

Si eso no ayuda, es posible que desee probar Mint XFCE en lugar de Cinnamon.
