Hola no te preocupes. Yo haría un back-up de los datos y archivos, que no
quieras perder y actualizarla a 18-04.
Funcionar funciona pero estás a punto de que no se actualice más, y puedes
tener problemas de seguridad, ojo se trata de una actualización importante,
que debes realizar, seguramente en dos pasos, dos actualizaciones
parciales. Primero a 16 y luego a 18-04.
Configura el gestor de actualizaciones a versiones LTS, no obstante la
18-04 tiene soporte para 10 años.
Saludos
