package shim-signed 1.51+15.4-0ubuntu9 failed to install/upgrade: problemas de dependencias - se deja sin configurar

First...Why isn't it in Spanish?
It is difficult to have to explain something technical in another language.
Second I have Ubuntu 22.04.1 LTS 64 bits version
It gives error in the updates, there comes a time that indicates that an error occurred, without specifying more
