Full Upgrade Status

Running a full upgrade in my lubuntu 20.04 distro, I went to a Locked status telling:

  • Status: Waiting for configuration file prompt *
    Last message in the process was: “Preparing the configuration grub-common” (“Preparando la configuracion grub-common” in Spanish because that is the installation language)
    uname -a shows me this:
    Linux Pinky 5.4.0-100-generic #113-Ubuntu SMP Thu Feb 3 18:43:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
    Please let me know how to proceed to fix this!!
    Thanks in advance!
