my Ubuntu isn't installing Balena Etcher

[yahuda-sudo]

While installing Balena Etcher into my Ubuntu terminal I got an Error notice "Some packages could not be installed & requested an impossible situation" because the following packages have unmet dependencies: balena-etcher : Depends: gconf-service but it is not installable Depends: gconf2 but it is not installable Depends: libgconf-2-4 but it is not installable Do you have a recomended method or a quick solution for my problem ?
