When dnf can't find a package to install, it says (for instance):
No se encontraron paquetes para intalar: 'python3-sphinx'
This is incorrect; presumably it was supposed to say "instalar" (i.e., with an 's' inserted into the third character spot). "instalar" is "to install"; "intalar" is not a word that I'm aware of.
