verifico la fuente enhttps://mirror.yandex.ru/ubuntu/dists/focal/universe/ y no encuentro el paquete mc en
https://mirror.yandex.ru/ubuntu/dists/focal/universe/binary-i386/Packages.gz
pero encontrar en
https://mirror.yandex.ru/ubuntu/dists/focal/universe/binary-amd64/Packages.gz
Esto significa que este paquete no está disponible para la arquitectura x86, pero sí para x64.
Si necesita instalar ''mc'', necesita descargar desdehttps://launchpad.net
cd /tmp/
sudo apt remove mc-data
wget http://launchpadlibrarian.net/448485168/mc-data_4.8.23-1_all.deb
wget http://launchpadlibrarian.net/448485186/mc_4.8.23-1_i386.deb
sudo dpkg -i mc-data_4.8.23-1_all.deb
sudo dpkg -i mc_4.8.23-1_i386.deb
Ahora podemos ejecutar ''mc'', pero no podemos ejecutar ''apt full-upgrade'', porque este comando instala el ''mc-data'' más nuevo y elimina el ''mc'' incompatible con él.
