Eu não tenho ideia de como isso é reparado. Talvez você tenha ideia?

Eu verifico a fontehttps://mirror.yandex.ru/ubuntu/dists/focal/universe/ e não encontrar o pacote mc em
https://mirror.yandex.ru/ubuntu/dists/focal/universe/binary-i386/Packages.gz
mas encontre em
https://mirror.yandex.ru/ubuntu/dists/focal/universe/binary-amd64/Packages.gz
Isso significa que este pacote não está disponível para arquitetura x86, mas está disponível para x64.
se precisar instalar ''mc'', precisa baixar emhttps://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
Agora podemos executar ''mc'', mas não podemos executar ''apt full-upgrade'' , porque este comando instala o ''mc-data'' mais recente e remove o ''mc'' incompatível com ele.
