“o pacote X requer Y, mas nenhum dos provedores pode ser instalado”

Question

Ao atualizar para o fedora 28, eu corri dois commnads

sudo dnf upgrade --refresh
sudo dnf install dnf-plugin-system-upgrade

Isso funcionou, mas o próximo comando     sudo dnf atualização de sistema download --releasever = 28 entrou neste

Error: 
Problem: package alsa-plugins-freeworld-lavcrate-1.1.5-1.fc27.i686 requires libavcodec.so.57, but none of the providers can be installed
- ffmpeg-libs-3.3.7-1.fc27.i686 does not belong to a distupgrade repository

Answer 1

If some of your packages have unsatisfied dependencies, the upgrade will refuse to continue until you run it again with an extra --allowerasing option. This often happens with packages installed from third-party repositories for which an updated repositories hasn't been yet published. Please study the output very carefully and examine which packages are going to be removed. None of them should be essential for system functionality, but some of them might be important for your productivity.

• In case of unsatisfied dependencies, you can sometimes see more details if you add --best option to the command line.
• If you want to remove/install some packages manually before running dnf system-upgrade download again, it's advisable to perform those operations with --setopt=keepcache=1 dnf command line option. Otherwise the whole package cache will be removed after your operation, and you'll need to download all the packages once again.
