Estou enfrentando alguns problemas em que o mysqldnão inicia, então gostaria de limpar ou (pelo menos) reinstalar seus arquivos para substituir os arquivos de configuração atuais pelos arquivos de estoque para que ele seja iniciado novamente.
Este é o conteúdo de journalctl -xeu mysqld.service:

Estou usando o Fedora 36 e instalei os seguintes pacotes
mysql80-community-release-fc36-1.noarch
mysql-community-common-8.0.30-10.fc36.x86_64
mysql-community-client-plugins-8.0.30-10.fc36.x86_64
mysql-community-libs-8.0.30-10.fc36.x86_64
mysql-community-client-8.0.30-10.fc36.x86_64
mysql-community-icu-data-files-8.0.30-10.fc36.x86_64
mysql-community-server-8.0.30-10.fc36.x86_64
mysql-workbench-community-8.0.30-1.fc36.x86_64
usando o site do MySQL .
O problema é que eu queria desinstalá-lo, mas ele quer remover muitas dependências, e o Fedora não permite deixar dependências instaladas se isso significar que elas estão quebradas.
