A minha configuração do Fedora desapareceu devido a uma “atualização do yum” acidental

Question

Como reverter? Eu tentei yum history undo 143 e yum --skip-broken history undo 143 e recebi os seguintes erros.

Importante: Tudo o que me interessa é fazer com que meu kernel e o driver gráfico personalizado voltem ao estado original - o kernel padrão não inicializa e meus olhos doem do monitor do laptop cujo brilho não pode ser ajustado com as teclas Fn pelo menos.

O restante dos pacotes pode ficar ou sair como quiser, não importa. Então, se qualquer fruta que eu puder pegar, seria legal:

yum --skip-broken history rollback 142 output é um pouco diferente:
