Recentemente, um ícone de triângulo de aviso vermelho apareceu na barra de menus do meu laptop Dell XPS 13. Quando eu abro o menu, ele me diz que "as informações de atualização estão desatualizadas".
EupossoescolherCheckForAllUpdates,eissoiniciaumajanelachamada"Atualizando cache". Eu mostro o conteúdo final abaixo, embelezado para legibilidade.
Não tenho conhecimento de nenhum problema com a minha conexão com a Internet e não pude postar esta mensagem sem uma conexão com a Internet.
O que posso fazer para resolver esses problemas?
