Continuo lendo muitos problemas semelhantes, mas as soluções e recomendações não são bem-sucedidas para mim. Eu pensei que talvez fosse um problema de rede, mas nenhuma porta está bloqueada. Eu finalmente tirei de todo firewall e ainda é um problema. Eu mudei de fontes de servidores dos EUA, o servidor principal, e até mesmo deixar Update Manage procurar um melhor servidor. Ainda tem problema.
Aqui está o que eu recebo:

Tive que descansar por causa do incômodo de entrar e desabilitar os links, pois como novo usuário eu só tenho permissão para dois links. Difícil dar resultados com essa restrição!
Essencialmente foi uma resposta similar contínua de:

Por favor, forneça algumas orientações. Eu tenho usado o Ubuntu desde 2007 e nunca tive problemas para atualizar ou instalar novos lançamentos. Foram três dias trabalhando nisso. Agradecemos antecipadamente ...
