Estou tentando conectar meu computador executando o Ubuntu 20.04.1 a um switch Ethernet. Quando eu conecto o cabo, Configurações-> Rede mostra Conectado-100 Mb/s. De ifconifge em outros lugares, posso ver que a interface Ethernet eno1agora tem um endereço IP, uma rota padrão e um endereço DNS que são obtidos através do DHCP. No entanto, ainda não é possível navegar. Quando inicializo o mesmo computador usando um Linux live USB (não o Ubuntu), ele está conectado corretamente ao mesmo dispositivo usando o mesmo cabo Ethernet. Também tentei atribuição de IP estático, sem sucesso. Não consigo descobrir o que está faltando. Eu coletei detalhes de log usando journalctle estão anexados abaixo. Uma coisa que parece estar faltando nos logs é CONNECTED_GLOBAL, que vi em outras conexões. No entanto, não tenho certeza se isso tem algum efeito. Agradecerei muito qualquer ajuda para resolver isso.
Aqui estão os detalhes do registro. Também nos logs, você pode ver que não é possível conectar-se a daisy.ubuntu.com.
