ip addr add não pode criar novos dispositivos (e isso provavelmente não foi sua intenção). Portanto, primeiro você precisa descobrir para qual dispositivo existente deseja adicionar um alias e, em seguida, usar seu nome em vez de eth0 .
Eu estou trabalhando no Ubuntu 16.04 LTS. Eu preciso de docker xdebug adicionar um alias à nossa interface com IP estático. Eu descubro o comando no manual que eu deveria executar
sudo ip addr add 10.254.254.254/24 brd + dev eth0 label eth0:1
mas eu tenho erro
Cannot find device "eth0" I didn't know what the device I should use. I connect to the enternet via Wifi ifconfig give me the next result.
