Docker sed: cannot rename /etc/sedl8ySxL: Device or resource busy

    Unfortunately this didn’t help me, but the site header graphics gave me a good chuckle in the middle of me banging my head against a wall.

  1. Hi,

    cp -f ~/hosts.new /etc/hosts
    does fail: cp: can’t create ‘/etc/hosts’: File exists

    I’m however able to solve that issue thanks to the following command:
    echo “$(cat ~/hosts.new)” > /etc/hosts

    Best regards
