参考这个链接……这么短，靠谱吗？看看别的博客先

好像就是这么短。不管了先试试，希望别出问题

哦，apt-key 弃用了，坏

    wget -qO - https://package.perforce.com/perforce.pubkey | sudo apt-key add -
    sudo echo "deb http://package.perforce.com/apt/ubuntu focal release" > /etc/apt/sources.list.d/perforce.list

    wget -qO - https://package.perforce.com/perforce.pubkey | sudo gpg --dearmor -o /usr/share/keyrings/perforce-archive-keyring.gpg
    sudo echo "deb [signed-by=/usr/share/keyrings/perforce-archive-keyring.gpg] http://package.perforce.com/apt/ubuntu focal release" > /etc/apt/sources.list.d/perforce.list

换一下命令就好了
