只是为了让您知道我对 Linux 还很陌生。
我刚刚从 Ubuntu 19.10 跳转到 Ubuntu 20.04.1 LTS，因为我认为 VirtualBox 不会有问题。 升级完成后发现VirtualBox不见了，我尝试按照官网和other sites上的说明安装它。
我不知道你们到底需要什么来帮助我解决问题，所以这里有一些信息：
这是我执行 sudo apt update 时出现的：

我做到了

$ wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -
和
echo "deb [arch=amd64] http://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contrib" | \
sudo tee -a /etc/apt/sources.list.d/virtualbox.list
没有任何问题。
我希望每个人都有美好的一天:)
