如何将非官方存储库添加到 ubuntu

how can I add an unofficial repository to ubuntu

我必须将 http://download.opensuse.org/repositories/multimedia:/xiph/ 存储库添加到我的 ubuntu sources.list

写成here:

There are package repositories that can be added to the distro package manager. You can think of it as a “PPA” or whatever your distro calls this.

但是我不明白,我怎么能把它当作PPA。

您正在尝试将 opensuse 存储库添加到 Ubuntu。它们是不同的分布。为您要安装的软件找到 Ubuntu PPA。
