存储库类型和 PPA 之间的区别

  • 772

当我想安装 wine 时，我得到了以下列方式添加存储库的说明。

sudo apt-add-repository https://dl.winehq.org/wine-builds/ubuntu/

要安装 PlayOnLinux，我得到了类似的说明，但我需要在 URL 周围添加deb和""引用。为什么有区别？这还重要吗？

sudo add-apt-repository "deb http://deb.playonlinux.com/ bionic main"

为什么 PPA 根本不需要任何 URL？是否考虑到 URL 是https://launchpad.net/？

sudo add-apt-repository ppa:peek-developers/stable
software-installation repository ppa

    来自man add-apt-repository：

    SYNOPSIS
       add-apt-repository [OPTIONS] REPOSITORY

...

REPOSITORY STRING
       REPOSITORY can be either a line that can be added directly to
       sources.list(5), in the form ppa:<user>/<ppa-name> for adding
       Personal  Package  Archives, or a distribution component to
       enable.

       In the first form, REPOSITORY will just be appended to
       /etc/apt/sources.list.

    对于"deb http://deb.playonlinux.com/ bionic main"，它将逐字附加。这包括将发行版设置为bionic，即使您没有运行 Ubuntu Bionic 18.04。（请注意，playonlinuxmultiverse repo 中也提供了这一点。）

    对于https://dl.winehq.org/wine-builds/ubuntu/， add-apt-repository 将推断缺少的部分：

    • 输入 ( deb)
    • 分布 ( xenial, artful, bionic, 等)
    • 组件 ( main)

           In  the  second  form,  ppa:<user>/<ppa-name> will be expanded
       to the full deb line of the PPA and added into a new file in the
       /etc/apt/sources.list.d/ directory.  The GPG public key of the
       newly added PPA will also be downloaded and added to apt's
       keyring.

    这适用于ppa:peek-developers/stable. 是的，主机被假定为 Launchpad。

           In the third form, the given distribution component will be
       enabled for all sources.

    例如universe或multiverse

    有关 sources.list 格式的详细信息来自man sources.list.
