我添加的新存储库从未被发现？

我正在运行 CrunchBang，输出如下uname -a

Linux sigh 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt2-1 (2014-12-08) x86_64 GNU/Linux

我的sources.list

apt-add-repository因此，每当我通过并运行添加任何新存储库时apt-get update，都会收到以下格式的错误：

W: Failed to fetch http://ppa.launchpad.net/conky-companions/ppa/ubuntu/dists/jessie/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/conky-companions/ppa/ubuntu/dists/jessie/main/binary-i386/Packages  404  Not Found

我认为这是因为我要求的版本jessie/main在大多数软件包中都不存在（？），但我不确定如何更改sources.list以防止这种情况发生并避免破坏我的系统。

有谁知道我怎样才能阻止它从 获取jessie/main？或者向我解释到底发生了什么，以便我可以让这些存储库正常工作？

add-apt-repository自动检测您的发行版代号，并且不提供执行此操作的选项。当然，它不能神奇地将 Debian 版本与 Ubuntu 匹配，并且要实现这一点，您必须编辑/etc/lsb-release，这可能会破坏其他东西。这是因为add-apt-repository调用SoftwareProperties.add_source_from_shortcut，这又使用aptsources.distro.get_distro()确定代号：

aptsources.distro.get_distro(id=None, codename=None, description=None, release=None)
Check the currently used distribution and return the corresponding distriubtion class that supports distro specific features.
If no paramter are given the distro will be auto detected via a call to lsb-release

（不，这不是我的拼写。）

因此，如果您愿意，请编辑/etc/lsb-release并更改DISTRIB_CODENAME为适当的 Ubuntu 版本（因为这是大多数 Launchpad PPA 的目标），例如trusty.

或者，您可以构建实际的线路。ppa:username/ppa-name翻译为：

add-apt-repository https://ppa.launchpad.net/username/ppa-name/ubuntu $(lsb_release -sc)

当然，您将替换$(lsb_release -sc)为trusty等。您还需要手动获取 GPG 密钥并添加它。这也有一个缺点，即不是在 中创建一个漂亮的新文件/etc/apt/sources.list.d，而是将该条目添加到/etc/apt/sources.list.

看起来您必须更改DISTRIB_ID和DISTRIB_CODENAME，以便它们的值匹配：

$ lsb_release -sc
trusty
$ sudo sed 's/trusty/wheezy/' -i /etc/lsb-release
$ lsb_release -sc                                
wheezy
$ sudo add-apt-repository ppa:conky-companions/ppa

当然，您添加的任何存储库前此更改仍需要手动更正。
