如何删除“ /etc/apt/sources.list.d/目录中的文件，因为文件扩展名无效？”

从13.10升级到14.04之后，每次安装，更新，升级等等时，我都会收到这些烦人的消息：

N: Ignoring file 'webupd8team-java-raring.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension 
N: Ignoring file 'bumblebee-stable-raring.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

如何解决消息中指出的根本问题？

编辑：有时，我会在上面的消息后附加其他消息：

W: GPG error: http://www.duinsoft.nl debs Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E18CE6625CB26B26
W: Failed to fetch http://ppa.launchpad.net/person/ppa/ubuntu/dists/karmic/main/binary-amd64/Packages  404  Not Found

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

E: Some index files failed to download. They have been ignored, or old ones used instead.

有时，我可能会其他人，但是我找不到确切的消息了。

要解决您的第一个问题，请在终端中运行此命令：

sudo rm /etc/apt/sources.list.d/*.disable

（禁用PPA时，较旧版本的软件包管理工具会保留这些文件。删除它们非常安全）

您的第二个问题来自旧的Karmic存储库。要找出在终端机中运行该程序的人：

cd /etc/apt

grep -rw karmic *

一旦知道了它来自哪个存储库，就可以很容易地禁用/删除它。

也许您应该尝试使用以下命令：

sudo sh -c "echo 'Dir::Ignore-Files-Silently:: \"(.save|.distupgrade)$\";' > /etc/apt/apt.conf.d/99ignoresave"

我在Ubuntu MATE 15.04中有一个类似的问题。后

sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"

和

wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -

和

sudo apt-get update

我收到此消息：

N: Ignoring file 'pgdg.listwget' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

我这样解决了：

sudo mv /etc/apt/sources.list.d/pgdg.listwget /etc/apt/sources.list.d/pgdg.list

就我而言，它正在为/etc/apt/sources.list.d/目录中的* .save文件提供消息。我删除了它们。现在，那里仅存在* .list文件。这些警告减少了。

[kubuntu 18.04]

我无法弄清楚为什么在似乎没有任何东西明确设置后缀.distUpgrade和后缀时会.save被忽略。

然后我发现其中apt-config dump | grep -i ignore有这些条目和其他条目：

Dir::Ignore-Files-Silently "";
Dir::Ignore-Files-Silently:: "~$";
Dir::Ignore-Files-Silently:: "\.disabled$";
Dir::Ignore-Files-Silently:: "\.bak$";
Dir::Ignore-Files-Silently:: "\.dpkg-[a-z]+$";
Dir::Ignore-Files-Silently:: "\.ucf-[a-z]+$";
Dir::Ignore-Files-Silently:: "\.save$";
Dir::Ignore-Files-Silently:: "\.orig$";
Dir::Ignore-Files-Silently:: "\.distUpgrade$";

我只是将那些狡猾的人改名为那些扩展名。（我选择了.orig）

我们还可以像这样解决此问题：

sudo mv /etc/apt/sources.list.d/webupd8team-java-raring.list.disable /etc/apt/sources.list.d/webupd8team-java-raring.list

这仅适用于单个文件。
