如何删除ppa

  • 772

我正在远程访问 linux 系统 [Ubuntu16.04 LTS]。很多事情似乎都搞砸了。我需要安装libgmp-dev，这会E: Sub-process /usr/bin/dpkg returned an error code (1)出错。在尝试了一些事情之后，我认为apt-get update可能会有所帮助，但sudo apt-get update会出现错误：

Err:18 http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial/main amd64 Packages
404  Not Found
W: The repository 'http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/mc3man/trusty-media/ubuntu/dists/xenial/main/binary-amd64/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

阅读一些帖子，似乎删除 ppa 是解决方案，但是我不确定如何从命令行执行此操作。这个流行的答案建议sudo apt-get install ppa-purge在删除 ppa 之前。但是sudo apt-get install ppa-purge再次运行会出错E: Sub-process /usr/bin/dpkg returned an error code (1)。

我想尝试该解决方案sudo add-apt-repository --remove ppa:whatever/ppa，但令人尴尬的是，我不确定要替换什么，whatever因为我从未安装过这些 ppas（我只能访问该系统）。

的输出ls /etc/apt/sources.list.d是：

aheck-ubuntu-ppa-xenial.list                 mc3man-ubuntu-xerus-media-xenial.list  nccl-2.1.15-ga-cuda8.0.list.save
aheck-ubuntu-ppa-xenial.list.save            multiverse.list                        opennms.list
blahota-ubuntu-texstudio-xenial.list         multiverse.list.save                   sublime-text.list
blahota-ubuntu-texstudio-xenial.list.save    myppa.list                             sublime-text.list.save
mc3man-ubuntu-trusty-media-xenial.list       myppa.list.save
mc3man-ubuntu-trusty-media-xenial.list.save  nccl-2.1.15-ga-cuda8.0.list

编辑：

当我apt-get update从 mc3man 运行很多 ppa 时，除了那个（amd64）之外，没有任何错误，删除所有这些作为grep mc3man *inside输出的文件是否安全/etc/apt/sources.list.d/？

mc3man-ubuntu-trusty-media-xenial.list:deb http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial main
mc3man-ubuntu-trusty-media-xenial.list:# deb-src http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial main
mc3man-ubuntu-trusty-media-xenial.list.save:deb http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial main
mc3man-ubuntu-trusty-media-xenial.list.save:# deb-src http://ppa.launchpad.net/mc3man/trusty-media/ubuntu xenial main
mc3man-ubuntu-xerus-media-xenial.list:deb http://ppa.launchpad.net/mc3man/xerus-media/ubuntu xenial main
mc3man-ubuntu-xerus-media-xenial.list:# deb-src http://ppa.launchpad.net/mc3man/xerus-media/ubuntu xenial main

编辑2：

mv mc3man-ubuntu-trusty-media-xenial.list mc3man-ubuntu-trusty-media-xenial.list.bak工作是因为我在代理后面，现在错误是：

E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
package-management updates ppa dpkg apt

    您可以尝试cd进入sources.list.d目录并运行grep到您从错误中知道的子模式，例如：

    grep mc3man *

    这将显示它找到的包含给定字符串的文件和行，例如

    afile.list: blah/mc3man/blah

    然后，您可以sudo add-apt-repository --remove ppa:whatever/ppa使用与字符串匹配的文件（在本例中，afile.list）按照建议继续
