ubuntu - 安装percona时出错

Question

我使用这个命令

wget https://repo.percona.com/apt/percona-release_0.1-4.$(lsb_release -sc)_all.deb
dpkg -i percona-release_0.1-4.$(lsb_release -sc)_all.deb

sudo apt-get 更新
并得到了这个错误

N: Ignoring file 'percona-release_0.1-4.xenial_all.deb.1' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'percona-release_0.1-4.xenial_all.deb' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
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.

我用 https://www.percona.com/doc/percona-server/LATEST/installation/apt_repo.html教程和虚拟环境。错误在哪里以及如何解决？

输出显示您已离开 Percona 版本 .deb /etc/apt.sources.d 内的文件- 扫描目录中的文件。
将其从该文件夹中移出到其他位置，有关 Percona 版本的消息将消失。

您遇到的错误与您已安装的 PPA 相关(与 Percona 存储库无关)。您可以找到有关 how you can remove it 的信息，其中一个选项是 sudo add-apt-repository --remove ppa:whatever/ppa
