你好,我正在尝试更新 ubuntu 16.04,它显示以下错误
W: The repository 'http://ppa.launchpad.net/n-muench/programs-ppa/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/n-muench/programs-ppa/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.
如果不修复此错误,我无法安装 filezilla。我尝试了所有的解决方案,但仍然出现相同的错误,请帮助我修复此错误。

您问题中的 PPA没有提供 xenial 的软件包。
你应该把它删除。
sudo apt-get install ppa-purge
sudo ppa-purge ppa:n-muench/programs-ppa
sudo add-apt-repository -r ppa:n-muench/programs-ppa
了解 PPA 的工作原理也可能有帮助 - 请参阅“什么是 PPA 以及如何使用它们?”。
