![为什么使用“sudo apt-get update”会收到错误消息?](https://linux22.com/image/1144169/%E4%B8%BA%E4%BB%80%E4%B9%88%E4%BD%BF%E7%94%A8%E2%80%9Csudo%20apt-get%20update%E2%80%9D%E4%BC%9A%E6%94%B6%E5%88%B0%E9%94%99%E8%AF%AF%E6%B6%88%E6%81%AF%EF%BC%9F.png)
尝试从终端更新时收到此错误消息:
Reading package lists... Done
W: The repository 'http://ppa.launchpad.net/ffmulticonverter/stable/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/ffmulticonverter/stable/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.
它指的是一个特定的应用程序,但整个更新变得毫无用处(我猜是由于这个错误)。
知道发生了什么事吗?为什么我无法更新操作系统?图形更新也不起作用。
答案1
此 PPA 没有适用于 Xenial 的版本,此存储库支持的最新版本是 Utopic。
