释放文件不存在

Question

当我在终端上运行update-manager命令时，我会得到这个错误“

W: The repository 'http://ppa.launchpad.net/colingille/freshlight/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/colingille/freshlight/ubuntu/dists/xenial/main/source/Sources  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

Answer 1

404 error建议，在该存储库中没有任何用于ubuntuX异种的包候选。这是因为ppa不存在于这里 (16.04)，正如您可以看到的那样。最新的软件包对应于15.04 (生动)。似乎WinUSB的PPA不再由作者维护。按照这些说明在16.04安装WinUSB。此外，请检查这个答案以获得WinUSB的替代方法。

为了解决这个问题，您可以简单地删除ppa：

sudo add-apt-repository -r ppa:colingille/freshlight
sudo apt update
