当我用 更新时sudo apt-get update
,我得到了这个:
N: Ignoring file '20auto-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension
W: The repository 'http://ppa.launchpad.net/lucid-bleed/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/lucid-bleed/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.
我的问题是:
这是什么错误以及我该如何理解它。
我该怎么做才能解决这个问题。
答案1
该错误是由于文件夹中的文件20auto-upgrades
被命名所导致的。20auto-upgrades.ucf-dist
/etc/apt/apt.conf.d/
要修复它,请打开你的终端并输入以下内容:
sudo mv 20auto-upgrades.ucf-dist 20auto-upgrades
然后做:
sudo apt update && sudo apt dist-upgrade
