很抱歉我以这种格式发布了文件...我的声誉还不足以发布文件本身。我已经尝试过这些命令了。
sudo apt-get -f install
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get clean
我也尝试安装这个
sudo apt-get install ppa-purge
但它没有安装。相反它说
dpkg: error processing package mysql-server (--configure):
dependency problems - leaving unconfigured
mysql server很好。我甚至列出了我拥有的 ppa，但我看不到带来这个问题的那个。我试过很多其他的东西。拜托，在我淹死之前救救我的独木舟
答案1
您的sources.list文件似乎已损坏。下面分享了一个示例。您可以用示例sources.list替换您的内容。sources.list
打开当前的
sources.list：sudo nano /etc/apt/sources.list要么纠正产生错误的行，要么直接从示例中复制并
sources.list用它替换您的内容。接下来，从键盘上按下Ctrl+ O，然后Enter最后按下Ctrl+ X。
例子sources.list：
deb http://us.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
另外，要消除遗留的错误，首先检查ppas系统中当前安装的所有内容：
ls -l /etc/apt/sources.list.d/
ppas通过删除相应文件来移除导致错误的*.list。不用担心，您可以ppas在稍后使用重新添加这些文件sudo add-apt-repository。
现在，使用以下方法更新您的来源：
sudo apt-get update
有更好的方法删除ppas。由于您无法安装ppa-purge，因此我建议使用上述方法。
