我在我的 Ubuntu 16.04 服务器上运行“sudo apt -y update”，但出现以下错误：
# apt -y update

这可能是什么原因？我该如何解决这个问题？谢谢！
答案1
发生这种情况是因为sources.list您的机器上仍然有 Ubuntu 13.10 的文件：
您可以sudo -i在终端中使用并将以下内容（完整块）复制并粘贴到其中：
cat > /etc/apt/sources.list << EOF
deb http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu xenial-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial-backports main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse
#deb http://archive.ubuntu.com/ubuntu xenial-proposed restricted main universe multiverse
#deb-src http://archive.ubuntu.com/ubuntu xenial-proposed restricted main universe multiverse
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
EOF
这将覆盖您的/etc/apt/sources.list文件。之后您应该使用exit退出 root 权限。
如果您不希望启用所有软件包源，您可以从设置中的名为“软件和更新”的 GUI 小程序中进行更改。
那么你应该做以下义务：
sudo apt clean
sudo apt update
sudo apt dist-upgrade
答案2
希望我没有迟到
对于可能仍面临相同问题的人来说，上述解决方案对我来说不起作用。就我而言，根目录分区已满（已使用 100%），我使用了
df -h
cd /
du -sch * --exclude=home
检查哪些内容占用了磁盘空间。在我的例子中，根目录中有一个 mysql 数据文件夹的备份，占用了 9.1GB 空间中的约 3.7GB。我所做的就是删除 mysql 文件夹。但要小心删除的内容。
答案3
获取 sources.listUbuntu 源列表生成器/etc/apt/sources.list并用下载的文件 替换您的文件。接下来运行
sudo apt update
sudo apt dist-upgrade
