,但出现了以下错误:

E: Some index files failed to download. They have been ignored, or old ones used instead.
我跟着这线程的最佳答案,它解决了该问题。
但有人能解释一下问题是什么以及如何解决吗?
答案1
如果您收到此类错误,则意味着您的 IPv6 连接不稳定,或者服务器已死,或者找不到文件。目前正在处理:
http://[2001:67c:1562::13]/ubuntu/dists/raring-security/multiverse/binary-i386/
答案2
输出中可以看到,您的计算机正在尝试使用 IPV6 地址(例如 2001:67c:1562::13 )进行连接,这些地址与 IPv4 地址(例如 192.168.0.1)不同。您可以采用两种方法。一种 - 禁用 IPv6,然后这些脚步:
使用任何文本编辑器打开你的
/etc/sysctl.conf
(你需要这样做sudo
)。我个人会这样做sudo nano /etc/sysctl.conf
(nano
最简单)或sudo vi /etc/sysctl.conf
。添加以下几行:
net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1
运行
sudo sysctl --load
以应用更改。
第二种方法是暂时使用 ipv4 进行更新,而不是仅使用 ipv6 一次。
sudo apt-get -o Acquire::ForceIPv4=true update
第三种方法是使用 IPv6 DNS。例如,点击顶部面板中的网络指示器,选择Edit Connections
,然后针对您的特定 wifi 或以太网连接使用2620:0:ccc::2
dns,它OpenDNS IPv6 服务器。请确保选择“仅地址”选项
