尝试更新包时发生握手错误

Question

在运行sudo apt-get update时，我得到以下输出：

Ign https://repo.varnish-cache.org trusty Release   
Ign https://repo.varnish-cache.org trusty/varnish-4.0 amd64 Packages/DiffIndex
Ign https://repo.varnish-cache.org trusty/varnish-4.0 i386 Packages/DiffIndex

E: Some index files failed to download. They have been ignored, or old ones used instead.

这意味着什么，我该如何解决这个问题？

Answer 1

这是ssl错误。

如果你访问主页，你会得到：

Repo.varns-cache.org不再是了。项目主页提供了获取发布版本、软件包等的详细信息。

如果然后转到主页：http://varnish-cache.org/releases/

你会看到

Deb和RPM存储库现在在Packagec头，用于Debian、Ubuntu、CentOS和Red的官方包现在位于Packagecloud.io的存储库中。Repo.varn-cache.org存储库的用户将不得不将其主机更改为新的存储库配置。有关详细信息，请参阅下面有关发行版的各节。

翻阅这一页，会意外地导致

https://packagecloud.io/varnishcache/varnish5/install

因此，说到底，您有一个ssl错误，因为回购不再存在，您需要更新您的repos ;)

Answer 2

若要修复，请删除旧的清漆缓存和损坏的APT回购源：

sudo apt-get purge varnish

sudo rm /etc/apt/sources.list.d/varnish*

sudo apt-key list | grep "varnish"

^(在左侧找到与清漆缓存匹配的GPG 'KeyID‘)

sudo apt-key del (Varnish-Cache GPG KeyID from above)

运行apt更新-您应该不会看到更多的错误：

sudo apt-get update

如果您希望通过正式的Ubuntu回购再次安装它：

sudo apt-get install varnish

请参阅：https://varnish-cache.org/releases/install_debian.html

如果您希望安装最新或开发版本，请遵循以下(或更新的指南)：

=> https://packagecloud.io/varnishcache/varnish5/install#bash-deb

Answer 3

我在Ubuntu14.04上遇到了一个类似的问题。我有这个..。

curl -s https://syncthing.net/release-key.txt | sudo apt-key add -
echo "deb https://apt.syncthing.net/ syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list
printf "Package: *\nPin: origin apt.syncthing.net\nPin-Priority: 990\n" | sudo tee /etc/apt/preferences.d/syncthing
sudo apt-get update
sudo apt-get install -y syncthing

..。这给了我这个错误..。

W: Failed to fetch https://apt.syncthing.net/dists/syncthing/stable/binary-amd64/Packages  gnutls_handshake() failed: Handshake failed

我唯一需要做的就是将https://apt.syncthing.net/更改为http://apt.syncthing.net/，因此它使用http而不是https。这不太安全，但是当您使用Ubuntu14.04这样的旧系统时，它是一个快速安装包的方法，Ubuntu14.04没有某些较新的APT repos期望客户端使用的所有最新https密码。
