我已使用以下网址向Artifactory添加了debian-varnish41-remote存储库：https://packagecloud.io/varnishcache/varnish41。测试按钮说一切正常。
在客户端，我成功运行了这些命令：
sudo sh -c "echo 'deb https://<my-artifactory-server>/artifactory/debian-varnish41-remote trusty main' >> /etc/apt/sources.list"
curl -L https://packagecloud.io/varnishcache/varnish41/gpgkey | apt-key add -
sudo apt-get update
但是sudo apt-get install varnish最终会出现HTTP 400错误（错误400是错误请求）。
$ sudo apt-get install varnish

设置绕过HEAD请求具有相同的结果。
现在，我们在尝试进行故障排除时测试了以下内容：
Artifactory是否具有限制该回购下载的权限？
尽可能降低Repo权限。我们可以从浏览器下载软件包而无需登录Artifactory。所以这似乎不是问题。
回购中的版本或包文件是否不同？
我们尝试查看Varnish和Artifactory提供的InRelease和Packages文件，看看它们是否有任何不同之处。它们都是相同的。看来Artifactory只会转发远程位置的文件。
该网址实际上是否可用？
使用上述URL直接从Artifactory下载包有效：
$ wget 'https://<my-artifactory-server>/artifactory/debian-varnish41-remote/pool/trusty/main/v/varnish (4.1.9-1)/varnish_4.1.9-1~trusty_amd64.deb'

该网址有空格和几个括号。这会弄乱网址吗？
查看apt-get用于下载软件包的URL似乎并不表示存在任何差异：
Artifactory的：
$ apt-get download --print-uris varnish

$ ls

最后一个小标题是我们对这个问题的主要关注。 Artifactory处理URL中的空间是否很好？
非常感谢你对此的帮助！
