I'm using hosted dependencies in my pubspec.yaml file running an instance of pub_server server but after 1.14.0 version pub commands stop working.
I reproduced the problem with this pubspec.yaml (my_pub_server:9091 is just an example):

name: hosted_error
version: 0.0.1
description: A simple console application.
dependencies:
  sqlbuilder:
    hosted:
      name: sqlbuilder
      url: http://my_pub_server:9091

If I run pub --trace -v update with 1.13.2 version, the dependency is resolved correctly:

hanselmo:hosted_error hans$ pub --trace -v update
FINE: Pub 1.13.2

instead if I run with the pub command with the 1.14.0 version, pub resolves correctly:

http://my_pub_server:9091/api/packages/sqlbuilder

but then downloads the package from the wrong server:

https://pub.dartlang.org/packages/sqlbuilder/versions/1.3.4.tar.gz

@nex3 Did pub change anything in how it works with the server in 1.14?
@mkustermann Could this point to an issue with pub_server?

We haven't changed much in package:pub_server or package:pub_dartlang_org for a while. So I suspect that this might be a pub client issue (package:pub_server is unaware of the hostname pub.dartlang.org whereas the client has this hostname baked in, so seems very likely to me that something goes wrong)

One thing to note in the original bug report is that the first example with the old version of pub is actually not downloading anything, it uses a cached version of the package, whereas the second version is downloading something.

Let me know if I should help debugging this.

These are the outputs of both 1.13.2 and 1.14.0 after a pub cache cleaning.
Hope it helps, let me know if you need more info...

I haven't had time to dive into this yet, but based on the difference in behavior between pub versions I suspect it's a bug in the pub client rather than the server.

@fromlabs Just in case, can you manually request http://my_pub_server:9091/api/packages/sqlbuilder and paste the output here?
