Install Hangs

The build for one of my projects tends to hang for an inordinately long amount of time during a couple of the install and pre-build processes. It also seems to happen on the same steps each time. First it'll hang when installing some of the ruby gems. Particularly, it seems to happen when installing compass. It next hangs after having used nuget restore to install an entity framework package. It wouldn't particularly bother me, but I haven't been able to build yet as the two processes hang long enough to go over the 30 minute mark. The gem install takes about 20 minutes and the nuget restore seems like it might take even longer.

Locally neither are a problem, and watching the console window with verbose output turned on seems to show that the commands themselves (gem install and nuget restore) are hanging at points when nothing is really happening (such as right AFTER a successful request), which seems odd to me. I could be completely off the mark on that assumption though.

    Is nuget restore hanging every time or it has sporadic nature?

    Every time. With nuget restore It gets a few packages installed but eventually hangs part-way through.

    Do you have any custom NuGet package sources configured?

    I do. I am adding two sources to nuget when running it. One source from here,, and another from elsewhere.

    The console logs indicate that referenced packages from both of those sources look to be getting installed before it hangs.

    Where the second feed is hosted?

    I'm 95% sure it's custom feed problem. Sometimes default feed lags ( maintenance or specific build worker VM networking problems), but most of the time it works with predictable results. Just ran a test build:

    The second source is from my team's teamcity nuget repo, which is hosted in a Windows Azure VM (we've just found Appveyor and started moving some of our projects over). We haven't had problems with it lagging before though; this source is being used on another project here without incident.

    Could still be the culprit though. I'ma remove the references to our repos from the project and see how it runs, will report back with results.

    Yeah, let me know how it goes.

    Also, you might do a small fake project just to test how packages are being downloaded. Disable build and test stages and then use nuget install <package-from-teamcity> -Source <team-city-feed> as a build script.

    Seems that the problem with nuget was a problem with the credentials I was using. I didn't catch it because the line got hidden somewhere between 500 lines of output, and it was hanging at a rather nondescript place. Got that fixed and nuget is working beautifully.

    Could you please share how did you solve NuGet credentials problem? It seems there is a similar problem:

    Thank you!

    Hm, when I click that link it doesn't seem to load, so I'll share here. Not sure if it'll help either, since it was actually a dumb blunder on my part, but here goes:

    I'll start right off and say that the solution for me was to double-check the credentials I was supplying since I had messed up and was supplying a wrong username. I took a couple steps to get to the solution though, and that might be a help.

    Step 1) I turned on verbose output during the nuget restore, nuget restore -verbosity detailed, to get a better handle on where the problem might be occurring.

    Step 2) I created a couple of empty projects that just pulled in references from nuget, each using just one of my custom nuget repos. This allowed me to see exactly which one was the problem. It also reduced the output to a more manageable size as I was pulling in less packages from each.

    Anyhoo, after step two I was able to catch, on one of those test projects, the following lines that I hadn't noticed before:

    1234 |    Please provide credentials for:
    1235 |    Username:

    When I saw that I did a bit more debugging, by echoing out some of environment variables before the nuget restore, like so:

      - echo %nuget_user% %nuget_password%
      - nuget sources add -Name "Repo Name" -Source https://all.the.url/stuff/nuget-wsdf234 -UserName %nuget_user% -Password %nuget_password%

    If I was using the gui I could have just double-checked there, but since I was using a yml file with encrypted/secure values this was easier. During the next build I was able to see that I had actually supplied the wrong credentials for one of my sources.

    Hope that helps.
