Failure to pickup and deploy package at the start of deployment

Legacy Uncategorised

Have been seeing this error a lot lately, where the NuGet package can’t be downloaded from the NuGet server to the machine I’m deploying to.

It claims the contents of the package can’t be verified, but I can browse through the package no problem with the Package Explorer, so I know the package is valid.

It seems to be looking for something in C:\Teamcity, which I don’t have on any of my machines, but that may be a red herring…?

Hi Neil,

This appears to be a problem with the NuGet server and has affected a few people - I have a long thread (unfortunately private) where we eliminated all the possible causes. I haven’t had time to investigate what the problem is, but the workaround is to use an alternative to the NuGet server.

If your machines are on the same network, you can simply use a Windows File Share (e.g., \YourServer\Packages). Octopus will work just fine with that. We found that the same package that failed under NuGet.Server worked fine under a file share, which is why we suspect the problem is in NuGet.Server.

I’ll be investigating the problem with NuGet.Server this week and I’ll update you when I have a result.

That’s great, thanks. I look forward to the resolution, keep me posted :slight_smile:

Hi,

Just to add that I’ve experienced this too, the solution for us is to rebuild the relevant package in Teamcity. Unfortunately our app contains quite a few solutions and sometimes more than 1 needs to be repackaged, but you can’t tell until you try to deploy which ones are ‘corrupt’.

In my opinion I think the issue is the NuGet server (we’re running v1.4.20609.9012), but can’t say I have any hard evidence at this point to back that statement up :frowning:
