I am using nexus OSS 3.15.2-01 and its new instance.
Issue we are facing is with nuget proxy repos, if i try it manually curl nuget org on nexus server it reaches the URL.
I have created a seperate blob for nuget and new repo nuget_gallery, and provided the nuget org in proxy.
Now exepected is to fetch packages we want from nuget org, so what nexus is doing is it fetches the artifacts along with available versions but when i try to download it it says file not found.
From VS it says,
Severity Code Description Project File Line Suppression State
Error The feed ‘nexus prod [repo URL]’ lists package ‘Microsoft.AspNet.WebApi.Client.5.2.7’ but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.
Unable to find package ‘Microsoft.AspNet.WebApi.Client.5.2.7’.
How ever the version is fetched in nexus if we browse the repo but even when we try to download it says file not found (0 bytes)
Please suggest the resolution.
Thanks in Advance.
Have you checked the nexus.log file to see if there are errors recorded there?
There are no errors or exceptions we found in log.
There is only one warning which is “elastic search exceed and low disk watermark”, however there is still 45GB’s of free space available.
Do you have any idea what is the possible cause issue?
Proxy url https:// www.nuget.org/api/v2/ also reachable from the nexus server.
Because in log we are only getting
INFO [elasticsearch[C2E9DA26-EA391506-CF1FDBE4-][management][T#2]] *SYSTEM org.elasticsearch.cluster.routing.allocation.decider - [C2E9DA26-EA391506-CF1FDBE4-] low disk watermark [85%] exceeded on [gC80Xyjg][C2E9DA26-EA391506-CF1FDBE4-][/opt/TestNexus/sonatype-work/nexus3/elasticsearch/nexus/nodes/0] free: 45.5gb[12.5%], replicas will not be assigned to this node
I’ve got the same issue with lots of NuGet Packages from proxied Repositories on Nexus 3.17.0. e.g. Swashbuckle.AspNetCore. It would be great if a fix could be done as fast as possible.
Anything in the request.log for the failed packages?
The screen shows locally cached “false” indicating the file is not in NXRM.
I suspect you pulled the metadata but never pulled the file thus it’s showing up.
First try downloading from Nexus UI: [05/Jul/2019:14:48:12 +0200] “GET /repository/nuget-gallery/Swashbuckle.AspNetCore/4.0.1 HTTP/1.0” 404
Second try downloading with curl: [05/Jul/2019:14:51:08 +0200] “GET /repository/nuget-gallery/Swashbuckle.AspNetCore/4.0.1 HTTP/1.0” 404
With 3.15.2 it can download the artifacts…
Can you confirm “nuget-gallery” is proxy to nuget.org or relay what it’s a proxy to?
I have no issues downloading in 3.17.
Here’s the curl I tried: curl -o Swashbuckle.AspNetCore.4.0.1.nupkg http://localhost:8081/repository/nuget.org-proxy/Swashbuckle.AspNetCore/4.0.1
Also, if it works for you in 3.15.2, I suspect it’s a different issue than originally reported, as the original poster said they were having the issue in 3.15.2.
From my experience, nexus was not able to create the logs, for nuget or another repo.
When I restarted VM and brought up the nexus it started updating nexus about the activities done on related to nuget as expected.
Restarting vm resolved issue for me. I am not sure what went wrong.
Thanks for the support
We have the same issue today.
Request and error logs are clear but when CI tries to find the package we can see next error:
Failed to download package
'AutoMapper.Extensions.Microsoft.DependencyInjection.7.0.0' from 'https://our.nexus.registry/repository/nuget-group/AutoMapper.Extensions.Microsoft.DependencyInjection/7.0.0'.
Nuget Group contains 2 proxy repos and one of them is nuget.org
Nexus version is 3.18.1-01
Until that moment everything was fine.
Any suggestion why this happening from time to time and how to fix\workaround it?
What else information we can provide to you to help in diagnostics?
When you say request logs are clear, what is the response code for the request which failed?
I mean that for some reason Nexus returns 404 despite that package was presented in proxy repo.

When we started the next build for this parcticular project there was no changes in CI or project configuration and everything worked fine.
Just that package had the issue at that time?
There was nothing in the corresponding nexus.log at that time? e.g. remote could not be reached
Wow, there is next warning:
2019-10-22 12:34:59,348+0000 WARN [qtp661998269-138012] *UNKNOWN com.sonatype.nexus.repository.nuget.internal.proxy.NugetProxyFacet - Exception java.net.SocketTimeoutException: Read timed out checking remote for update, proxy repo nuget.org-proxy failed to fetch AutoMapper.Extensions.Microsoft.DependencyInjection/7.0.0, content not in cache.
Is there some latency between messages appending in log file? Because when I was inspecting this log for the first time (1-2 minutes after build was failed) I haven’t seen that message…
So since there’s a timeout reported, I suspect you’re hitting https://issues.sonatype.org/browse/NEXUS-18749 since this is NuGet group.
The reported workaround which may not work for everyone is to use seperate sources in your NuGet setup (effectively bypassing group).
You may also fiddle with the timeout settings in the “UI:Settings” capability, however, if I’m right about the bug, it’s not a reliable workaround as the bug could take an undetermined amount of time to resolve.
It is on the teams radar (as noted by team assignment) but the current NuGet focus is NuGet v3, so the bugs have been taking second place as that is pushed through.
Sorry for not better news…others may have different analysis.
BTW, there shouldn’t be any latency to speak of. You can tail the logs real time. It is possible there is more than one issue, but the one you describe to me sounds like that bug.
I ran into a similar problem and discovered it was an issue with the outbound web proxy. Our corporate proxy allowed “www . nuget . org”, but when nuget artifact downloads were attempted, a redirect to “globalcdn . nuget . org” was performed. Since “globalcdn . nuget . org” was not allowed on our corporate proxy, this caused artifacts to show up with 0 bytes since they could be found with the search against “www . nuget . org”, but the download against “globalcdn . nuget . org” was not working.
