Problem to install package

Make sure that you have internet access and verify your package source.-saige-

If you look closely at the error message you posted, you'll see that www.nugent.org could not be resolved.

You may have other problems to resolve + your question relates to a pure DNS issue.

I see...

imac> dig +short www.nugent.org a
64.99.80.121

Select allOpen in new window

So... one of two possibilities... Your internal caching DNS is flakey/glitchy (tech term for works sometimes, fails sometimes)...

Or... nugent.org DNS is flakey/glitchy...

A temp work around, is to add a record for nugent.org + www.nugent.org to your /etc/hosts file + finish your install + remove the /etc/hosts entry (because leaving a perpetual hard coded DNS entry is a very bad idea).

Thanks to all.
David,
Sorry to that I've put this line

       64.99.80.121    www.nugent.org              # x client host

Select allOpen in new window

in hosts file (and then have rebooted the server), but I still get this error

try from a browser to connect to www.nuget.org until you can do this add-package will not work.

I have no problem to get into

https://www.nuget.org/

(on the server). But I am still getting this problem.

Did you verify your package source?

-saige-

What to verify? How to resolve the current error?

Verify your DNS resolution is working, so us dig/nslookup to verify your DNS is working, ping the site to ensure packets are flowing (which might fail if site blocks ICMP traffic), then visit via browser, as David Johnson suggested.

Tip: Always imagine everything is broken + start debugging at the lowest common denominator.

I get the below, on the server

In VS 2013, to verify the package source.

Go to TOOLS -> NuGet Package Manager -> Package Manager Settings:In the Options dialog, select Package Sources and verify that your nuget.org package source matches one of the two following urls:

V2 - https://www.nuget.org/api/v2/
V3 - https://api.nuget.org/v3/index.json

NOTE - Note that the V2 API is deprecated and does not work with NuGet 4+.

-saige-

since v2 is no longer functional.. is there a solid reason why you are not using visual studio 2017?  (community edition is free)

Saige,
What to adjust, due to the below problem (it does keep waiting)?
David,
I want to resolve problem in VS 2013.
