I get Package restore failed. Rolling back package changes for 'ConsoleApp1' while installing a new package. In particular I am trying to install the dropbox API, but I tried several other packages and get the same result.
I install by right clicking on the project and choosing Manage nuGet Packages... Then I select the package and click Install.
The NuGet is able to connect with the NuGet server as the package seems to download. The download information flashes on the screen pretty quick so I captured it with screen recording software to see if there were error messages. There were none.
I updated visual studio 2017 to latest patch level. My windows 10 machine is also at the latest level.
The project I am trying to install into is a freshly created Console App(.Net Core).
Here are the other questions I looked at:
Package restore failed. Rolling back package changes
does not have any responses because it is not a well developed question.
package restore failed rolling back package change for ' myproject' in vs 2017 .net mvc core project
Yet another poorly worded question with no viable answers.
Package restore failed. Rolling back package changes for 'myproject' in vs 2017 in MVC Core
That one is trying to update packages, not install new.
Nuget - Package restore failed. Rolling back package changes for 'WebApplication1'. 0
Seems to be for a custom package.
I am new to using Visual Studio.
To expand on #Michael Potter's answer, create a Console App (.NET Framework), NOT Console App (.NET Core).
The problem was that I am using Console App(.Net Core) Core is not compatible with Dropbox API.
I figured that out by opening NuGet Package Manager -> Package Manager Console and running Install-Package Dropbox-Api.
Then the error message about compatibility was on the screen plain to see.
To solve the problem I am switching to Console App (.Net Framework).
bring the version of the solution package to 1.1.3enter image description here

Trying to install the latest Aspose.Cells package in VS 2019. Had a buddy try the same thing, same error. Have a license. What am I missing?
Severity Code Description Project File Line Suppression State
Error The feed 'nuget.org [https://api.nuget.org/v3/index.json]' lists package 'Aspose.Cells.22.3.0' 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 'Aspose.Cells.22.3.0'.
I tested your scenario/case. I created a new console application in VS.NET 2019. Then, I clicked on Tools|Nuget Package Manager|Manage Nuget Packages… option. Now I searched Aspose.Cells (v22.3.0) after clicking Browse link. I then installed the latest version and it works fine. I do not get any error during the import process as well.
The issue might be due to NuGet Package Manager configuration on your end. You may clear NuGet cache and give it a try in your VS.NET again.
PS. I am working as Support developer/ Evangelist at Aspose.
I just created a .NET Core Web Application in VS2017 and I wanted to be able to serve a single page application. In order to be able to do that I tried to install the nuget package Microsoft.AspNetCore.StaticFiles. But my NuGet installer failed and threw the following error
Severity Code Description Project File Line Suppression State
Package restore failed. Rolling back package changes for 'MyApp'.
Right click on the project=>Properties and set TargetFramework to .net core 2.0(less than or equal to the packages version you are using)
build the project and then install whatever you want from nuget.
I tried to update my AWSSDK for windows with one released 1 DEC to test a new Lambda with C#.
But I got error message like this.
Product: AWS Tools for Windows -- Error 1722.
There is a problem with this Windows Installer package.
A program run as part of the setup did not finish as expected.
Contact your support personnel or package vendor.
Thanks for the report, and we apologize for the inconvenience caused.
As noted by others, for this install we changed how we install the toolkit and for some users this is causing install fails that we have not managed yet to reproduce in-house and are still trying to find root cause for.
Feel free to post your install log here (if you have it), or on the AWS forum thread posted above where we are tracking the problem and gathering data from affected users.
What version(s) of Visual Studio do you have installed, and was this an upgrade install from a previous version?
We released version 1.11.1.4 of the AWS Toolkit for Visual Studio to resolve the installation problems. You can download the latest version from https://aws.amazon.com/visualstudio/
I'm using Visual Studio 2015 community along with some other in our team. A mvc web application that I created works fine on my machine but when others get it to build, all packages download successfully but some of the core MVC such as Microsoft.AspNet.Mvc, Razor, etc don't install.
What was weird that on their machine, if they went into PM and downgraded the MVC package to 5.2.2 and then upgraded back to 5.2.3 it worked. But now when setting up the build on our build server, we get the same issue!
Any ideas why this bizarre behavior?
Didn't check that but why would that matter? When the Dev downgrades the version on 1 package and then upgrades back everything is as it should be
EDIT (4th Oct 2016) after investigating a bunch of things:
One of the developers at one point committed the "Packages" folder which sits at the root which had the "Microsoft.AspNet.Mvc" and other folders but without the dlls. This made the "Restore packages" not really "Restore" these as the folder already existed but when the build was run the artifacts weren't actually there in the folder to be moved into bin.
I deleted the packages folder, added it to gitignore and committed the change which made everything 'green'!
I have an issue with my TeamCity instance not retrieving version 2.5.15 of SlowCheetah from TeamCity. It restores all of my other nuget based dependencies just fine.
I added SlowCheetah to one project in my Solution via the Nuget Package Manager Console and it works fine locally. However when TeamCity tries to get the nuget package is complains with
[restore] Unable to find version '2.5.15' of package 'SlowCheetah'.
I've had a look at adding a nuget installer - https://johanleino.wordpress.com/2013/06/17/making-use-of-teamcitys-nuget-capabilities-part-2/
and this
http://sedodream.com/2011/12/12/SlowCheetahXMLTransformsFromACIServer.aspx
neither of which work.
Any ideas?
I believe you need to update your Nuget version on TeamCity.
