Can't install NuGet package Serilog.Sinks.* - asp.net

Question

I am facing a problem to install packages of Serilog.Sinks in an old project, e.g. when I try installing Serilog.Sinks.MSSqlServer I get the following error:
An error occurred while retrieving package metadata for Serilog.2.6.0
I have already installed package Serilog.2.6.0 and the process went fine, I tried running the code that uses this library and it works okay, but in case I try to uninstall this package I get the error:
Object reference not set to an instance of an object
Thus, I think that something might be wrong with Serilog.2.6.0 in my machine, since I cannot uninstall it or install any of its sinks, but I can't figure out the problem.
Details:
Visual Studio 2015
.NET Framework 4.5 Web Forms

If you can't uninstall your nuget via package manager console or with Nuget Package Manager, you still have the option to uninstall it. Open your package.config file.
Looks like this:
<packages>
<package id="Respond" version="1.2.0" targetFramework="net461" />
<package id="Serilog" version="2.6.0" targetFramework="net461" />
<package id="WebGrease" version="1.5.2" targetFramework="net461" />
</packages>
There you will find the id of Serilog your dependency with the version associated. Remove that line. And then unload your project, edit it, there you will find the HintPath of Serilog:
Looks like this:
<Reference Include="Serilog, Version=2.0.0.0, Culture=neutral, PublicKeyToken=24c2f752a8e58a10, processorArchitecture=MSIL">
<HintPath>..\packages\Serilog.2.6.0\lib\net46\Serilog.dll</HintPath>
<Private>True</Private>
</Reference>
Then the package Serilog could be uninstalled complete by manually.
Besides, if you re-install that package still get the same error after uninstall it, this issue should be more related to the NuGet rather than the package Serilog.
In this case, please try to uninstall the NuGet Package Manager for Visual Studio 2015 from Tools->Extensions and Updates, restart Visual Studio. Then install the latest version NuGet:
https://dist.nuget.org/visualstudio-2015-vsix/latest/NuGet.Tools.vsix
After the installation is completed, Reopen the Visual Studio in Administrator mode (right-clicked Visual Studio and started in Administrator mode), try to install that package again, check if it works fine.

The thing that worked for this case, from those I tried, is copying the references (.dll files) from another project where they're working fine. Thank you for your answers! :)

It works fine with me with the following package.config setting:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Serilog" version="2.6.0" targetFramework="net461" />
<package id="Serilog.Exceptions" version="4.1.0" targetFramework="net461" />
<package id="Serilog.Sinks.File" version="3.2.0" targetFramework="net461" />
</packages>
