Looks like deleting the "NuGetFallbackFolder" fixed the issue. Any idea what the problem was?

[wli3]

how did you install SDK via tar.gz or apt-get? install via tar.gz might have this problem when you did not run it with sudo when the location is a sudo location.

[mrlife]

I used the macOS "Installer" from: https://www.microsoft.com/net/download/dotnet-core/2.1. I think it had a .pkg extension.

[cuevaskoch]

I'm facing the same error on ubuntu updating to apt-git. I renamed the folder to NuGetfallbackFolder.bak, and the SDK still complains about it but allows me to continue

[wli3]

@jrkoch @mrlife it should be some permission mismatch. The end goal is expand nugetfallbackfolder with correct permission. To fix it, you could run any dotnet command other than help/info with sudo. However, i am still investigating why this issue happens in the first place. 1. fallbackfolder should expand during installer with sudo. Did it get interrupted? 2. when it find no permission to expand, SDK should try to expand it under ~/.dotnet folder

[wli3]

Similar issue here, but on Windows

https://github.com/dotnet/cli/issues/9842

[cuevaskoch]

It didn’t get interrupted in my case. I am facing it on two Ubuntu
installs, both running 18.04 upgraded from 17.10. And both had the dotnet
2.1 preview installed and have been kept up to date via the apt
repositories.

Responding to questions on other issue @livarcocc:

How is dotnet being installed? Msi? Zip?

Msi install

When prompted for admin permissions, are you allowing it?

In the installer? Yes.

The fallback folder should be expanded by the msi during installation. Something is either causing it not to happen or it is happening and we are failing to write the sentinel file that tells us it did happen.

Do you happen to have a DOTNET_SKIP_FIRST_RUN_EXPERIENCE environment variable set to true?

No, it is not set.

[jtsom]

Also happening on a brand new MacOS system, first time install of latest SDK (2.1.400). Any dotnet command results in:

-> % dotnet restore

Permission denied to modify the '/usr/local/share/dotnet/sdk/NuGetFallbackFolder' folder.

Here are some options to fix this error:
----------------------------------------
1. Re-run this command with elevated access.
2. Disabled the first run experience by setting the environment variable DOTNET_SKIP_FIRST_TIME_EXPERIENCE to true.
3. Copy the .NET Core SDK to a non-protected location and use it from there.

The sdk was installed from the MacOS package installer on a fresh system.

I tried using a 'sudo dotnet' command but now I'm getting multiple exceptions:

-> % sudo dotnet tool

Well, turns out it looks like it was the install of Trend Micro Antivirus. I had the IT department uninstall it and the sudo tool command went through without a problem....

[trampster]

If you follow the advice and run build as root using sudo once then your obj/bin folders will be owned by root and your normal build will fail.

Please fix this properly, building should never!!! ever require admin rights, this is so very, very, very wrong.

This cache should be in a location and with permissions that non sudo users can access.

[tmasabari]

I faced the similar issue on Windows 7 laptop where the dotnet commands were running successfully. This problem appeared suddenly. When I tried to run the same command in Administrator mode as described, packages cache got updated. So package cache management is the culprit?

Configuring...

A command is running to populate your local package cache to improve restore spe
ed and enable offline access. This command takes up to one minute to complete an
d only runs once.
Decompressing 100% 40101 ms
Expanding 100% 135531 ms

The dotnet.exe is executing well once the cache population is completed.

[bitcoinbrisbane]

I received this error because I set my Environment to production (to try fix another issue). The below fixed it for me

On Linux
export ASPNETCORE_ENVIRONMENT=Development

MacOS and Windows see
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/environments?view=aspnetcore-2.1

[Imartinn]

I'm facing the same error on ubuntu updating to apt-git. I renamed the folder to NuGetfallbackFolder.bak, and the SDK still complains about it but allows me to continue

This worked for me, the problem started after the update to dotnet core 2.2. I'm using Windows 10.

[TrevorFradsham]

I am too facing the same error. I have a newly configured ubuntu machine and after running:

~/code/c#/repos$ dotnet new console --output mvvm

and

~/code/c#/repos/mvvm$ dotnet restore

I get the following output error in both cases:

Permission denied to modify the '/usr/share/dotnet/sdk/NuGetFallbackFolder' folder.
Here are some options to fix this error:
----------------------------------------
1. Re-run this command with elevated access.
2. Disabled the first run experience by setting the environment variable DOTNET_SKIP_FIRST_TIME_EXPERIENCE to true.
3. Copy the .NET Core SDK to a non-protected location and use it from there.

Here is my kernel version:

I have been able to resolve my error by deleting the folder

/usr/share/dotnet/sdk/NuGetFallbackFolder

then completely uninstalling all dotnet components

dotnet-host dotnet-hostfxr-2.2 dotnet-runtime-2.2 dotnet-runtime-deps-2.2 dotnet-sdk-2.2

and reinstalling the dotnet-sdk2.2. Not really the way to fix the problem but it worked for me.

[k-rus]

I experience this issue on Linux Ubuntu 18.04.1 LTS. dotnet was installed with apt-get according to the instructions.
When I run dotnet run in a project, I get the following error, but it doesn't prevent for the application to start:

:~/Projects/ScApp$ dotnet run

Permission denied to modify the '/usr/share/dotnet/sdk/NuGetFallbackFolder' folder.

Here are some options to fix this error:
----------------------------------------
1. Re-run this command with elevated access.
2. Disabled the first run experience by setting the environment variable DOTNET_SKIP_FIRST_TIME_EXPERIENCE to true.
3. Copy the .NET Core SDK to a non-protected location and use it from there.

[honpray]

Same issue on Windows10 with .NET Core 2.2.104. I deleted the NuGetFallbackFolder then went to Windows Add/Remove Programs and clicked repair it. Well, it somehow is repaired. I checked the C:\Program Files\dotnet\sdk and the NuGetFallbackFolder is back with no error on each run now.

[roa-nyx]

Same issue for me, this happened to me right after I added the "Desktop environment for C++" workload to my VS2017 install. Maybe that messed with some permissions for that folder or it's ownership?

In my case I uninstalled all Core entries in Add/Remove, and then reinstalled from scratch, works fine now.

[tonyranieri]

I started having this issue on Win10 after updating to .NET core 2.2.203 from a previous 2.2 install (I'm not sure which but I think it was 2.2.104). I installed the SDK via the installer found on http://dot.net

To make the error go away I ran powershell as admin, killed all .NET process, VS Code, etc, and ran a dotnet restore in the source directory. After it completed I was able to go back into VS Code and non-admin powershell terminals and build without error.

How to Kill all .net Process?

[roa-nyx]

@asmaa3107 on windows: ctrl+shift+esc, Details tab, find all processes named dotnet.exe. Hit End Task. There is also a command, although I don't know it off-hand, and this should be good enough for you.

If there are no dotnet.exe processes you don't need to kill anything.

[vasilevp]

On Windows, changing permissions on C:\Program Files\dotnet\sdk\NuGetFallbackFolder worked for me (Properties -> Security -> Edit... -> Full Control for Administrators and Users).

[christoph-feb22]

I've updated to the latest sdk 2.2.301 and the error still occurs. For me the error only occures while trying to run a dotnet tool.
I'm using macOS 10.14.5

[HusseinElGanzory]

i give all permissions to a folder /usr/share/dotnet/sdk/NuGetFallbackFolder
sudo chmod -R 777 /usr/share/dotnet/sdk/NuGetFallbackFolder
then build project i worked very well

[trampster]

@HusseinElGanzory Thanks, however for the developers, it is extremely wrong that this is necessary, 777 is a extreme nuke it from orbit approach with very serious security implications.

There is no world in which it is OK for a build to by default require root access, ever, this should be a very high priority fix, the fact this issue still persists after 11 months is very concerning.

[jnsatterfield]

I have a similar issue under Ubuntu 18.10

This is not a fix, but is only being provided as additional information for anyone who might find it useful.

When issuing a build command on the command line, I would receive two messages:

1. The message regarding access to modify NuGetFallbackFolder being denied
2. A Build Failed message with the following info:

~/.nuget/packages/microsoft.aspnetcore.razor.design/2.2.0/build/netstandard2.0/Microsoft.AspNetCore.Razor.Design.CodeGeneration.targets(71,5): error MSB3374: The last access/last write time on file "obj/Debug/netcoreapp2.2/{PROJECT}.TagHelpers.input.cache" cannot be set. Access to the path '/shared/backups/projects/Development/Web/{PROJECT}/dotnet/obj/Debug/netcoreapp2.2/{PROJECT}.TagHelpers.input.cache' is denied. [/shared/backups/projects/Development/Web/{PROJECT}/dotnet/{PROJECT}.csproj]

The path located at /shared/backups/projects/* is located on an NTFS drive, usable by both Windows and Linux (dual-boot). As a point of curiosity, I copied the project to my home path, and took ownership of all of the files. All of my errors and warnings disappeared without changing anything else.

When investigating, I noticed that ownership for the obj/Debug/* files were all set to root:plugdev, with permissions of 770. Despite my account being a member of the plugdev group, write permissions to these files was being denied on the NTFS share.
