如何在不使用sudo的情况下在Ubuntu上安装.Net Core？

Question

The current installation instructions for Ubuntu 14 require the use of sudo ( https://www.microsoft.com/net/core#ubuntu ). I don't have root permissions on a particular Ubuntu 12 server that I need to install .Net Core on. I have tried to download the Ubuntu files ( https://www.microsoft.com/net/download#core ) and install them manually but I get the following error when I run 'dotnet restore':

Failed to initialize CoreCLR, HRESULT: 0x8007001F

Answer 1

Running dotnet from the tar.gz works just fine for me on Ubuntu 14.

Running from the tar.gz or building from source does not work for me on Ubuntu 12. But Ubuntu 12 is not supported by dotnet , so I'm not surprised it does not work.

Not using sudo is not an issue, having old OS is.

Answer 2

According to this:

https://github.com/dotnet/cli/issues/2971

it's a permissions issue and the fix:

As soon as I do chmod +X to my binary (here it's tata) it works.

Answer 3

According to https://docs.microsoft.com/en-us/dotnet/core/linux-prerequisites?tabs=netcore2x you can use "The dotnet-install scripts are used to perform a non-admin install of the CLI toolchain". Although as mentioned results may vary depending on the linux os and version. I might recommend running a vm to test compatibilities with different versions if having issues. File permissions are also important.
