So i tried to do this .. and it installed, but the image was not 'found':

To install additional .NET runtimes or SDKs:
https://aka.ms/dotnet-download
OKAY - so notice how I think it installed it to some weird/not default directory? well, I tried changing the command with specifying the directory to install into:
Command: curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --runtime dotnet --version 3.1.6 --install-dir /usr/share/dotnet
and now I get the following error:
curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --runtime dotnet --version 3.1.6 --install-dir /usr/share/dotnet
dotnet_install: Warning: Unable to locate zlib. Probable prerequisite missing; install zlib.(B

Command exited with code 1

So - i'm stuck. can anyone help please?
(of course, this could apply to any dotnet sdk version, I assume)

Hi Pure,
You have to use
sudo
to write to/usr/share/dotnet
folder. We use the following script to install the latest .NET Core on Linux:You can take the exact URL of distro on this page: https://dotnet.microsoft.com/download/dotnet-core/3.1 (Binaries -> x64).

hi @feodor - thanks heaps for the sample scripts. Your scripts work - awesome.
I went back and tried to use the microsoft
sh
scripts and they also work when I addedsudo
in:curl -sSL https://dot.net/v1/dotnet-install.sh | sudo bash /dev/stdin --runtime dotnet --version 3.1.6
curl -sSL https://dot.net/v1/dotnet-install.sh | sudo bash /dev/stdin --runtime aspnetcore --version 3.1.6
