3. bash dotnet-install.sh --verbose

Expected behavior

Install is successful

Actual behavior

Environment data

dotnet --info output: Irrevelant as the issue is with the install script

Same issue happens when specifying --version 2.0.0 or --shared-runtime. Can be worked around by specifying runtime as --runtime-id rhel.7.

@Nezz @omajid @khyperia The https://dot.net/v1/dotnet-install.sh public location has been updated with this fix.

[khyperia]

Can someone try out a fix to this: https://raw.githubusercontent.com/johnbeisner/cli/UpdateInstallScriptSH/scripts/obtain/dotnet-install.sh

It still prints out the following errors, but it successfully installs.

./dotnet-install.sh: line 123: VERSION_ID: unbound variable
./dotnet-install.sh: line 175: VERSION_ID: unbound variable
./dotnet-install.sh: line 183: VERSION_ID: unbound variable
