Install script fails with: main: line 908: http_code: unbound variable

[viceice]

Currently the bash install script fails on ubuntu bionic and focal docker images:

DOTNET_VERSION=3.1.403
DOTNET_INSTALL_DIR=/usr/local/dotnet/${DOTNET_VERSION}
curl -sfL https://dot.net/v1/dotnet-install.sh | bash -s - --version $DOTNET_VERSION --install-dir ${DOTNET_INSTALL_DIR}

#5 16.67 dotnet-install: Note that the intended use of this script is for Continuous Integration (CI) scenarios, where:
#5 16.67 dotnet-install: - The SDK needs to be installed without user interaction and without admin rights.
#5 16.67 dotnet-install: - The SDK installation doesn't need to persist across multiple CI runs.
#5 16.67 dotnet-install: To set up a development environment or to run apps, use installers rather than this script. Visit https://dotnet.microsoft.com/download to get the installer.
