Error installing edge microgateway in K8S

I followed instructions @ https://docs.apigee.com/api-platform/integrations/kubernetes/k8s-prerequisites#install_edge_microgat.... Got an error on the step 1.

curl -L https://raw.githubusercontent.com/apigee-internal/microgateway/master/kubernetes/release/downloadEdg... | sh -

[azureuser@microgateway-poc ~]$ curl -L https://raw.githubusercontent.com/apigee-internal/microgateway/master/kubernetes/release/downloadEdg... | sh - % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 1494 100 1494 0 0 3984 0 --:--:-- --:--:-- --:--:-- 3994 Downloading microgateway_v3.1.8_Linux_x86_64 from https://github.com/apigee-internal/microgateway/releases/download/v3.1.8/microgateway_v3.1.8_Linux_x... ... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 9 100 9 0 0 21 0 --:--:-- --:--:-- --:--:-- 21 gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now Downloaded into microgateway_v3.1.8_Linux_x86_64: sh: line 52: cd: bin: No such file or directory Add /home/azureuser to your path; e.g copy paste in your shell and/or ~/.profile: export PATH="$PATH:/home/azureuser"

After examining the shell script the script is trying to download the tar file from https://github.com/apigee-internal/microgateway/releases/download/v3.1.8/microgateway_v3.1.8_Linux_x.... We get a "not found" on this location.

Please let me know if this is the correct script and let me know the location of the tar file.
