Azure DevOps Self Hosted Agents VMSS: Unable to locate executable file: 'unzip'-CodePudding

I have created the VMSS in Azure

az group create --location eastus --name vmssagents

az vmss create --name vmssagentspool --resource-group vmssagents --image UbuntuLTS --vm-sku Standard_B1s --storage-sku StandardSSD_LRS --authentication-type SSH --generate-ssh-keys --instance-count 2 --disable-overprovision --upgrade-policy-mode manual --single-placement-group false --platform-fault-domain-count 1 --load-balancer ""

and created the Self Hosted Agent Pool in Azure DevOps

However, it is throwing the below error

Error: Unable to locate executable file: 'unzip'. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

Below is the Pipeline definition

Update: As suggested in the answer, I have recreated the VMSS with the below custom extension

az vmss extension set --vmss-name vmssagentspool --resource-group vmssagents  --name CustomScript --version 2.0 --publisher Microsoft.Azure.Extensions --settings '{"fileUris":["https://raw.githubusercontent.com/kavija/azure-devops-custom-installers/main/zip_install.sh"],"commandToExecute":"bash ./zip_install.sh" }'

CodePudding user response：

You could test the two workaround below.

1.You could add a bash command $ sudo apt-get install unzip before the failed task or at the beginning of your pipeline.

2.You could add an Azure VMSS extension to run the command sudo apt-get install unzip once the VMSS instance is created, and run the pipeline again. You could follow the steps below. 1)Create a .sh file in your public github repo with the command of sudo apt-get install unzip 2)Go to your VMSS resource and follow the three steps in the pic below

//script in step 2
az vmss extension set --vmss-name ubuntu --resource-group {Your Res Group} --name CustomScript --version 2.0 --publisher Microsoft.Azure.Extensions --settings '{ \"fileUris\":[\"https://{YourPublicRepo}/AddUnzip.sh\"], \"commandToExecute\": \"bash ./AddUnzip.sh /myArgs \" }'
