This script will compare running WaLinuxAgent version to the latest available in and if needed, will attempt updating it on the VM.

• RHEL 7.4/7.5/7.6/7.7/7.8/8.1/8.2
• CentOS 7.4/7.5/7.6/7.7
• Oracle 7.4/7.5/7.6/7.7/7.8/8.1
• SLES12 SP4
• SLES15 SP1
• Ubuntu 16.04/18.04
• Debian 10

• AzCli 2.0 installed on the machine you're running this script on https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest
• If enabled, you can run this script also through the bash Cloud Shell in your Azure Portal page.

Please note the following software, if missing, will be installed on your VMs:

• wget
• curl
• unzip
• python-setuptools
• temporarily, on CentOS and RedHat machines, the epel repository will be enabled

• Some VMs required a full reboot to update the status in Azure Portal. I didn't directly implemented this into the script, as such action may impact production and needs planning.

• download walaupdatelinux.sh on a machine where AzCLI is running and up-to-date:

  wget https://raw.githubusercontent.com/marinnedea/walaupdate/master/walaupdatelinux.sh
  

• make the script executable:

  chmod +x walaupdatelinux.sh
  

• execute the script:

  ./walaupdatelinux.sh
