title: Unable to upgrade cdo to v1.9.7 on google cloud linux VM
body: <p>I am trying to install <code>CDO</code> v1.9.7 on my Linux VM on Google Cloud but it shows that the latest version available is 1.7. I am trying to regrid some netCDF files using <code>nctoolkit</code> but I can't do this with a <code>CDO</code> version &gt;= 1.9.4</p>
  <p>Please see the screenshot below:</p>

  <p>I have a personal linux machine which has v1.9.7 but I need the VM as its a GPU machine and I need to process massive datasets. Even though both are Linux I don't understand why its not working.</p>
