“Scan or remediation is not supported on because of unsupported OS …” for certain operating systems

The VMware wrote this  workaround, so you can manually add the operating system to the list for VMware Update Manager.

1. Connect to your vCenter Server Appliance per SSH and log in
2. Create a backup of the vci-integrity.xml file:

3. Modify the vci-integrity.xml file by opening the file using vi editor:

4. Locate the <vci_vcIntegrity> ….. </vci_vcIntegrity> section
5. Enter edit mode by hitting the insert or the letter i button
6. Before the </vci_vcIntegrity> line, add the following lines, depending on the operating system configured in your virtual machine. If entering both versions of the same OS (ie: Windows 2019 AND 2022), see the below Note section

• For Debian 11 (32 bit):

  <supportedLinuxGuestIds>
    <debian11Guest/>
  </supportedLinuxGuestIds>

• For Debian 11 (64 bit):

  <supportedLinuxGuestIds>
    <debian11_64Guest/>
  </supportedLinuxGuestIds>​​​​​​

• For Red Hat Enterprise Linux 9 (64 bit):

  <supportedLinuxGuestIds>
    <rhel9_64Guest/>  
  </supportedLinuxGuestIds>

Some Linux have same issue, for that follow the list of all supported Linux Guest OS IDs
