Yesterday I had to upgrade a VCSA 6.5 U1b to U2e, but I got stuck in the process because the VCSA manager said this:

Latest updates already installed on vCSA, Nothing to stage/install

Hmm, thats not right… google, google, google
Seems that vmware changed the build numbering scheme, and they have an article about my issue:
https://kb.vmware.com/s/article/59659
Unfortunately the link to the attachement was dead 🙁 I had to create a case with vmware support to get the shell script.
So, to prevent this from happening again, heres the four lines thats in the script:

sed -i “s/if metadata[‘buildnumber’] <= _getBaseBuildNumber():/if int(metadata[‘buildnumber’]) <= int(_getBaseBuildNumber()):/g” /usr/lib/applmgmt/base/py/vmware/vherd/base/software_update.py
service-control –stop applmgmt
service-control –start applmgmt

Create a file on your VCSA in /root/ called buildversion.sh, paste the four lines above into it. Make it executable, run it, upgrade your VCSA.
