Based on the log, vpxd unable to connect to vpxd-svcs service which is a dependency service. I assume there might be other dependent services which are down.
stop all services using service-control --stop --all and start again service-control --start --all
Find which service failed to start. I remember patching may fail due to expired vcsa root password. You can take a snapshot and reset root password of vcsa and patch the vcsa again.
upload the software-packages.log
