I faced this issue before , and i did the following and my issue disappear
First step is to Install the locker vib manually
cd /tmp
esxcli software vib install -f -v /tmp/VMware_locker_tools-light_6.5.0-0.23.5969300.vib
Second step is to update
esxcli software profile update -f -p ESXi-6.5.0-20170702001-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-
depot-index.xml
then reboot .
