Ich nutze meistens:
esxcli software sources profile list -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml | grep 6.7.0-2021 | grep standard
und suche mir dann die aktuellste raus. esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p
ESXi-6.7.0-20210304001-standard
