Encounter "Export-ESXImageProfile : Could not find a trusted signer" when generating Esxi-7.0U2a iso

[olympia5r5]

i was trying to generate  Esxi-7.0U2a iso file for Intel NUC11PAHi5 due to network adapter was not supported. 

Have downloaded :

VMware-ESXi-7.0U2a-17867351-depot.zip

Net-Community-Driver_1.2.0.0-1vmw.700.1.0.15843807_18028830.zip

Encounter the error message as below:

PowerCLI C:\> Export-ESXImageProfile -ImageProfile "ESXi-7.0.U2a-17867351-NUC" -ExportToISO -filepath c:\nuc-esxi\ESXi-7.0.U2a-17867351-NUC.iso

Can someone advise on this, thanks

Ciao 

Do you have tried to add to the command:

-NoSignatureCheck

Hi, thanks for the advice.

Able to create iso file after adding NoSignatureCheck

Export-ESXImageProfile -ImageProfile "ESXi-7.0U2a-17867351-NUC" -ExportToISO -filepath C:\nuc-esxi\ESXi-7.0U2a-17867351-NUC.iso -NoSignatureCheck

But is still cannot detect the network adapter. i have added Net-Community-Driver_1.2.0.0-1vmw.700.1.0.15843807_18028830.zip to Add-EsxSoftwareDepot

May i know what network driver will NUC11PAHi5 be using. It is showing "Intel® Ethernet Controller i225-V" from Intel website

Ciao

So the ESXi installation is successful on the NUC but the network card is not seen, or is ESXi not installed because there are no network cards?

Hi Ciao,

i can create the iso file after appending -NoSignatureCheck

As for installation, there is a built-in network card in NUC but the network card seem to be unstable.

i manage to install Esxi iso but have to reboot NUC twice every time in order to use it.

Not sure it is due to network card driver. There is no intel driver for Esxi. i am using "net-community"
