Did you restart Update Manager? Sometimes this will solve issues.
And what is the version/build of vCenter?
the version of the Esxi must always be the same or less than the version of the vCenter.
Issues like this often occur if the client doesn't have the the vCenter Server root certificate installed.
Are you able to do the upload from en ESXi UI?
vCenter 184.108.40.206000, build 15132721
I've restarted the entire server.
Image is VMware-ESXi-6.7.0.update03-14320388-LNV-20190814
vCenter is 220.127.116.11000
I will install the March update 18.104.22.168300 and see if that makes any difference.
Updated vCenter to
I do appreciate all of your input.
Just to rule that out.
Did you verify that the ISO image is ok, i.e. by verifying its checksum?
Are you able to upload another image, e.g. the VMware default image, to see if it's related to the image, or a general issue?
I did check the MD5 checksum from Lenovo and it matches. I've also tried the VMware default ISO and have the same results.
I read somewhere that this issue appears related to the specific version of ESXi.
I did update vCenter to the latest and after 3 tries, was able to upload the Lenovo image. The base VMware image still fails.
Hosts managed by vCenter are:
VMware ESXi, 6.7.0, 10302608
VMware ESXi, 6.7.0, 13006603
VMware ESXi, 6.7.0, 8169922
VMware ESXi, 6.0.0, 5572656 (being retired)
Current Lenovo and Dell custom image is
VMware ESXi, 6.7.0, 14320388
I'll update the servers and see what happens.
I updated one of the ESXi hosts to the most recent Lenovo build and was able to upload the VMware base image to Update Manager just fine. Must be a version issue.
