I posted a thread about my VRA 8.4.2 installation issues.
One of them was when I tried to update the support pack with the following error:
So after a lot of researching I found the solution for it, this is the steps:
1. download manually the support pack from the VMware download portal, the name of the file should by "vrlcm-8.4.1-PSPACK2.pspak"
2. go to - settings > Product Support Pack > Uplaod , now wait till the file will be upload successfully.
3. Go back to the failed request and retry - now it is should have work.
