I'm upgrading a vcenter appliance 6.5 to a 7.0U3k.
While deploying the new appliance the process stops during the "RPM Installation" with the error that the IP used as Temporary IP is duplicated, which obviously is not.
The first run of the setup did not have this error but stopped later and so I started again the setup, after deleting the new appliance which was rolled out in the first attempt.
Below the error
A problem occurred during RPM installation: Error setting network. Details : 23/03/2023 13:10:58 [ERROR] Cannot run /sbin/ifup eth0 command. Unknown error.
