Upgrading from 8.51 to 9.02 and the install is failing at 27%. Looking at the C:\tmp\ca_uim\uimserver_ia_install file it is showing the following error:
nametoip failed: (4) not found, Received status (4) on response (for sendRcv) for cmd = 'nametoip' name = 'hub'
Release : 9.2.0
Component : UIM - INSTALL
Check the robot and hub.cfg files and make sure that there are no issues with any of the names or IP addresses listed there. If there are make adjustments, and restart the upgrade.
Note: hubname, robotname, domain, hubrobotname are case sensitive entries
