Problem: During an upgrade from VCSA 6.5 to 6.7, the following error was observed in the install log and prevented stage one of the upgrade from starting.
- error: sourcePrecheck: error in getting source Info: ServerFaultCode: Failed to authenticate with the guest operating system using the supplied credentials.
The root password entered into the wizard worked for logging into the appliance via the web interface (https://vcsa-ip:5480/) as well as via SSH.
Attempting to change the password or disable password expiration via the web interface did not work.
Solution: I was able to reset the password via SSH using the follow commands. Once done the wizard accepted the password and was able to complete stage 1 of the upgrade.
