APIC Upgrade Failed

[Rem Markov]

Hey!

So I'm trying to upgrade all my APICs from 5.2(4e) to 5.2(7g).

However I receive an that the installation is failed but with not good explanation of why.

I receive this error massage:
The upgrade has an upgrade status of Failed - Installer Exited. The failure occurred at the Ready for next Upgrade stage of the install.

There's been an enhancement logged to improve that fault message as it doesn't really point towards any specific issue: CSCvy3305.   It's likely one of the pre-checks.  Ensure your APICs are dual connected & cabled correctly, and try to resolve as many Critical/Major faults as possible.  Failing that, suggest you open a TAC case and they will investigate the logs to determine why the upgrade is failing.

I have opened a TAC case and I'll update here!
