I have a 6500 IDSM2 at 5.1(4) + S261. When I attempt to upgrade to S267 or S268, I get the error msg:
Error: execUpgradeSoftware : Error status returned with status str Internal Error.
I have rebooted the IDS - no difference. I'm using "upgrade http:" with http sw which has always worked in the past. What should I look at?
