Cisco Catalyst 3850 Upgrade Issue - Internal Error

While upgrading a pair of non-stacked 3850-48Ps, I encountered this error message:


[1]: % An internal error was encountered. Operation aborted.

I did have some space issues, so I deleted previous versions. Even that did not fix the issue. I tried installing it from tftp, to no avail.

Eventually, I ran the software install command with "new force"

software install file tftp://10.20.30.40/cat3k_caa-universalk9.SPA.03.06.09.E.152-2.E9.bin new force

Success. I rebooted both switches. One crashed on reboot, but rebooted cleanly afterward.
