Cisco Network Assistant upgrade IOS failure...

[amron2008]

"Failed to execute the command archive download-sw /overwrite /http iosFile" when trying to upgrade IOS using CNA 5.8 (9) on a C2960-24TT-L.

I also get this failure in CLI mode when using the "archive download-sw /overwrite..." command.  The only work around I know of is to recursive delete the flash and then the command runs successfully.  Probably due to the free space, although the tar size is still smaller than the available free space when there are files already in the flash.  But that's still what I gotta do to make it work.

How do I get this to work using CNA?  Has anybody been able to do this?

Thanks.

My current work around using CNA is to:

1. Upgrade IOS from 12.2(35) to 12.2(58).

2. Upgrade IOS from 12.2(35) to 12.2(50).

3. Downgrade IOS from 12.2(50) to 12.2(35) then upgrade to 12.2(58).

This seems to be a work around for me.  I haven't tried upgrading 12.2(25) yet, but I suspect it will behave similarly.
