This still does not work. Disable all packages but system, npk file does not fit. try to uninstall individual packages and says can not uninstall.
It cannot uninstall them because they came in the bundled file. But it normally can replace the ones marked for use by same packages of a different version loaded as separate npk files, dropping the complete bundle from the previous version.
Load up netinstal it see's the unit, click it, select your package, says installing. says complete, reboot still old package.
That simply means that the netinstall didn't actually work. How long, in seconds, it took from installing to complete?
Download the individual packages, only add the system package. reboot, log says not enough space to upgrade.
If everything but the system package was disabled when you did this, that's serious.
