Hi Azman, same issue here, but on FS7300.
In our case, we believe the problem was due to a canceled installation after the initial test (instead of choose resume after the warnings, we canceled). Once canceled, it's not possible to install any version, always getting "Failed to apply update package" error message.
We were on v8.7.0.2 trying to upgrade to v8.7.0.9. We also tried versions 8.7.0.7 and 8.7.0.10 with identical result.
The solution was to restart the node through the service mode. Afterward, we were able to upgrade to version 8.7.0.9 without any issues.
Hope this helps.
Regards,
Andrés Córdoba Rossi
