Error at boot relatet dlogger.boot

[pixel24]

Hello everyone,

I’m new here, so first of all, a “hello” to the group. I’ve recently purchased two used ICX 7150-C12P 2X10G switches for my home and have installed them. I’m still a beginner and want to dive deeper into Ruckus products.

The two switches didn’t come with the latest firmware, so I’d like to update them. Current version on delivery:

I watched several videos from Ruckus and learned that if I want to update from a version equal to or lower than 08.0.70, I need an intermediate update to "08090." Therefore, I proceeded with the installation as follows:

en
copy tftp flash 192.168.83.141 mnz10115.bin bootrom
copy tftp flash 192.168.83.141 SPS08090k.bin primary

boot system flash secondary

copy tftp flash 192.168.83.141 SPS09010j_cd5ufi.bin secondary
boot system flash secondary

en
conf t
boot system flash secondary
write memory

Everything worked without any error messages. However, when I follow the boot process via the terminal, I always see the following messages when booting from the secondary image:

cp: can't stat '/.pkg/libpam/etc/*': No such file or directory  
                                                              Starting mgmt monitor scrit

What did I do wrong or forget to do?
