If I use other file browser it is very simple use as root / sudo. 
For example I write in terminal:
sudo nautilus     (is is possible in Ubuntu desktop)
sudo nemo      (Is ti possible in linux mint)

But open as root is extremely difficult in dolphin in Kubuntu.
Kubuntu blocking using as root. 
But exist solution.

Can you please add feature in terminal? Actually it not working
sudo doplhin

Can you please repair it?

Thank you very much

My dolphin version
dolphin 24.08.1

Please make sure the kio-admin package is installed. Then you should be able to run "dolphin admin:///" in order to use Dolphin as root.

So there is definitely an issue on your system. kio-admin is installed but Dolphin is not seeing it. Other than making sure the system is up to date and rebooting, I'm not sure how else to troubleshoot this.

If you are using Dolphin 24.08.1 as mentioned in your bug report, then there is some sort of version mismatch in your system packages occurring, since that video shows that kio-admin version 23.08.5 is installed.

If all version mismatches are resolved and there is still an issue, then the Kubuntu folks would need to provide support for that. Those are older software versions still being provided by that distribution - KDE developers would need bug reports to be reproducible on currently-released software versions (24.12.3 is the most current for Dolphin and kio-admin) in order to investigate.

Thanks for understanding!

Thank you very much John for answer.
I contacted Kubuntu developers based your advice.
