Cannot start root mode Krusader, /usr/lib/x86_64-linux-gnu/libexec/kf5/kdesu not found or not executable. Please verify that kde-cli-tools are installed

[muh muh]

I can't start root mode in Krusader 2.8.1.

I am running:

Operating System: Kubuntu 24.10
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.6.2
Kernel Version: 6.11.0-13-generic (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 7840HS w/ Radeon 780M Graphics
Memory: 60.6 GiB of RAM
Graphics Processor: AMD Radeon 780M
Manufacturer: Framework
Product Name: Laptop 16 (AMD Ryzen 7040 Series)
System Version: AG

When I try Tools->Start Root Mode Krusader, and click past the warning about:

Improper operations in root mode can damage your operating system

a window appears that says:

Cannot start root mode Krusader, /usr/lib/x86_64-linux-gnu/libexec/kf5/kdesu not found or not executable. Please verify that kde-cli-tools are installed

So, I did this:

username-f16@Framework-16:~$ sudo apt-get install kde-cli-tools
[sudo] password for username-f16:

username-f16@Framework-16:~$

I checked and found this:

username-f16@Framework-16:~$ ll /usr/lib/x86_64-linux-gnu/libexec/kf6/kdesu
-rwxr-xr-x 1 root root 64176 Sep 11 00:58 /usr/lib/x86_64-linux-gnu/libexec/kf6/kdesu*

username-f16@Framework-16:~$ 

I executed this:

username-f16@Framework-16:~$ /usr/lib/x86_64-linux-gnu/libexec/kf6/kdesu

and got the kdesu usage info, so it's there and runnable.

I added the directory to my path in the file:

/home/username-f16/.profile

by adding this line:

PATH="$PATH:/usr/lib/x86_64-linux-gnu/libexec/kf6"

I then closed and reopened Krusader. When I attempted to start root mode, the same error came up.

Can someone help? I don't know what to do.
