PermissionError: [Errno 13] Permission denied: '/sys/kernel/config/device-tree/overlays/pynq/dtbo'

Environment:

• Kria KR260
• Ubuntu 22.04 Desktop

I installed PYNQ DPU according to instructions in Section 3 "Install PYNQ DPU" of this tutorial with board changed to KR260 in line 38 of install_update_kr260_to_vitisai35.sh. But after reboot and login, I got the following errors:

Traceback (most recent call last):
  File "/usr/local/share/pynq-venv/pynq-dts/insert_dtbo.py", line 30, in <module>
    db.insert()

    mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: '/sys/kernel/config/device-tree/overlays/pynq'

What is the matter and how to fix it?

Due to the long size, terminal log of the installation is saved in a file and attached below.
