ptiagent-arm64 must be run as root!

MacBook Air M4
macOS 26.2
Parallels Desktop 26.2.2 (57373)

Installed Debian 13 ARM version with KDE desktoop environment

Installed Parallel Tools by copying the installer from the mounted CD to a folder in my home directory ~/Downloads/parallel_tools

Ran the following command: sudo apt-get install -y dkms libelf-dev linux-headers-$(uname -r) build-essential

Then did: sudo ./install

The installer stated that it finished successfully.

I rebooted and each time I log in, I get a dialog saying: /usr/lib/parallels-tools/installer/ptiagent-arm64 must be run as root!

I changed my desktop session from Wayland to X11. Still get the dialog.

Can NOT find any posts or articles by searching with DuckDuckGo or Google regarding this error.

 

Same, but everything is working as it should, so idk

 

I have the exact same issue.

 

I am having the same issue as well.
@Zemiak How are you sure that it is working as it should?

 

I faced a similar issue with Parallels Tools on Debian ARM KDE. It looks like the ptiagent-arm64 process is trying to start without proper root permissions during the desktop session login.

You can try these fixes:

1. Remove and reinstall Parallels Tools completely:
   

sudo /usr/lib/parallels-tools/install --remove
sudo reboot

Then reinstall:

sudo apt-get install -y dkms libelf-dev linux-headers-$(uname -r) build-essential
sudo ./install

1. Check ownership and permissions:
   

ls -l /usr/lib/parallels-tools/installer/ptiagent-arm64

1. Try running manually as root:
   

sudo /usr/lib/parallels-tools/installer/ptiagent-arm64

1. KDE Wayland on Debian ARM sometimes has compatibility issues with Parallels Tools. Some users reported fewer issues using a lighter desktop like XFCE.
   
   
2. Also check if an autostart entry is launching the binary incorrectly:
   

~/.config/autostart/

or

/etc/xdg/autostart/

There may be a broken desktop entry calling ptiagent-arm64 without sudo/root privileges.

Hopefully Parallels releases a fix soon for Debian 13 ARM compatibility. -
