ptiagent-arm64 must be run as root!

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.
 
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. -
