Cannot install microstack, says modprobe operation not permitted

Ubuntu MATE 20.04LTS on GPD Pocket 2 Intel Core-3 7y30 8GB mem

I try to install microstack on my Ubuntu but once succeed but once remove it and reinstall microstack I cannot install says ’

snap install microstack --beta

error: cannot perform the following tasks:

  • Start snap “microstack” (216) services ([start snap.microstack.load-modules.service] failed with exit status 1: Job for snap.microstack.load-modules.service failed because the control process exited with error code.

See “systemctl status snap.microstack.load-modules.service” and “journalctl -xe” for details.

here is the result of systemctl, I really wondering why modprobe doesn’t permit from microstack installer control …

I reinstall snap/kmod(modprobe) the situation is not changed - the same error has occurred, thus I cannot install.

If any ideas please let me know.

Same here…I’m using ubuntu 18.04 cloud image.
How to fix this problem?
