Sdkmanager 1.8.0 GUI not showing up on ubuntu 18.04

After installing sdkmanager_1.8.0-10363_amd64.deb on my ubuntu 18.04, I run sdkmanager but no GUI shows up.
Since I could not find any log message, I have no idea to fix the issue.
I could successfully run GUI at least with sdkmanager 1.7.1-8928

$ sdkmanager
Gtk-Message: 02:08:50.725: Failed to load module "canberra-gtk-module"
Gtk-Message: 02:08:50.726: Failed to load module "canberra-gtk-module"

sdkmanager CLI also failed with the error like below:

$ sdkmanager --cli install  --downloadfolder ~/Downloads/nvidia/sdkm_downloads/ --checkforupdates false --datacollection disable --license accept --product Jetson --version 4.6.2 --targetos Linux --target JETSON_AGX_XAVIER --flash all --exitonfinish

Hi, y.furuta,

Do you have this package installed on your machine? What’s the output of dpkg -l | grep canberra-gtk-module command in terminal window?

For CLI issue, can you please package and attach ~/.nvsdkm folder which contains the full log for investigation?
