Could not acquire hardware ID

Hi,
When I try to launch the example_datasets, I receive the error, "
Launched job oMvWKdKRSJAR2yETn
Could not acquire hardware ID.
"
I guess the path of the installation is wrong, but I can’t solve it.
The following is the error,

Hi,

Which OS are you running cryoSPARC on? Please ensure ifconfig is installed:

which ifconfig
ifconfig

If it isn’t installed, please install it and then restart cryoSPARC:
cryosparc stop
cryosparc start

Thanks for your replying.
The cryosparc is installed in Ubuntu 16.04 and the ifconfig is installed. But the problem is still unsolved.

Can you run ifconfig on your machine and report the output (you may want to remove any IP addresses)
