I am not able to run gcloud commands on lubuntu

I Installed gcloud SDK on lubuntu-32bit system, but while running gcloud commands its giving error.

ERROR

ERROR: gcloud crashed (OperationalError): database is locked

If you would like to report this issue, please run the following command:
  gcloud feedback

To check gcloud for common problems, please run the following command:
  gcloud info --run-diagnostics

re-installed again but not able to figure out it.

Solution

The error suggests that something is keeping gcloud's database open. This can be caused by numerous reasons, some possibilities and recommendations are:

Make sure you’re not running multiple ‘gcloud’ commands in parallel, as this is currently not supported and there’s a Feature Request already open for that here.
Avoid installing the Cloud SDK or storing the credentials on an NFS. If you have, install the Cloud SDK in a local directory or respectively, store the credentials in a local disk by setting the environment variable CLOUDSDK_CONFIG to a local disk location, i.e if you’re using bash:

export CLOUDSDK_CONFIG=/some/local/path/.gcloudconfig
Lastly, double check that you're using the latest version of the Cloud SDK by running gcloud components update (although I assume you are). Alternatively, you can run gcloud components reinstall to attempt in fixing a corrupted Cloud SDK installation, which is known to have helped others in the past.
