Rpm-ostree status error 99

Hello,
I just installed Silverblue Fedora 30 OS as a HVM in Qubes. When I typed in rpm-ostree status, I get the following error:
Warning: failed to query journal: Cannot assign requested address (os error 99)
I also got the same warning when I installed Silverblue Fedora 30 as a Virtualbox guest in Windows 10.
Thanks in advance.
Jeff

Did you try doing an rpm-ostree update?

This looks like "Warning: failed to query journal..." doing `rpm-ostree status` as unpriv user · Issue #1729 · coreos/rpm-ostree · GitHub

Thanks all.
The error message was a user permission issue. I was able to get around this warning by executing the command as root.
