update failed

Tried to update my Fedora 29 this morning. It failed

with this error:

[SKIPPED] google-chrome-stable-72.0.3626.119-1.x86_64.rpm: Already

The downloaded packages were saved in cache until the next successful

You can remove cached packages by executing 'dnf clean packages'.
Error: GPG check FAILED

Is there a work around or should I just wait ?

Thanks
