I opened another tab in the browser and checked the pfSense GUI, and it still showed the old version. As per the release announcement, run the following command to refresh repository configuration:
pkg-static clean -ay; pkg-static install -fy pkg pfSense-repo pfSense-upgrade
and attempt an upgrade again. The second attempt has been reported to be successful most of the times. The issue is logged as a bug already.
Note: As always, before upgrade, take a backup of your configuration. Also, in case you are running pfSense in a virtual environment, take a snapshot before upgrade so that you can easily revert in case something happens that cannot be fixed.
