pfSense

In previous versions, when upgrading, the activity textbox displays what's happening. At the end it said something like "all done, rebooting".

When I upgraded to 2.4 it didn't. The text box content was as below. There was no sign that downloads had completed since the last message was "[22/234] [23/234] Fetching smartmontools-6.5_2.txz: .......... done". At that point nothing else displayed and it appeared that upgrade had frozen or failed, or something was wrong.

Probably not how it should be.

This was the content of the upgrade GUI text area:
