Version Update Error Message in Status:Dashboard | System Information | Version

[tweek]

This morning I started getting the following warnings in the System Information/Version widget of the Dashboard at the point the widget is attempting to check if the firewall is running the most current version of pfSense:

Unable to check for updates.

Can anyone clue me in as to what is happening here?  I'm not sure what's up. I ran fsck in single user mode and it says the drive is fine and I've used df -h to confirm I have plenty of free space available.

An update…I rebooted the firewall, then brought up a different browser (Internet Explorer 8.0), navigated to the dashboard...and the System Information widget works properly:

2.0-RELEASE (i386)
built on Tue Sep 13 17:28:43 EDT 2011

You are on the latest version.

I then cleared out my Firefox cache and did a page reload. Problem solved.  Not sure why Firefox was caching the text after a full page refresh, but it was.  Grrr….

I just observed the same issue, also with Firefox. Clearing the cache solved it.

Some browsers can be pretty bad about caching those things. The initial error indicated your /tmp slice was full. If it was on NanoBSD that's not terribly hard to do since it's a RAM disk.
