Installing packages in background after live upgrade?
Just did a live upgrade from 2.0.3 to 2.1.0 and all seems to have gone well except every page in the webGUI has a big red box at the top warning not to make any changes since packages are being upgraded in the background. Problem is this warning has been showing over 30 minutes and pfSense doesn't actually seem to be installing anything.
How long should this take?
It can take much longer than you think. At least much longer than I expected. ;) 2.1 is using self contained pbi files that contain all the package dependencies and as such are much larger than in 2.0.3. If you have a slow connection or slow flash media this can take some time.
If it really has become stuck you can use the 'Clear package lock' button in Diagnostics: Backup/Restore:
You should check the logs if you do use that to make sure the packages installed correctly.
