Another process using packaging system database in Adept Manager

I was upgrading Kubuntu today, when it told me something went wrong and so I stopped it. Then, when I went back to restart Adept Manager, I got the message:

Another process using packaging system database

I started looking around my running processes and attempting to kill whatever I thought might be causing the problem, but it wasn’t working. So, I followed my mantra: “When all else fails, reboot!” and did what no Linux person will ever admit doing. I rebooted the system.

To my chagrin, the error was still coming up, even after a Linux reboot. ;(

Then I learned of this command:

sudo dpkg --configure -a

which causes things to continue where they left off in the upgrade and I was back in business! No GUI this time, but at least I could get my stuff back up and running properly.
