Ubuntu – How to logout of Ubuntu Software Center? (Seriously, where’s the logout button?)

I have not actually tested this, but I think it should work in theory.

1. Open the Ubuntu Software Center application.

2. Click on the File menu and click on Reinstall Previous Purchases.

3. Logon with your original account and you setup and you should be able to install the original applications that you purchased.

You can use one-conf to sync between two or more computers.

To use one-conf, login into your Ubuntu One account on all the computers that you want to sync. Then, open software center and click on 'File' menu. And then, click the option 'Sync Between Computers...'

After you click that, a sidebar would appear on the left side. It will only list the local computer.

On the bottom, there is a button, clicking which would display a dialog box reading Start syncing <system-name>. Click the button and your computers would then be synced between them. Only after clicking the button would the computers associated with the Ubuntu One account would be displayed on both the computers.
