Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have three laptops, all running 12.04 (they were running 11.10). I have backups working to Ubuntu One for my primary laptop, and folder synchronization of my Documents, Pictures and Music folders working to all three laptops. I like the idea of being able to work on a document on my primary laptop, head out with a netbook and do some quick work on the same document, then finish it up on the third and not worry whether I grab a netbook, a low-end laptop or the bigger, heavier one.

I'd like to keep applications synchronized across all three laptops. I saw where you can do that using the Ubuntu Software Center, then click Installed, File and Synch between Computers. When I do that - I don't see my three laptops listed. When I log in to Ubuntu One - I see all three laptops. I can synch my folders just fine. Not sure how to synch my apps.

Its very easy.

  1. Go to the Software Center and and see the option of SYNC BETWEEN COMPUTERS option under the file menu.

  2. As you click on it you will see your computer registered and a list of all apps on your computer

  3. When you will install fresh,that computer will be considered a new computer.

  4. You just have to sign in in your ubuntu account and your previous computer will be shown.

  5. Click on it,you'll get a list of all apps.Select install on the app you want to install.

PS:For this you need a "SINGLE SIGN ON UBUNTU ACCOUNT"(b4 reinstalling create it so that your pc is syncd)

I've done your above 5 steps, but when I click on the other computer (step 5), it presents me with an empty list, regardless of whether or not the two computers have the same installations or not. Any idea what might be (not) happening? –  Ryan Budney May 23 '12 at 9:01
    
On Ubuntu Forums someone else is having essentially the same problem: ubuntuforums.org/showthread.php?t=1969664 –  Ryan Budney May 23 '12 at 9:11
    
you signed in on all 3 computers?? if yes then check on all 3 computers,what is the last sync time...under the list you will see it...is it sometime recently?? –  Nirmik May 23 '12 at 9:28
    
Yes, the sync time is listed as just a couple minutes ago on all computers. –  Ryan Budney May 23 '12 at 19:07
    
Then try loging out of your ubuntu account from all 3 computers and then log in again –  Nirmik May 23 '12 at 19:10
