After installing 16.04, Ubuntu Software is always empty as shown in the screenshot. How can I fix this?

Change the Download from server in Software & Updates. I had mine set on to a nearby Swedish one (which maybe itself has not updated yet). I changed to a more official looking UK server and Ubuntu software is now working.

  • Note they are all "official". However, there could be issues with the servers, yes. – Tim Apr 24 '16 at 14:30

This is most likely because newly installed systems lack a database of available packages. You can generate a recent one from the package repositories with the below steps.

  1. Open a terminal. There are many ways to achieve that but the most common are to

    • type terminal in the dash and start the application of the same name or
    • press Ctrl+Alt+T.
  2. Type or copy & paste the following commands into the terminal an run them:

    sudo apt update
    sudo apt upgrade -y
    

    (If you run into any errors in the process, please open a new question and include the entire output of these commands verbatim.)

  3. Re-open Software Center and try again.

  • You also possibly might want to check your sources. It's possible to do this in a GUI-way ("Software and Updates" launcher), but I recommend doing it in command line if you're already having issues with Ubuntu Software. – Hee Jin Apr 9 '18 at 20:17

If sudo apt-get update && sudo apt-get upgrade followed by a restart doesn't fix the issue, I would suggest:

sudo apt-get dist-upgrade

Restart. If that doesn't help, you could also try backing up then deleting a folder in your home directory associated with the program. First, in Terminal or other CLI:

killall gnome-software

Then

mv ~/.local/share/gnome-software{,-BAK}

Reopen Ubuntu Software. (If needed, you can always undo the removal of the gnome-software folder and restore the backup: rm -r ~/.local/share/gnome-software && mv ~/.local/share/gnome-software{-BAK,})

Finally, if none of this works for you, I would be interested to know the output of:

find /etc/apt/ -name '*.list' -ls -exec cat {} \;

This is a list of all your allowed sources (sources are the repositories that contain the available software to download).

Although I can't think of any reason why you'd have nothing in sources.list, it's also the only explanation I can think of as to why nothing shows up as available in Ubuntu Software after trying all the normal troubleshooting steps.

Example output of the above command:

  1234567      4 -rw-r--r--   1 root     root         3026 Apr  8 22:39 /etc/apt/sources.list

In the above example, the four main repositories are enabled.

  1. Main - Canonical-supported free and open-source software.
  2. Universe - Community-maintained free and open-source software.
  3. Restricted - Proprietary drivers for devices.
  4. Multiverse - Software restricted by copyright or legal issues.

Updates are also enabled. Repos with software from Canonical partners are not enabled. These represent the standard options that are enabled when you install Ubuntu for the first time.

If you had added any PPA's they would also appear in the output above.

  • Renaming the gnome-software folder did it for me. Thanks. mv ~/.local/share/gnome-software{,-BAK} no idea why. – James Newton Jan 28 '19 at 22:00

If the above doesn't work try to re-install Gnome-software, that worked for me

sudo apt autoremove gnome-software && sudo apt install gnome-software
