The new software center in Ubuntu 16.04 shows no application data found

Question

This is the error I get when I open the software center. I've tried rebooting and running sudo apt-get update but I see no improvement. It worked earlier but I don't know what went wrong since then. I'm using Ubuntu 16.04 final release on a Dell Inspiron 15R. Any advice will be appreciated. Thanks in advance.

EDIT: The problem magically solved itself without me doing anything special (or maybe inadvertently doing something, I don't know). So I'd still like to get to the root of this.

Solution 1

Just had this problem after using bleachbit to cleanup the system on moving from the beta to the official release. Cleaning out all the cache data also blanked out the software center (re:user533424 above).

It seems to "magically" reappear by anything that regenerates this data. So...

settings>region languages> ... and changing or reinstalling your current language

....also worked for me.

Solution 2

Happenes after you used BleachBit with root access and cleaned App cache Data

1. Open Ubuntu Software Center
2. Click on updates tab
3. Click on small refresh button located at the top-left corner
4. Wait for it

Refer pic for refresh button

Everything will be back to normal

Solution 3

I think this has to do with the /var/cache directory, at least that is what I suspect based on my own experience.

Workaround that worked for me:

sudo apt purge gnome-software ubuntu-software
sudo apt autoremove
sudo apt install gnome-software ubuntu-software

Solution 4

It works for me. Change Language Support > Regional Formats to English(United States), then reboot your computer. Software center works properly now.

Solution 5

I had the same problem. But my problem was not rooted in language setting or anything related to that. My problem was cuased by a program called GoGui; a game of go interface program that can connect to different engines. I found solution to my problem through launchapad post: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1563155 #28 and #29. So basically the problem was the gogui registers file types of *.xml to x-go+xml which I guess Ubuntu Software tries to open with but can not be found. Deleting /var/cache/app-info/xmls/fwupd.xml and unregistering the the created lines by Gogui in /usr/local/share/mime/globs and /usr/local/share/mime/globs2 solved the problem for me!

Oh btw. did you try to refresh via the "Updates" tab on the very left side the little refresh button? It worked for me...

[Engin SENEL]

I tried doing that, but I didn't see immediate results. I checked back after a couple restarts and it works now. Weird.

[Engin SENEL]

So you just reinstalled it?

[Engin SENEL]

Makes sense because I had also used bleachbit.

[Jonathan Hartley]

Language support is in System Settings.

[Jonathan Hartley]

I haven't used bleachbit, and this solution doesn't work for me.

Although this might help, it can not be the ultimate solution to change the whole system's locale just to be able to install software through a graphical user interface... I appreciate your answer, it's just that I'm disappointed of the Gnome Devs if this actually solves the problem.

[leetNightshade]

This works like a charm! Don't have to restart or remove/install anything. This is the best option.

[Abdul Rehman]

+1 this people, its the only logical best way to make it work.

I don't have this icon

Starting Ubuntu Software on 16.04 cause an 'internal error'. Reinstalling it totally fixed it. It upgraded some packages which I presume were the cause of the problem.

[DrMoishe Pippik]

Other fixes did not work on my new Ubuntu 16.04 LTS installation, but the expedient of reinstalling did! kudos

[Zibri]

I have the icon, I did it and nothing changed.
