Ronnie Tucker (ronnietucker) wrote :

Same here. On upgrading from 15.10 to the 16.04 b2 the Gnome Software app shows a shopping bag icon and 'No Application Data Found' on the All tab. Installed tab shows nothing. Blank screen. And the Updates tab shows a check icon and 'Software is up to date'.

Clicking the menu in Software shows a vertical bar with no text items.

Can attach screens if required.

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

Tried your idea #3 and no difference. Still the Software application with nothing on offer or listed as installed.

Matthias Klumpp (ximion) wrote :

Did you run `sudo apt update` after the installation?
Is the appstream package installed?

Tried #3 and #5 but it didn't help.

I attached the output 'gnome-software' prints when started. I think these bugs are related:

There's an Ask Ubuntu question about this bug.

The accepted answer did not solve the problem for me, but it might help someone else.

Hmm, this is a really odd bug, the l10n settings should have zero influence on this.
Can you please run `sudo appstreamcli refresh --force --verbose` and `appstreamcli status` and paste the output somewhere?

This is not really critical: It only affects a few users, does not cause data loss, and has an easy workaround.
Would still be useful to find out why this happens...
@tartley: Did you run `apt update` previously, without gnome-software showing apps? Do you maybe have repositories which are inadequately signed installed (e.g. Google Talk)?

Okay, this looks good.
Can you please run `killall gnome-software ; gnome-software --verbose` in a Terminal and attach the full output you see to this bugreport as textfile, or paste it somewhere (e.g. paste.debian.net)?

Ronnie Tucker (ronnietucker) wrote :

This is the output from the killall command.

Unfortunately the top of the output is a bit chopped. There was so much text I could only scroll back to what you see here.

Matthias Klumpp (ximion) wrote :

Hmm, the head of the output would have been more interesting...
But anyway, it looks like you have a `/var/cache/app-info/yaml/xenial-main_amd64.yml.gz` file - any idea where that came from?
Can you run:
```
rm -r /var/cache/app-info
sudo appstreamcli refresh --force --verbose
```
To clean that up, and also attach the output of the refresh command?

Okay, that looks okay-ish (it's weird that there are ID collisions for firefox.desktop and other stuff, that shouldn't happen...).

If the issue isn't fixed, the full log of GS would help. You can store it in /tmp via:
`killall gnome-software ; gnome-software --verbose | tee /tmp/gnome-software.log`

Ronnie Tucker (ronnietucker) wrote :

I think that's it fixed! I can see items and categories. Which is more than I could see last time!

Thank you!

Matthias Klumpp (ximion) wrote :

So, this issue was basically misconfiguration and interference of bad AppStream metadata...
I need to think about this a bit more, maybe I can come up with something to fix these issues automatically...
(Although reliably removing cruft metadata will be difficult - ideally, that data shouldn't have been introduced)

Anthony S (aaaantoine) wrote :

The command in #21 fixed the issue for me.

While I agree `rm -r $x` is the obvious solution, I didn't know what $x was supposed to be and this was the first mention I saw of it.

Joel (joel-kuntz-92) wrote :

Here is the list of things I've tried (in order, not sure if the order made a difference in fixing)

- changing language and restarting (didn't work)

- sudo apt purge gnome-software ubuntu-software
    sudo apt autoremove
    sudo apt install gnome-software ubuntu-software (didn't work)

- sudo appstreamcli refresh --force --verbose (didn't work)

- sudo rm -r /var/cache/app-info && sudo appstreamcli refresh --force --verbose (didn't work)

- killall gnome-software ; gnome-software --verbose | tee /tmp/gnome-software.log (then ctrl-c and it worked)

I'm assuming some combination of this fixed it. Hopefully this helps in finding the correct solution

Jeromie Rand (jeromie) wrote :

None of the above worked for me. Instead, there were several plugins that gave the following error:

Failed to parse /usr/share/app-info/xmls/org.freedesktop.fwupd.xml file: cannot process file of type application/x-go+xml

I later got a similar error at /var/cache/app-info/xmls/fwupd.xml

For the time being, I removed the fwupd.xml files (after making a backup) and all works fine again. When I check the mimetype it shows application/xml; I'm not sure where the application/x-go+xml is coming from.

Jeromie Rand (jeromie) wrote :

I tracked my problem down to a bad entry in /usr/local/share/mime/globs (and /usr/local/share/mime/globs2). The application go-gui had registered files of type *.xml to x-go+xml.

Additional info re: my comment above. I have Ubuntu 16.04 running on two PCs, an Asus laptop and HP desktop. On 7/7 both were having this issue but since then the laptop somehow self corrected after applying updates a couple of days later. The desktop is still not working but all updates have been run.

Side note: I discovered that if I run command sudo gnome-software from terminal, Software Center opens with all applications showing normally. Is that a viable workaround? I'm reluctant to try installing applications that way because I don't want to have to run them as root. Any thoughts?

I've been watching the "Ubuntu-Software" since I fresh installed 16.04 on another machine.
My complaint was the same; offerings meager.
Now after an upgrade on machine #2 the same software tool appeared.

 Then I tried "Ubuntu Software Center 15.12" and it is the full meal deal. All that I expected albeit in a different GUI form from the 14.04 that I was used to.
select " ubuntu Software Center" from Unity search your computer button and I locked it to the unity launcher. It was there with a different name all ready to go
Works for me.

I've read all the suggestion, but I found my quick solution is by "changing my update server to the original main server", and then it solved my problem with "Ubuntu software center, no application data found" (I've changed my update server last time to singapore based "nus" due to suggestion by my network administrator to enhanced update speed)

Just changed 'software and updates' to download from the main server. After reboot Ubuntu Software is finally displaying packages correctly. Thanks to hendi for the suggestion!!!

`sudo appstreamcli refresh --force --verbose` and `appstreamcli status` worked for me.
