The new Ubuntu Software Center does not display all software. For example no third party repo applications are displayed.

Search for example:

Ubuntu-restricted-extras - no results
muon - no results
krita - no results
samba - no results

These do not show under installed either, though they are installed.

However, all are shown in Synaptic Package Manager and MUON

Additional:

I have installed the old Ubuntu Software Center and can confirm that ALL applications are correctly listed.

Status changed to 'Confirmed' because the bug affects multiple users.

[Sebastien Bacher (seb128)]

Thank you for your bug report but gnome-software is meant to list graphical softwares only, technical items like samba are for more technical users and can be installed from the command line or synaptic

[pst007x (turone)]

Changed in gnome-software (Ubuntu):
importance: Undecided → Low
status: Confirmed → Invalid

So @Sebastien Bacher (seb128) the old Ubuntu Software Center all applications were shown. However the new Ubuntu Software Center does not index all applications, not even installed applications....

So are we saying that this is normal? And confirming that it is useless to use as a Software Manager?

So apps like Krita are considered technical?

If Seb128 is right then the Ubuntu Software Center is as useless as ever.

[Sebastien Bacher (seb128)]

Your report describe several issues, it's normal that samba or ubuntu-retricted-extras are not listed. Krita being missing is a bug in calligra and doesn't only impact gnome-software, see bug #1576827 , muon is likely in a similar situation

[Sebastien Bacher (seb128)]

Oh, also, to maintain a respectful atmosphere, please follow the code of conduct - http://www.ubuntu.com/project/about-ubuntu/conduct. Bug reports are handled by humans, the majority of whom are volunteers, so please bear this in mind.

Sebastien.. fair comment... I apologise if I sounded rude, that was not my intent.

In my experience with respect to Muon and the old software-center apps like Samba, Krita, etc and all installed application all showed up when searched for.

I am confused as to why it is now considered normal that in the new Software-Center not all installed apps should be listed.

Is it correct that not all installed apps are now listed, as well as all available applications?

Is the new Software-Center no longer considered an application manager but rather just a limited store?

If so this is a disappointing move in my opinion, when applications like MUON work as expected.

Thanks

With Muon, Sebastien actually meant Discover, which has the same problems like GNOME Software.

GUI applications should still be visible, and the fact that some are not shown is a bug in the metadata generator or (more likely) the packaging or upstream software.
Not all of these issues were addressed before the release, due to not enough manpower and probably not enough people caring about it.
See http://mhall119.com/2016/03/help-make-gnome-software-beautiful/ for how to report issues and fix things properly.
This should be sorted out for Yakkety, and some issues can also be fixed by stable-release-updates, e.g. the Krita thing would be a pretty good candidate, since it is highly likely a packaging bug.

[pst007x (turone)]

So, this is not normal and is a bug.... however, this is not the place to report this bug?

"not enough people caring about it." so what you are saying that using this as a package manager is not high on the list of importance.

It is just strange that if the fault was with the packages then why are ALL applications listed in Synaptic and MUON?

Anyway clearly no one seems that worried that it is currently broken.... so best to not use it and stick to alternatives.... No probs... Thanks

[Matthias Klumpp (ximion)]

Synaptic and Muon look at packages, which is something different than applications.
Applications and software with much metadata is in a different file. We generate the data from packages, but it is not the same as a package. In order to get enough metadata out, the packages must match some criteria, and meeting those is the job of the individual package maintainers.
So, your bug against gnome-software is actually a bug against Krita, bug #1576827 in particular.

Since samba is a technical thing, it will likely never be shown in a tool like GNOME Software, instead it will be installed in an app actually wants it.

3rd-party repos not being able to display apps is another, different bug, bug#1576780

So, yeah, that's the whole story. Maybe this issue can be closed in GS as invalid.

The "nobody cared enough" statement was basically me being frustrated with not enough people caring to fix their metadata, something which will improve in future, fortunately.
(We will also have more visible diagnostic messages in Debian soon, which should help fixing this issue. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=806740 )

[pst007x (turone)]

Ok, thanks for the info.

Samba, for example, did appear in the old Ubuntu Software Center.... so to understand you the METADATA info hasn't been updated to work with the new Software Center in ubuntu...

So this includes already installed software too....

Ok thanks for helping me to understand...

[Matthias Klumpp (ximion)]

Yeah, the old Ubuntu Software Center was designed to also replace Synaptic, while the new GNOME Software is for applications / fonts / other visible stuff only (the same as KDE Discover does).
Advanced users are encouraged to use Synaptic, Muon or the command-line directly.

[Fusion (bornolbers)]

It's not only third party apps that isn't showing.. The most apps I used and installed from old ubuntu-software-center doesn't exist in the "gnome-new-one"... I can list more than 50 "simple" (not for advanced users Matthias mentioned) apps that exists in the old one, installed normally on ubuntu 16.04 and didn't and don't exist on the new one. I also did a clean install, but problem remains. It is like the new software center reads a different repository than synaptic, apt, apt-get and old software center..

It isn't an "opinion".. I also use old one or synaptic as a solution... but it is a problem!
