Ubuntu Software does not show all available software

[ryukun]

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

$ lsb_release -rd
Description: Ubuntu 16.10
Release: 16.10

main, universe, restricted and multiverse repositories are enabled.

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

$ apt-cache policy software-center
software-center:
  Installed: (none)
  Candidate: 16.01+16.04.20160420
  Version table:
     16.01+16.04.20160420 500
        500 http://tr.archive.ubuntu.com/ubuntu yakkety/universe amd64 Packages
        500 http://tr.archive.ubuntu.com/ubuntu yakkety/universe i386 Packages

3) What you expected to happen

It is expected that when I search for a software by using Ubuntu Software (a.k.a. Ubuntu Software Center) it is listed as available if it is available by using apt command.

4) What happened instead

Ubuntu Software (a.k.a. Ubuntu Software Center) does not show all software which are in fact available by using apt. For example: keepassx, keepass2, freeciv, arbtt, qtcreator...

Thank you for taking the time to report this bug and help make Ubuntu better!

The default Software app starting in Ubuntu 16.04 is gnome-software (or ubuntu-software).

It would be more useful if you would file an individual bug for each app that should show in the Software app but isn't. If you do this, please add the tag appstream to each bug, so that someone who wants to work on this type of issue can easily find these bugs.

I'm closing this bug since this isn't fixable in gnome-software itself.
