NO webcamoid in Ubuntu Software in Zesty 17.04

I suggest you report a bug. Zesty is not ready and not stable

I don't know if I should open the bug against webcamoid or against Ubuntu Software.
The problem seems because in Ubuntu Xenial webcamoid has appstream metadata while in Ubuntu Zesty (and also Wily) the metadata are missing.

in Ubuntu Xenial:

corrado@corrado-xeni-prova:~$ uname -a
Linux corrado-xeni-prova 4.4.0-71-generic #92-Ubuntu SMP Fri Mar 24 12:59:01 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
corrado@corrado-xeni-prova:~$ appstreamcli s webcamoid
Identifier: webcamoid.desktop [desktop-application]
Name: Webcamoid

in Ubuntu Zesty:

corrado@corrado-z-beta3:~$ uname -a
Linux corrado-z-beta3 4.10.0-15-generic #17-Ubuntu SMP Fri Mar 24 17:51:38 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

It's in Zesty.

It's in the universe repository. Do you have that enabled.

May be I was not clear. I had no problem installing webcamoid on Ubuntu Zesty using Synaptic (and it works well) but the problem I want to point out is that webcamoid is ignored by Ubuntu Software and can't be installed using Ubuntu Software because it lacks appstream metadata.
I don't know if appstream metadata should be added/created by webcamoid developers or from ubuntu team.
