spacebar preview doesn't work in default Ubuntu

[tom]

https://help.ubuntu.com/stable/ubuntu-help/files-preview.html

Supposedly, a preview should happen when you press space in nautilus with a file highlighted.

Instead, nothing happens.

Workaround: install gnome-sushi

[Sebastien Bacher (seb128)]

That requires gnome-sushi to be installed which we don't do by default

[tom (tombuntus)]

@seb128 I actually had gnome-sushi installed, and still nothing.

Might wanna revise https://help.ubuntu.com/stable/ubuntu-help/files-preview.html to not imply Ubuntu 16.10 does previews unless someone installs gnome-sushi. That article certainly makes it sound like previewing files is part of 16.10.

"The built-in preview supports most file formats for documents, images, video, and audio. In the preview, you can scroll through your documents or seek through your video and audio."

The words "built-in preview" mean that, at least according to this official Ubuntu documentation, users DON'T have to install any extra packages to get preview.

For me, in 16.10, gnome-sushi does nothing either. Only thing that works is gloobus-preview, which as I understand is some sort of derivative of sushi. Gloobus sucks pretty bad. Doesn't let you press arrow keys from file to file. You have to press space twice, then arrow to the next file, then space again, then space again to close preview, then arrow to the next file. Pretty sucky.

Please add functional preview to default Nautilus, as ubuntu.com/stable promises, or don't promise it as a "built-in" function.

after testing I found it is not nothing happened, but sushi-start crashed!

[Sebastien Bacher (seb128)]

it's a gnome-sushi issue then, reassigning

[FanJun Kong - ( BH1SCW ) (fjkong)]

also reported to upstream
https://bugzilla.gnome.org/show_bug.cgi?id=777646

[FanJun Kong - ( BH1SCW ) (fjkong)]

seems like duplicate bug to
https://bugs.launchpad.net/ubuntu/+source/gnome-sushi/+bug/1644781

[FanJun Kong - ( BH1SCW ) (fjkong)]

fixed after apt-get install gir1.2-evince-3.0

[FanJun Kong - ( BH1SCW ) (fjkong)]

fixed in Debian #842319

[tom (tombuntus)]

When will we get the Debian fix? I'm suffering the same problem with sushi-start crashes in 17.04 Unity and GNOME

[Jeremy Bícha (jbicha)]

tom, please file a new bug by running this command:

ubuntu-bug gnome-sushi

[tom (tombuntus)]

I can't find what package to call it to update for Bionic. This bug has remained throughout 17.04, 17.10, and 18.04.

https://help.ubuntu.com/stable/ubuntu-help/files-preview.html still says it's built-in. It's still not. A fix was never released. A fix is either stop promising functionality on the official documentation, or make preview function from scratch in default install of Ubuntu.

[Jeremy Bícha (jbicha)]

Ok, I'm reassigning to the Ubuntu documentation then.

[Gunnar Hjalmarsson (gunnarhj)]

Hopefully this can be fixed upstream with a conditional note about installing gnome-sushi. I have submitted a GNOME bug with a patch.

[Launchpad Janitor (janitor)]

This bug was fixed in the package gnome-user-docs - 3.28.0-0ubuntu1

---------------
gnome-user-docs (3.28.0-0ubuntu1) bionic; urgency=medium

  * New upstream release (LP: #1656071)
  * debian/rules:
    - New Korean translation of system-admin-guide
