Cannot associate .sb2 file to scratch2.0 offline editor on Linux Ubuntu

I want to open scratch 2.0 offline editor by clicking .sb2 file, but now files are opened as a zip file.
If I launch scratch 2.0 offline editor first, then I can open .sb2 file through menu.

I installed Edubuntu 14.04.4 LTS to both 64bit PC and 32bit PC which both are installed scratch 2.0 offline editor but cannot open it from .sb2 file.

I have tried ways below already

1. from properties of .sb2 file.
-right click the file and choose properties
-select “Open With” tab
-cannot find Scratch 2.0 in Other Applications list

2. use Ubuntu-Tweak's file type manager
-install ubuntu-tweak_0.8.8-1
-launch Ubuntu Tweak
-select “Admins” tab
-choose “File Type Manager” under System
-choose Application Categories
-select “Zip archive (which is now .sb2 file's Type on properties)
-click Edit button
-click Add button
-”Use a custom command"
-Browse and select Scratch 2 in opt/Scratch 2/bin folder
-click open button
-no reaction for Add button or Cancel button

3.command
-open default.list by text editor
-change the line as below
application/zip=file-roller.desktop -> application/zip=Scratch\ 2.desktop

-open mimeapps.list
-change the line as below
application/zip=file-roller.desktop -> application/zip=Scratch\ 2.desktop

Could anyone help or see the same state?

Cannot associate .sb2 file to scratch2.0 offline editor on Linux Ubuntu

Here is a list of steps:
  1. open the offline editor
  2. select “Open” on the file menu
  3. choose the .sb2 file
If that doesn't work:
  1. get Windows
  2. that's it (no offense, but it's bound to work on that)

i have almost 2000 forum posts how sad

Dear IgDegOo,

Thank you very much for the reply.
I can open .sb2 file by the way you mentioned. But I want to have second grade students in primary school play games on scratch to improve their calculation skill, so easier way is preferable that only double click a .sb2 file to open it.
There is a reason I want to use linux. I will distribute second-hand PCs to primary schools in rural area so using windows would urge me to pay a lot of cost…

>iamjmm
Yes, I've found the solution.
Try this way below please (which is in my environment).

1. define .sb2 file's type
sudo vi /usr/share/mime/package/***.xml
*** is new file's name. Set is as you like. ex)scratch2
write text below in the file

<?xml version=“1.0” encoding=“UTF-8”?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info“>
<mime-type type=”application/x-scratch2“>
<comment></comment>
<glob pattern=”*.sb2“/>
</mime-type>
</mime-info>

2. associate .sb2 file with scratch 2 application
Find ”edu.media.mit.scratch2editor.desktop" file under directory of /usr/share/applications/ ,
and add only one line in the last line of that desktop file.
MimeType=application/x-scratch2

3. update
sudo update-desktop-databese
sudo update-mime-database

4. reboot PC

3. update

sudo update-mime-database

4. reboot PC

Thank you for your guide! This problem bothered me for a long time. Since I am almost illiterate in these matters and I mainly copypasted your solution, here's a few typos that caused me minor difficulties in the copypasting process:

- “/usr/share/mime/package/” should be “/usr/share/mime/packages/”;
- “sudo update-desktop-databese” should be “sudo update-desktop-database”;
- “sudo update-mime-database” should be “sudo update-mime-database /usr/share/mime”

Cannot associate .sb2 file to scratch2.0 offline editor on Linux Ubuntu

Thank you @Shoheiei and @mekizmo for the description, I post a quick update here for future reference.

1. Define .sb2 file's type
$ sudo vi /usr/share/mime/packages/Scratch2.xml

add:
<?xml version=“1.0” encoding=“UTF-8”?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info“>
<mime-type type=”application/x-scratch2“>
<comment>Scratch 2 Application</comment>
<glob pattern=”*.sb2“/>
</mime-type>
</mime-info>

2. Associate .sb2 file with Scratch 2 application
$ sudo vi /usr/share/applications/edu.media.mit.scratch2editor.desktop

add one line to the end of the file:
MimeType=application/x-scratch2

3. Add mime type to application defaults
$ sudo vi /usr/share/applications/defaults.list

add anywhere in the file:
application/x-scratch2=edu.media.mit.scratch2editor.desktop

4. Update application and mime type database
$ sudo update-desktop-database (*)
$ sudo update-mime-database /usr/share/mime

*(A quick fix might be needed here, see the end of this comment if you se errors related to evince.desktop.)

5. Associate icons with Scratch project files
$ sudo ln -s /opt/Scratch\ 2/share/icons/ProjectIcon128.png /usr/share/icons/Humanity/mimes/128/application-x-scratch2.png
$ sudo ln -s /opt/Scratch\ 2/share/icons/ProjectIcon48.png /usr/share/icons/Humanity/mimes/48/application-x-scratch2.png
$ sudo ln -s /opt/Scratch\ 2/share/icons/ProjectIcon32.png /usr/share/icons/Humanity/mimes/32/application-x-scratch2.png
$ sudo ln -s /opt/Scratch\ 2/share/icons/ProjectIcon16.png /usr/share/icons/Humanity/mimes/16/application-x-scratch2.png

Upadte icon cache:
$ sudo gtk-update-icon-cache /usr/share/icons/Humanity -f

All done.

—–
Quick fix if needed:

If update-desktop-database report a bug in evince.desktop mime definition remove one semicolon from a double semicolon between mime types: “application/x-ext-cb7;;application/oxps;”

Error in file “/usr/share/applications/evince.desktop”: “” is an invalid MIME type (“” does not contain a subtype)
Error in file “/usr/share/applications/evince.desktop”: “” is an invalid MIME type (“” does not contain a subtype)

*https://bugzilla.redhat.com/show_bug.cgi?id=1471474

After fixing Go back to step 4. to update databases.

Cannot associate .sb2 file to scratch2.0 offline editor on Linux Ubuntu

I am using ubuntu MATE 16.04. I have installed adobe air and scratch2. When I double click an sb2 file, scratch2 starts but it is blank and the scratch project which is in the sb2 file is not loaded. What can I do to open an sb2 scratch project with double click?

File: /usr/share/applications/scratch2.desktop

Encoding=UTF-8
Version=1.0
Type=Application
Exec=/opt/adobe-air-sdk/adobe-air/adobe-air /opt/adobe-air-sdk/scratch /Scratch-456.0.1.air
Icon=/opt/adobe-air-sdk/scratch/scratch.png
Terminal=false
Name=scratch2
Comment=Programming system and content development tool
Categories=Application;Education;Development;ComputerScience;
MimeType=application/scratch2project


File: /usr/share/mime/packages/scratchxml.xml
<?xml version=“1.0” encoding=“utf-8”?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info“>
<mime-type type=”application/scratch2project“>
<glob pattern=”*.sb2"/>
</mime-type>
</mime-info>

In the file /usr/share/applications/defaults.list I added the line:
application/scratch2project=scratch2.desktop


sudo chmod +x /usr/share/applications/scratch2.desktop
sudo update-desktop-database
sudo update-mime-database /usr/share/mime/
