How to install scratch 2 in ubuntu 18.04

Solution 1:

... and this works for me on ubuntu 18.04 (64bit)

1. install necesary i386 libraries

   $ sudo apt-get install libgtk2.0-0:i386 libstdc++6:i386 libxml2:i386 libxslt1.1:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386 libqt4-qt3support:i386 libgnome-keyring0:i386 libnss-mdns:i386 libnss3:i386
   

2. make keyring visible for Adobe Air

   $ sudo ln -s /usr/lib/i386-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
   $ sudo ln -s /usr/lib/i386-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0
   

3. Download Adobe Air

   $ cd ~/Downloads
   $ wget http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRSDK.tbz2
   $ sudo mkdir /opt/adobe-air-sdk
   $ sudo tar jxf AdobeAIRSDK.tbz2 -C /opt/adobe-air-sdk
   

4. Download Air runtime/SDK from Archlinux

   $ wget https://aur.archlinux.org/cgit/aur.git/snapshot/adobe-air.tar.gz
   $ sudo tar xvf adobe-air.tar.gz -C /opt/adobe-air-sdk
   $ sudo chmod +x /opt/adobe-air-sdk/adobe-air/adobe-air
   

5. Get actual scratch file URL from https://scratch.mit.edu/scratch2download/

   $ sudo mkdir /opt/adobe-air-sdk/scratch
   $ wget https://scratch.mit.edu/scratchr2/static/sa/Scratch-456.0.1.air
   $ sudo cp Scratch-456.0.1.air /opt/adobe-air-sdk/scratch/
   $ cp Scratch-456.0.1.air /tmp/
   $ cd /tmp/
   $ unzip /tmp/Scratch-456.0.1.air
   $ sudo cp /tmp/icons/AppIcon128.png /opt/adobe-air-sdk/scratch/scratch.png
   

6. Create Desktop Shortcut

   $ sudo cat << _EOF_ > /usr/share/applications/Scratch2.desktop
   [Desktop Entry]
   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=Scratch 2
   Comment=Programming system and content development tool
   Categories=Application;Education;Development;ComputerScience;
   MimeType=application/x-scratch-project
   _EOF_
   
   $ sudo chmod +x /usr/share/applications/Scratch2.desktop
   

Solution 2:

I found an Ubuntu educational fork for Scratch 3 beta version. You just need to change language from french to english =)

For scratch 1.4 just type:

 sudo apt-get install scratch

I'm not in informatics, but I think in the 1.4 version a library like Qt4 is missing for the fonts.

For Scratch 2, I didn't manage to install Adobe Air 20, it bugs too much on Wine install :/

Please don't over spam this french academy, as I don't believe at all their Bandwith to handle World's download neither a town's download. Just add the download to a normal download website for Ubuntu packages.

More over there must be an official link outside of the one I proposed as it's official Scratch 3 official beta version online works with Linux. Must be somewhere in GitHub or something?

Solution 3:

Install adobe air as state on https://www.noobslab.com/2015/05/adobeair-is-now-available-for-ubuntu.html

wget -O adobe-air_amd64.deb http://drive.noobslab.com/data/apps/AdobeAir/adobeair_2.6.0.2_amd64.deb
sudo dpkg -i adobe-air_amd64.deb 
sudo apt install -f

Install pixbuf stuff

 sudo apt-get install gtk2-engines-pixbuf:i386

Install scratch (use 455, newer versions need newer AIR)

wget https://scratch.mit.edu/scratchr2/static/sa/Scratch-455.air

Start

/opt/adobe-air-sdk/adobe-air/adobe-air ./Scratch-455.air
