Como instalar o Scratch 2 no Ubuntu 16.10. ou 17.04 (64 bits)?

Question

Eu preciso instalar o Adobe Air no Ubuntu 16.10 / 17.04 com o Scratch 2. offline Há muitos anos sem ar no Linux, então há várias soluções alternativas. Um que funcionou para mim até o Ubuntu 16.04 (usando o instalador binário Air):

# install i386 necessary 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
# install keyring
$ sudo apt-get install libgnome-keyring0:i386
# make keyring visible for Air
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0 
# download Adobe Air installer
$ wget  http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRInstaller.bin
# run it
$ sudo chmod +x AdobeAIRInstaller.bin
$ sudo ./AdobeAIRInstaller.bin

mas em 16.10 / 17.4 ele termina com o erro do instalador:

% bl0ck_qu0te%

Qual é obviamente uma mensagem de erro falsa, pois dpkg-deb e ar estão instalados:

$ dpkg-deb --version
Debian 'dpkg-deb' package management program version 1.18.10 (amd64).
$ ar --version
GNU ar (GNU Binutils for Ubuntu) 2.28

O arquivo de log da instalação do Adobe Air é de /root/.appdata/Adobe/AIR/Logs/Install.log

Então eu encontrei outra maneira de instalar um pacote do Adobe Air via deb (eu não sabia antes):

$ wget http://airdownload.adobe.com/air/lin/download/2.6/adobeair.deb
$ sudo dpkg -i adobeair.deb

E voilà! O Adobe Air está instalado no Ubuntu 16.10 / 17.04.
Agora instale o Scratch 2.

# Find the latest Scratch AIR file link from https://scratch.mit.edu/scratch2download/
$ wget https://scratch.mit.edu/scratchr2/static/sa/Scratch-456.0.1.air
$ sudo Adobe\ AIR\ Application\ Installer ./Scratch-456.0.1.air 

e novamente o mesmo erro:

% bl0ck_qu0te%

Parece que um Adobe Air não mantido não pode mais reproduzir com o novo dpkg-deb e ar .

Alguma dica para o Scratch 2 off-line no Ubuntu 16.10 / 17.04?

    

Answer 1

Eu tenho jogado com esse par de horas. Primeiro, tentei rastrear o Adobe Air Application Installer e descobrir o que está acontecendo dentro de você.

$ sudo strace -s 500 -t -o air_scratch.txt Adobe\ AIR/Versions/1.0/Adobe\ AIR\ Application\ Installer ~/Downloads/Scratch-456.0.1.air 

E eu encontrei esta linha:

read(18, "dpkg-deb: error: treewalk root /tmp/FlashTmp.3TWnKI/build/DEBIAN is not a directory\n", 4096) = 84

Parece que o novo dpkg não pode manipular links como o anterior. Isso pode ser corrigido pelo script wrapper colocado, por exemplo, para ~/air/bin/dpkg e alterando a variável PATH antes de executar o Adobe Air Application Installer. Infelizmente, o Scratch não pode ser instalado sem o sudo, e trocar PATH pelo sudo não é tão fácil.

Então eu encontrei um fórum polonês de contribuintes insatisfeitos, que estão resolvendo problemas semelhantes (eles precisam executar algum aplicativo Air do ministério das finanças no Debian / Ubuntu): link .

E dentro desse fórum eu encontrei algumas dicas, como executar o Scratch 2 no Ubuntu 16.10 / 17.04 (mesmo sem adobeair.deb installation).

Esta é minha solução final de trabalho, testada em instalações limpas.

# 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

# 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

# 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

# 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

# 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

Criar lançador:

$ 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_

$ chmod +x /usr/share/applications/Scratch2.desktop

E é isso. A primeira execução é um pouco mais longa, já que o Air está descompactando o aplicativo Scratch 2 na pasta ~/.appdata/edu.media.mit.Scratch2Editor .
