Thanks a lot @bert003 and @bidaian
I'll bring this to arch.

Dear Sirs,

I have followed the procedure and I obtained a working .deb installation file using the latest verison "Scratch-desktop v3.26.0"
After installed into Linux Mint 20.3 MATE 64bit, I have the ""SCRATCH IS LOADING" screen..
Then I try to modify the main.js
I had problem installing via terminal, of "npm install asar", so I used SNAP to install asar...

sudo rm /etc/apt/preferences.d/nosnap.pref && sudo apt update && sudo snap install asar --classic

after that,
cd /lib/scratch-desktop/resources sudo asar extract app.asar modif cd modif sudo nano main.js (and into the line "nodeIntegration: true" I changed it nto: "true,\n contextIsolation: false\n") cd .. sudo asar pack modif app.asar
Now If I launch Scratch, NO screen appear, anche the program close without showimg the Scratch windows (this is differemt from the starting issue with freezing screen "SCRATCH IS LOADING" )

Try to start Scratch via terminal, I obtain:

linux@Mint:/lib/scratch-desktop/resources$ /usr/lib/scratch-desktop/electron "/usr/lib/scratch-desktop/Scratch-desktop"
A JavaScript error occurred in the main process Uncaught Exception: SyntaxError: Unexpected identifier at Object.call (/usr/lib/scratch-desktop/resources/app.asar/main.js:1323:181) at e (/usr/lib/scratch-desktop/resources/app.asar/webpack:/webpack/bootstrap:25:22) at Object.call (/usr/lib/scratch-desktop/resources/app.asar/main.js:1328:97) at __webpack_require__ (/usr/lib/scratch-desktop/resources/app.asar/webpack:/webpack/bootstrap:25:22) at module.exports../node_modules/ajv/lib/ajv.js (/usr/lib/scratch-desktop/resources/app.asar/webpack:/webpack/bootstrap:96:10) at Object.<anonymous> (/usr/lib/scratch-desktop/resources/app.asar/main.js:1:1052) at Module._compile (node:internal/modules/cjs/loader:1116:14) at Object.Module._extensions..js (node:internal/modules/cjs/loader:1169:10) at Module.load (node:internal/modules/cjs/loader:988:32) at Module._load (node:internal/modules/cjs/loader:829:12) libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null) [2870:0122/203824.204885:ERROR:viz_main_impl.cc(161)] Exiting GPU process due to errors during initialization libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null) [2886:0122/203824.280940:ERROR:sandbox_linux.cc(376)] InitializeSandbox() called with multiple threads in process gpu-process.

Seems that the ASAR procedure to modify the file main.js has broke someting...Is it possible to solve this problem?
Many thanks in advance for your job!

I am trying to install .deb package on Ubuntu 22.04. I could successfully get upto cd /tmp/scratch-desktop/resources/ command.
However, when I try the next command i.e. ~/node_modules/.bin/asar extract app.asar app, I get /home/user/node_modules/.bin/asar: No such file or directory.
Please help.

@shaileshparanjpe : To avoid that problem just install asar with:
npm install @electron/asar

Anyway, if you're using Ubuntu, instead of pasting all those lines, the only thing you need to do is this:

wget https://gist.githubusercontent.com/lyshie/0c49393076b8b375ca1bd98c28f95fb0/raw/e6bca7386ac58a99ce8de07489481a2e579b170f/create-deb.sh
chmod +x create-deb.sh
,/create-deb.sh

That's it.

If you're using a Raspberry Pi 4 with Ubuntu, you should change the architecture to arm64 (or armhf if you're running on 32-bit) in the config-deb.json file (you'll have to download it manually, edit it, then remove the "wget -c -O /tmp/config-rpm.json ..." line from the create-deb.sh file to avoid overwriting your arch modification). But this version of Scratch won't have access to the GPIO and SenseHat extensions for the Raspberry Pi, sadly, since those extensions are exclusive to the special version of Scratch Desktop that comes with the official Raspberry Pi OS.

Thank you for your job, @lyshie !!

Thank you for this tutorial, is really helpful. Keep up with the good work.
