Hi, I digged a bit deeper as why we can only use electron11 and only, if you copy the complete electron11 into the scratch-installation.

• found this: https://gist.github.com/lyshie/0c49393076b8b375ca1bd98c28f95fb0#gistcomment-3808921 and found that I can let scratch run with electron11, electron13, electron14 and electron (16) using the trick to "disable" contextIsolation

• however, the images are missing / not loading if the systemwide electron is used and only shown if electron is copied to scratch-installation. I did not find a way to circumvent this.

• the other deprecation issues should be looked upon closely: "DeprecationWarning: Buffer()" from electron11 upwards, e.g.

• there is another problem: electron14 and upwards do not show the "save to computer" dialog, but GTK shows an error message:

 Gtk: gtk_native_dialog_run: assertion '!priv->visible' failed

To sum up:

• electron13 is the maximum that seems to work for now and only when copied to the scratch-installation
• the electron13 (or whichever) does not need to be installed systemwide just for the packaging. Especially when you use a not maintained version (11).

@etaboon I just made it, thank you

Queenmedley was right: there are no images showed in "choose a sprite".

This is the same for "choose a background" (no images) and for "choose a sound" (no sound except the cat's one).

Proposal to fix this issue (package size will grow 113.6MB to 172.6MB but works for me), to make this work, I had to rename the downloaded file scratch3 to scratch3.sh. The installed file will still be named "scratch3":

For the bash script:

$ diff scratch3 scratch3.sh
3c3
< exec electron /usr/share/scratch3/app.asar "$@"
---
> exec /usr/share/scratch3/electron "$@"

Tested successfully with Scratch3 3.18.1 and 3.20.1.

Scratch3 stopped working for me:

a window opens with "Scratch is loading..." forever.

Had to replace electron with electron11 as a workaround:

There are no images showed in "choose a sprite".

Adding this line fixed this issue indeed. Many thanks

Thanks for your help

@PCITechie This package runs natively, without wine. It just extracts the electron resources (which are platform-independent) from the Windows installer.

In fact it does what the source of your scratch3-bin package does, only without re-packaing to .deb.

Also, since this package is currently up-to-date, unlike scratch3-bin, I think it would be great to merge scratch3-bin into this package, in order to reduce duplication and confusion of users.

I advise you to call this package "scratch3-win32" instead of scratch3 so people know it runs in wine and not natively.
