Since the installation process moved over to snap, I cannot run Processing 4.4.4. Installation via snap works fine with a few prior steps (below) but execution generates multiple X11 window server and other errors. This affects both X86 and ARM Chromebooks.
Prior to Processing 4.4, installation was via a .tgz file which worked fine with x86 and ARM Chromebooks (using these instructions, and this gotcha for ARM processors). Processing 4.4 appears to use snap exclusively which does not work out of the box with Chromebooks, but it can be made to work with these command line workarounds in the Linux Development Environment:
$ sudo apt install squashfstools
$ sudo apt install libsquashfuse0 squashfuse fuse
$ sudo apt install snapd
Restart your terminal session, then install a small test application
$ sudo snap install hello-world
Then run it from the command line to make sure that snaps are working correctly.
$ hello-world
Hello World!
If you see Hello World! then you’re good to go.
Now install Processing with
$ sudo snap install processing
processing 4.4.4 from Processing installed
When I start up Processing from the command line, I get a long list of X11, java and other errors that I have no idea how to fix.
$ processing

I get the same errors on both an x86 and ARM Chromebook.
So, right now I’m stuck using Processing 4.3.4 which is the last version that provided .tgz installation files. So far, I have not been able to get version 4.4.4 running.
Is there a fix for this X11 window server error, or alternatively, will a .tgz installer be made available in addition to the snap file for current and future Processing versions? I guess that’s a question for the Processing github, but I thought I should ask here first. If snap is the preferred installer mechanism, then I’d really like to get it working on my Chromebook.
Thanks!
