Best install method for linux mint ver20?

It's really weird, if I fish out some old Sikuli code, then "wait" is it's familier light blue, "if" is navy blue.

But any new code I try to write has no coloring, it's all just black font.

the "wait" is it's familier light blue.
Is what I ment.

either I use "sikulixide-2.0.4.jar" or "sikulix-2.1.0.jar"
it doesn't matter, same problem.

seems you do not have Jython available and are running as JavaScript.

see: https://raiman.github.io/SikuliX1/downloads.html

That's probably the problem, when I downloaded "jython-standalone-2.7.1.jar" nothing happened when I ran it, and yes I made it executable.
So I ran it in the command line and it said

    user@computer:~/Downloads$ java -jar jython-standalone-2.7.1.jar -v -c
    Argument expected for the -c option
    user@computer:~/Downloads$ java -jar jython-standalone-2.7.1.jar
    WARNING: An illegal reflective access operation has occurred

There was alot more after the WARNING.

So I googled for other Jython installers and found "jython-installer-2.7.2.jar" which ran just fine, so I presumed that wasn't the issue.

just follow the steps on the mentioned page and use version 2.0.4 in any case.

Purge everything else from your system, that you have tried before.

I give up, been trying for hours.
Jython will not execute, it must not be compatible with this version of linux mint.
I'll try again in a few months.
Thanks for trying.

Hi Arminius,

It is compatible, am using mint 19 + and 20 and it works!

install the jython-installer-2.7.1.jar, and then sikulixide-2.0.4.jar

Open sikulixIDE and then go to "file>open special files" ..... and change this line, example: jython = /home/mint/jython2.7.1/jython.jar
Save it, close and open the sikulixIDE again.

then run all this commands:
sudo apt install libcanberra-gtk0 libcanberra-gtk-module
sudo apt install libopencv4.2-java openjdk-11-jre-headless
cd /usr/lib/jni/
sudo ln -s libopencv_java420.so libopencv_java.so
sudo apt-get install xdotool
sudo apt-get install wmctrl
sudo add-apt-repository ppa:alex-p/tesseract-ocr
sudo apt-get update
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev
sudo ldconfig

hope this helps.

Regards!
