Hello.

I have tried to install jarec but I have not been successful. What kind of instructions could be given so that a beginner can do it. Or is it better to stay on Windows until I learn how to use Linux.
To automatically install jAReC on any Linux distribution based on Debian (including Raspberry Pi 32 or 64 bit), use the script from here:
https://www.yo3ggx.ro/jAReC/v4/jarec_installer.sh

No need to download or run anything manually.
Any previous saved config is not affected when updating (or even installung again).
Run the script from the Linux console.
To install:
sh jarec_installer.sh -i
To update(without loosing any configuration):
sh jarec_installer.sh -u

To run jarec v4:
./jarec.sh

This installer works on Chromebooks too (tested) and on Windows in WSL (not yet tested).

Please check again. It may be an issue with the DNS resolution for my domain (yo3ggx.ro).

I have now tried both linux on Ubuntu and raspberry pi4 devices. I have been helped via email by a friend who has managed to install jarec on linux. We have installed everything correctly, but the installation is not successful.

Are you using the latest installer script from here?
https://www.yo3ggx.ro/jAReC/v4/jarec_installer.sh

Was tested successfully on Ubuntu (20.04), latest Raspberry Pi OS (both 32 and 64 bit versions) and on Chrome OS (in Linux subsystem).

Yes, I use it. At first it seems to install the program, finally it says can't download the latest version from the central repository, try again later. I have tried to install about 100 times, but always the same result.

Try the following in the linux console:
wget https://www.yo3ggx.ro/jAReC/v4/jarec64.jar
Is the file downloaded?
If yes, then you are good to go, just run it with
./jarec.sh
If not, you have an issue with the name resolution for my web site (maybe because of some cached info).
Try:
ping www.yo3ggx.ro
Does my site answer to ping?

This is an installer script, does not contain the application.
You must "save as" to your Linux computer and then execute it.
In Linux you can download it from the console using wget.

Hey. still desperately trying to install jarec on raspberry with bad results. Everything is correct in my opinion, I don't understand how to proceed from this. I always get the same result when I try to run sh jarec_installer17.sh -i
