Do you have a Download link or similar for me to take a look at it.

Thanks for the reply. The Download link is https://downloadirpf.receita.fazenda.gov.br/irpf/2021/gcap/GCAP2021v1.1.zip

Run the following bunch of commands (simply select and paste into a Terminal):

wget -O ~/Downloads/GCAP2021v1.1.zip "https://downloadirpf.receita.fazenda.gov.br/irpf/2021/gcap/GCAP2021v1.1.zip"
mkdir -p ~/opt
unzip -d ~/opt/ ~/Downloads/GCAP2021v1.1.zip
wget -O ~/Downloads/openjdk-16.0.1_linux-x64_bin.tar.gz https://download.java.net/java/GA/jdk16.0.1/7147401fd7354114ac51ef3e1328291f/9/GPL/openjdk-16.0.1_linux-x64_bin.tar.gz
gzip -dc ~/Downloads/openjdk-16.0.1_linux-x64_bin.tar.gz | tar -xvf - -C ~/opt

echo JAVA_HOME=${JAVA_HOME:-~/opt/jdk-16.0.1} >> ~/.bashrc
