I have installed NetBeans 8 in /opt folder due to permission reasons. I created a symlink and worked in my local from the morning. Suddenly, now it's not opening. IT does not seem to be crashed but I don't know why.
Any suggestions please
Open your Linux computer's command terminal by pressing CTRL + ALT + T keys on your keyboard. Once the command terminal is up, type in the following command: "chmod +x filename". The "filename" in the command refers to the name of the NetBeans installer file you downloaded. The NetBeans setup window will then appear.
Installing Netbeans IDE on Ubuntu using Apt package managerIf you search for Netbeans in Ubuntu Software Center, you'll find two Netbeans available. The Apache Netbeans is the snap version which is bigger in download size but gives you the latest Netbeans. You can install it in one click. No need to open terminal.
Delete the version you downloaded previously for netbeans 8.1. Install the latest jdk preferably Java 8. Then download netbeans 8.1 from the official website. Run the exe and install all the updates you need.
First:
sudo apt autoremove netbeans
Download netbeans 8.2 from: https://netbeans.org/
after you download the file, go to the directory and:
sudo apt-get install default-jdk
cd Downloads
or wherever the script netbeans-8.2-linux.sh is. Then
sudo chmod +x netbeans-8.2-linux.sh
./netbeans-8.2-linux.sh
Follow the instructions. If the field for JDK is empty, reinstall it, and then run the script again. You can remove JDK 8 too. This is not necessary, up to you.
