Quartus 2.1.1 + Eclipse 8.8.1

And, now you should face a problem - the Eclipse can’t launch well !!!
How to fix this problem - Nios Eclipse crashes, free(): invalid pointer
My solution:

regis@ubuntu:~/intelFPGA_lite/20.1/quartus/linux64/jre64/bin$ ./java -version
openjdk version "1.8.0_265"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_265-b01)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.265-b01, mixed mode)

regis@ubuntu:~$ sudo apt install openjdk-8-jdk
regis@ubuntu:~$ java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-0ubuntu1~20.04-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)
regis@ubuntu:~$ 
regis@ubuntu:~$ cd ~/intelFPGA_lite/20.1/quartus/linux64
regis@ubuntu:~/intelFPGA_lite/20.1/quartus/linux64$ mv jre64 jre64.0
regis@ubuntu:~/intelFPGA_lite/20.1/quartus/linux64$ ln -s /lib/jvm/java-8-openjdk-amd64 jre64

Finally, all the Quartus and Eclipse are worked fine!!!
