Raspberry Pi 4 的 Java、Selenium、Debian，geckodriver 错误打印垃圾

Question

Im making a Java program that uses Selenium to access webpages and retrieve data, it works on Windows, pure Debian and Ubuntu but when I run it on my RPI4 with Debian for Raspberry Pi 4, the geckodriver gives cryptic errors and the program crashes.

The errors are as follows:

/usr/local/bin/geckodriver: 2: /usr/local/bin/geckodriver: YM9sHIiHMIi԰: not found
/usr/local/bin/geckodriver: 1: /usr/local/bin/geckodriver: Syntax error: end of file unexpected (expecting ")")

The program also creates this file: ''$'\001\022\002''@@'$'\230\204''y@8'$'\a''@'$'\035\032\001\005''@@t'$'\202''6t'$'\202''6' , but I did not program that myself. This does not happen when the program works, only when it crashes.

It may be that it just does not work but I would like to know the answer. The geckodriver is correcly in the PATH inside the program and is executable Also, firefox-esr and default-jre.

Thank you!

1. With regard to the "garbage" being printed when using
   'gekodriver', perhaps it is because its not meant for the platform
   (hardware + operating_system) you are using?
2. With regard to

Exception in thread "main" org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:29555 Build info: version: 'unknown', revision: 'unknown', time: 'unknown' System info: host: 'raspy', ip: '192.168.1.33', os.name: 'Linux', os.arch: 'aarch64', os.version: '5.9.0-0.bpo.5-arm64', java.version: '11.0.9.1'

That would indicate that there is nothing listening on 29555 on tcp6 ip protocol.

Above are just guesses that you can try looking into until someone better informed comes along.
