Jenkins agent failed to start up

Question

My jenkins agent failed to start up, and showing something weird. I know the error is something related to file encoding, but not sure how to fix it.

Jenkins master version: 2.319 The slave is running on Raspberry Pi, master is AMD64

My encoding is set UTF-8, not sure how it can be wrong

awt.toolkit sun.awt.X11.XToolkit
casc.jenkins.config /var/jenkins_home/casc_configs
executable-war  /usr/share/jenkins/jenkins.war
file.encoding   UTF-8
file.encoding.pkg   sun.io
file.separator  /

我使用此文档Launch Slave Agents via SSH使用Launch Slave Agents via SSH而不是Launch agent by connecting it to the controller作为漫游，这对我有用
