Describe the bug

For the Modpack FTB Direwolf20 1.18, Version 1.4.1 and Target arm linux,
the start.sh script still contains a placeholder value for the jar file to run.

./jre/jdk-17.0.2+8-jre/bin/java -javaagent:log4jfix/Log4jPatcher-1.0.0.jar -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -Xmx6144M -Xms4096M -jar insert-jar-here.jar nogui

Steps to reproduce

1. download serverfiles for arm linux
2. run installer
3. set permissions
4. try to run ./start.sh
5. returns error "Unable to access jarfile insert-jar-here.jar"

Expected behaviour

running start.sh should start the server

Screenshots

No response

Additional information

I tried replacing "insert-jar-here.jar" with "minecraft_server.1.18.2.jar", this started a server i could join to, but it was just a vanilla server with corrupted world gen

Did you look at the entire install log for errors? If the Forge installer doesn't run successfully, it won't update the start.sh file with the correct jar file, or reference to the unix_args.txt file. See my issue FTBTeam/FTB-App#618, specifically here, where I mention that running the installer without a functioning Java in your $PATH will lead to that same result:

This results in the above log tail, with a "failed Forge install" message, and start.sh isn't valid:

./jre/jdk-17.0.2+8-jre/bin/java -javaagent:log4jfix/Log4jPatcher-1.0.0.jar -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -Xmx6144M -Xms4096M -jar insert-jar-here.jar nogui
