As you can see, I'm compiling a go application.
When I'm trying to run the last command it fails with this error:
/bin/sh: 1: /syzkaller-git/gopath/src/github.com/google/syzkaller/bin/syz-manager: not found
I've checked if the file is really exists and it does.
Tried to look online but nothing helped.
I've also tried to seperate this specific command from the one-lined RUN command, but it didn't help.

You are already at this path $SYZKALLER/gopath/src/github.com/google/syzkaller/
Dockerfile
cd $SYZKALLER/gopath/src/github.com/google/syzkaller/ && \
and you are trying to access the file in that path
./syzkaller-git/gopath/src/github.com/google/syzkaller/bin/syz-manager
It seems that you need to update the above to be either an absolute path or use the command like
./bin/syz-manager
