I have a stupid problem. To solve this level I installed Ubuntu (I know, I know) and have a problem with running stegsolve and steganabara (downloaded from WeChall). I have installed java jdk, then used javac and java commands. And after that I got: could not find or load main class error. I’ve tried to move files from one directory to another but stil it doesn’t work. I don’t know Java, so maybe somebody can help me with this?
