I tried the command dos2unix in path /usr/share/openstego/openstego But I get the same result

I solved with by editing the accessibility.properties file for openjdk and comment this line: assistive_technologies=org.GNOME.Accessibility.AtkWrapper But I'm not an expert with Java and i don't know if it's a safe method to solve this issue... If it's ok, you can close this issue. Thank you

I think that change should be fine. Seems that many people face this with Ubuntu java.
