I am came from Windows world and have a question about place to install applications. Some applications download to my Ubuntu desktop in tar.gz archives. I understand I can put these apps to any location. However, maybe there is a ideologically right place. For example, some apps installs to directories: /opt/, /usr/bin/, /usr/local/bin/. What should I prefer?

  • The question that I've marked as duplicate has good advice on this topic. It's worth being aware that packages that come as a tarball rather than from the Ubuntu repositories may not have the same level of safety checking though. – Arronical Apr 6 '16 at 8:42
