How can I check my Linux version? The command “uname -r” shows the version of the Linux kernel that you’re currently using. You’ll now see which Linux kernel you’re using.
How do I know if I have Debian or Ubuntu? The preferred method to check your Debian version is to use the lsb_release utility which displays LSB (Linux Standard Base) information about the Linux distribution. This method will work no matter which desktop environment or Debian version you are running. Your Debian version will be shown in the Description line.
Does Debian have a GUI? GUI applications. Many useful GUI applications are available on Debian now. Installing software packages such as scribus (KDE) on GNOME desktop environment are quite acceptable since corresponding functionality is not available under GNOME desktop environment.
Which Debian version is Kali Linux? What version of Debian is the current Kali Linux 2019.2? Kali is based on the rolling release of Debian and therefore has no specific release number. Just consider it to be “bleeding edge” Debian. I hope that answers your question.
