I am new to the Linux environment. :-) I installed Ubuntu 18.04.2 LTS a few days ago. I have been for 20 years on Windows, so I need to study and experiment a lot now. A new beginning is always good! I guess... :-D

UPDATE - June 2024: I am back! I've had enough with Windows, no more dual boot system. I am now on Ubuntu 24.04 LTS.
