I have a Alienware laptop which has Windows 10 and Ubuntu 19.04 installed. In my project, I want to use .NETCore, which is not compatible with Ubuntu 19.04, so I have to downgrade to 16.04. How can I downgrade from Ubuntu 19.04 to Ubuntu 16.04?

    Leave your system alone and run the older version in VirtualBox or other emulation software? – ivanivan Jun 21 at 23:58
  • Simply install 16.04 over 19.04. By either deleting the slices/partitions before installing 16.04. Or by asking the 16.04 installer to install on to the 19.04 slices/partitions. The installer will ask you if it's OK to overwrite/format those slices/partitions. – somebody Jun 22 at 1:25
  • @somebody that's a replace, not a downgrade. – roaima Jun 23 at 15:31
