I want to update my Ubuntu 17.04 to 17.10 while preserving most of the system settings. I currently can't update it using update-manager and also
do-release-upgrade due to this issue so I thought if I could update using Live CD but when I booted the Live CD and went through the installer to selection page for some reason there were only 3 options available:
- Erase Ubuntu 17.04 and install Ubuntu 17.10 alongside Windows
- Erase disk and install Ubuntu
- Something else
Rest all options were grayed out. While searching on the internet, I came across
cdromupgrade but that doesn't exist in the ISO. Is there any way I can update from the ISO/Live CD?
