The drive is mounted as read-only as the error tells you; so either your mount was wrong, you tried to mount an unclean file-system (eg. one where windows hand’t closed it correctly as can happen with hibernate (which includes fast-boot), etc. Ubuntu releases are in format (there is no Ubuntu 18), with two releases for 2018; 18.04 LTS from April, and 18.10 coming out next week.
