I'm trying to install Ubuntu Server 22.04 lts on a free partition of an external ssd disk. The ssd disk contains Linux Mint Vera. During the installation, at the section: Storage configuration: a message appears: "To continue you need to: Mount a file system at /". What must I do to mount that partition in order to continue the installation? My intention is to boot dually between Linux Mint and Ubuntu Server.
Thanks for the response.
