Are there any Ubuntu installation scenarios which still require manual partitioning? By "manual partitioning" I mean using the Something else option for partitioning of the pending Ubuntu installation.
On new installations of Ubuntu 17.04 and later a swap file is created by default instead of a swap partition. Among other things this saves valuable disk space on the SSD for users who have SSDs. For the purpose of limiting the scope of this question so it will not become too broad I am making these three assumptions.
- The computer has an SSD or NVMe that has enough available disk space to allow Ubuntu to be installed on it without giving Ubuntu less than the recommended disk space for a normal installation.
- Partitioning a small amount of disk space to install the bootloader and installing the bootloader on it can be done automatically by the Ubuntu installer. I know that sometimes the Ubuntu installer has problems correctly configuring the bootloader, but I am making this possible problem outside the scope of this question in order to keep it from being too broad.
- The Ubuntu installation is Ubuntu Desktop, not Ubuntu Server as I also mentioned in the question's title.
The Ubuntu installer includes a user-friendly option for installing Ubuntu alongside Windows. This option is designed to automatically create the necessary partitions for Ubuntu while preserving the existing Windows installation. Maybe this option doesn't work for some multiboot scenarios. Therefore I am including it in the scope of this question.
