Ubuntu 18.04 Environment Configuration (from beginning to giving up)
1. Install Ubuntu
- make sure that the /swap partition is twice larger than the computer memory.
- 25GB is enough for root /.
- The /boot partition should be use as 'EFI system partition'. 1GB is enough.
- The / partition should be of 'primary' type. Others should be 'logical'.
