# - requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command

Thanks to Debian's upgrade process, it should be relatively simple to either upgrade Ubuntu 16.04 to 18.04 (both LTS) or to upgrade Ubuntu 17.10 to 18.04 LTS Bionic Beaver.
