What?! No it doesn't!

*You* are getting your commands muddled up, Ioannis!

AIUI:

`apt-get upgrade` attempts to *individually* upgrade all the installed
packages to their latest versions, separately.

`apt-get dist-upgrade` attempts to recursively upgrade the entire
distro - the whole tree of all packages - to the latest versions as
one single interlinked operation.

Neither will attempt to change release of the distro - not even on
Debian. That will only happen if you first edit /etc/apt/sources.list
and replace the old release name with the new release name, e.g.
"lenny" to "stretch".

In Ubuntu, the command to update from one release of the distro to the next is:

`do-release-upgrade`

Totally different and pretty hard to do by mistake. Note, although it
calls apt-get, the command itself is not an invocation of apt-get or
dpkg or any packaging tool.
