Oh please! And you are the only one who does? Ive been working with Debian
since 1997 for sure i didnt wait for you to explain me how apt works!

Nothing is wrong with the dist-upgrade advise it will bring your system
most uptodate. In my case running upgrade was going to do partial one only
which means there is a good chance the database was going to be left in
inconsistant state. Running dist-upgrade did the job.

At the end of the day you are the one who knows your system best. If you
are running mixed source list you really need to know very well what are
you doing.
