Comment #4 by gbWilly GAMBOS:

Nope, I'm saying that the upgrade failed, I never said I used it.

This is what the logs says when upgrading jessie with gambas3.5.4 to stretch with gambas3.8.4:

--------------------------------------------

So, in short all but gambas3 and gambas3-ide where upgraded.
Why did gambas3 and gambas3-ide not upgrade.
The answer is in the Debian control file for making the packages.

If I look in the control file for Gambas3 (3.8.4) both gambas3 and gambas3-ide are packaged to require qt5 instead of qt4 (see below).
gambas3-ide even conflicts with gambas3-gb-qt4.

Description: Complete visual development environment for Gambas
 Gambas is a free development environment based on a Basic interpreter
 with object extensions, like Visual Basic(tm) (but it is NOT a clone!).
 With Gambas, you can quickly design your program GUI, access MySQL or
 PostgreSQL databases, pilot KDE applications with DCOP, translate your
 program into many languages, and so on...
 .
 This package doesn't include anything: it is a metapackage to install the
 IDE and all the available Gambas components...

 .
 This package includes the Gambas Development Environment.
--------------------------------------------

This is done because qt4 will no longer be used in stretch (so to make sure the qt5 packages are used instead)
Gambas3 (3.5.4) is packaged to use qt4. This seems to cause the problem with upgrading 3.5.4 to 3.8.4

So, what is a possible solution here?
1. Does the packager have to change something in his/her control file and repackage? If so, what needs to change?
AND/OR
2. Is there maybe something that can be done from within Gambas to solve the problem?
