[Pkg-gambas-devel] Bug#814862: gambas3: fails to find an upgrade path from jessie to stretch

[Andreas Beckmann]

Package: gambas3
Version: 3.8.4-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'jessie'.
It installed fine in 'jessie', then the upgrade to 'stretch' fails and
the jessie version is kept installed rather than upgraded.

>From the attached log (scroll to the bottom...):

This is apt problemresolver output from the jessie->stretch upgrade.

[...]
  The following NEW packages will be installed:
[...]
  The following packages have been kept back:
    gambas3 gambas3-ide
  The following packages will be upgraded:
[...]

[...]
  Investigating (0) gambas3-ide [ amd64 ] < 3.5.4-2 -> 3.8.4-2 > ( devel )
  Broken gambas3-ide:amd64 Conflicts on gambas3-gb-qt4 [ amd64 ] < 3.5.4-2+b1 -> 3.8.4-2 > ( libdevel )
    Considering gambas3-gb-qt4:amd64 12 as a solution to gambas3-ide:amd64 1
    Holding Back gambas3-ide:amd64 rather than change gambas3-gb-qt4:amd64

   Try to Re-Instate (1) gambas3:amd64
  Done

So what happened here?

gambas3-gb-qt4 is installed in jessie and an upgradable candidate,
but gambas3-ide, which is also installed in jessie, now
Conflicts: gambas3-gb-qt4.

gambas3-gb-qt4 has a score of 12 (there are several rdepends) while the
gambas3-ide and gambas3 meta-packages only have rather low scores of
1 and 0, respectively. So gambas3-gb-qt4 wins and does not get removed.

So one ends up with the jessie versions of gambas3 and gambas3-ide still
installed while all other packages have been upgraded to the stretch
version.

Right now I have no suggestions how to solve this upgrade issue.

That Conflicts: gambas3-gb-qt4 is nasty. Is the gambas3-gb-qt4 package
still needed? Could it be converted into a transitional package?


cheers,

Andreas
