[Aptitude-devel] Bug#802943: aptitude: Small problems printing information about conflicts and virtual packages

[Manuel A. Fernandez Montecelo]

Package: aptitude
Version: 0.7.4-1
Severity: minor

>From bug #799918 (opening a new one to avoid all of the noise in that bug
report):

  jidanni:
  OK now full-upgrade prints "- libgdal1i, but 1.11.3+dfsg-1~exp1 is to be
  installed." twice! On the same line too.
  
  (Note I always use the CLI aptitude and never curses.)

    qgis : Depends: libgdal.so.1-1.11.2 which is a virtual package, provided by:
                     - libgdal1i, but 1.11.3+dfsg-1~exp1 is to be installed.                  - libgdal1i, but 1.11.3+dfsg-1~exp1 is to be installed.
		   The following actions will resolve these dependencies:

     Remove the following packages:
     1)     qgis


In this case it looks like libgdal1i versions older than 1.11.3+dfsg-1~exp1
provided libgdal.so.1-1.11.2, while the newer does not.

Printing versions of the package providing the virtual package would inform
better of the situation, and as a consequence it would make easier to find out /
explain the reasons to have the conflicts/broken dependencies (and as a side
effect, maybe avoid bugs reported as if it was a problem in aptitude rather than
in packaging or transitions).

Also, when printing twice (if they are several versions providing the virtual
package), should do it in two lines rather than one, have nice formatting,
perhaps not a dot in the end, etc.


Cheers.
