Bug#1057309: src:haskell-pandoc binary package names conflict with src:pandoc binary packages

[Hannes von Haugwitz]

Source: haskell-pandoc
Version: 3.0.1-2
Severity: serious
Control: affects -1 src:pandoc

Hi,

The binary packages provided by src:haskell-pandoc conflict with the
binary packages of src:pandoc; violationg Debian Policy 3.1 ("Every
package must have a name that’s unique within the Debian archive.").

This also makes the pandoc binary package from src:pandoc uninstallable
in unstable:


# apt policy pandoc pandoc-data
pandoc:
  Installed: (none)
  Candidate: 2.17.1.1-3
  Version table:
     2.17.1.1-3 500
        500 mirror+file:/etc/apt/mirrors/debian.list unstable/main amd64 Packages
pandoc-data:
  Installed: (none)
  Candidate: 3.0.1-2
  Version table:
     3.0.1-2 500
        500 mirror+file:/etc/apt/mirrors/debian.list unstable/main amd64 Packages
     2.17.1.1-3 500
        500 mirror+file:/etc/apt/mirrors/debian.list unstable/main amd64 Packages

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 pandoc : Depends: pandoc-data (< 2.17.1.1-3.~) but 3.0.1-2 is to be installed
E: Unable to correct problems, you have held broken packages.


As a workaround you can specify the matching version of pandoc-data:

# apt install pandoc pandoc-data=2.17.1.1-3

Best regards
