Bug#826110: swh-plugins, vocoder-ladspa: error when trying to install together

[trebmuh]

Hi all,


Yes ... both packages shipping same plugin now ...
What would be correct solution ?
Replace Breaks Conflicts ?
Or maybe just remove vocoder-ladspa package from archive ...
If I understand right this plugin has been moved to swh-plugins
project by same people which maintain vocoder-ladspa package.

https://packages.debian.org/sid/vocoder-ladspa
https://github.com/swh/ladspa/commit/2e212812910f989e48566b2c71791bcc8db8f8ef



What's about removing vocoder-ladspa from the archive now that it has 
been upstreamed by LMMS to SWH, and making LMMS depends on swh-ladspa?

Bug#826110: swh-plugins,vocoder-ladspa: error when trying to install together

[Andreas Beckmann]

Package: swh-plugins,vocoder-ladspa
Severity: serious
User: trei...@debian.org
Usertags: edos-file-overwrite
Control: found -1 0.4.16+git20160602~repack1-1
Control: found -1 1.1.3-2

Hi,

automatic installation tests of packages that share a file and at the
same time do not conflict by their package dependency relationships has
detected the following problem:

  Selecting previously unselected package vocoder-ladspa.
  Preparing to unpack .../vocoder-ladspa_1.1.3-2_amd64.deb ...
  Unpacking vocoder-ladspa (1.1.3-2) ...
  dpkg: error processing archive 
/var/cache/apt/archives/vocoder-ladspa_1.1.3-2_amd64.deb (--unpack):
   trying to overwrite '/usr/lib/ladspa/vocoder_1337.so', which is also in 
package swh-plugins 0.4.16+git20160602~repack1-1
  Errors were encountered while processing:
   /var/cache/apt/archives/vocoder-ladspa_1.1.3-2_amd64.deb

This is a serious bug as it makes installation fail, and violates
sections 7.6.1 and 10.1 of the policy. An optimal solution would
consist in only one of the packages installing that file, and renaming
or removing the file in the other package. Depending on the
circumstances you might also consider Replace relations or file
diversions. If the conflicting situation cannot be resolved then, as a
last resort, the two packages have to declare a mutual
Conflict. Please take into account that Replaces, Conflicts and
diversions should only be used when packages provide different
implementations for the same functionality.

Here is a list of files that are known to be shared by both packages
(according to the Contents file for sid/amd64, which may be
slightly out of sync):

  usr/lib/ladspa/vocoder_1337.so

This bug is assigned to both packages. If you, the maintainers of
the two packages in question, have agreed on which of the packages will
resolve the problem please reassign the bug to that package. You may
also register in the BTS that the other package is affected by the bug.

Cheers,

Andreas
