[DRE-maint] Bug#1030812: autopkgtest failure : it should not work with ruby-omniauth >= 2

[Lucas Kanashiro]

Source: ruby-omniauth-bitbucket
Version: 0.0.2-1.1
Severity: Serious

In ruby-omniauth-bitbucket gemspec we can see:

$ cat omniauth-bitbucket.gemspec | grep omniauth | grep dependency
   s.add_dependency 'omniauth', '~> 1.1'
   s.add_dependency 'omniauth-oauth', '~> 1.0'

This should not work since we already have ruby-omniauth >= 2 in testing 
and unstable:

$ rmadison -u debian ruby-omniauth
ruby-omniauth | 1.2.1-1+deb8u1  | oldoldoldstable   | source, all
ruby-omniauth | 1.3.1-1+deb9u1  | oldoldstable      | source, all
ruby-omniauth | 1.8.1-1~bpo9+1  | stretch-backports | source, all
ruby-omniauth | 1.8.1-1         | oldstable         | source, all
ruby-omniauth | 1.9.1-1~bpo10+1 | buster-backports  | source, all
ruby-omniauth | 1.9.1-1         | stable            | source, all
ruby-omniauth | 2.1.1-1         | testing           | source, all
ruby-omniauth | 2.1.1-1         | unstable          | source, all

This is not causing a FTBFS because we are not explicitly checking 
dependencies during tests (this is forced in autopkgtest), if the 
following change is added we can reproduce the same autopkgtest failure 
during the build:

     d/rules: check dependencies when running tests

     This demonstrates the FTBFS happening because we have ruby-omniauth 
 >= 2
     in the archive. The same failure is reproducible with autopkgtest.

  %:
         dh $@ --buildsystem=ruby --with ruby


All these mean that we likely have a broken ruby-omniauth-bitbucket in 
testing, we should not ship this package in a stable release. Upstream 
is inactive since 2017, so I do not expect any fix from them.
