Package: how-can-i-help
Version: 1
Severity: normal

Dear Maintainer,

upon upgrading the ruby-debian package from 0.3.8+b1 to 0.3.8+b2
I got the following error message:

/usr/lib/ruby/vendor_ruby/debian.rb:24:in `require': no such file to load -- 
debian_version (LoadError)
  from 
/usr/lib/ruby/vendor_ruby/debian.rb:24
  from /usr/bin/how-can-i-help:20:in 
`require'
  from /usr/bin/how-can-i-help:20
E: Problem executing scripts DPkg::Post-Invoke '[ ! -e /usr/bin/how-can-i-help 
] || /usr/bin/how-can-i-help'
E: Sub-process returned an error code

The upgrade of ruby-debian iteslf was not afected (according to apt-check).

Cheers

Armin

Bug#734156: how-can-i-help: no such file to load -- debian_version after upgrade of ruby-debian package

2014-01-04 Thread Lucas Nussbaum
@ Armin: you install to 'apt-get install ruby'

Hi Debian-Ruby,

The bug report below is interesting. The user has ruby1.8 installed, that
provides ruby-interpreter. As a result, h-c-i-h Depends' line is satisfied:
Depends: ruby | ruby-interpreter, ruby-debian, ruby-json

However, since ruby-debian no longer has support for ruby1.8, h-c-i-h can't use
ruby1.8.

I'm not sure of how to address this situation. For now, I'll just drop
|ruby-interpreter. But the overall handling of dependencies when switching Ruby
versions seems fragile. And there are 578 occurences of Depends: ruby
| ruby-interpreter in the archive, which scares me a bit.

Maybe ruby-defaults should provide a symlink to the default ruby version
that we could use in shebangs (#!/usr/bin/ruby-debian-default)? That
would allow to ensure that hcih really runs with ruby1.9.3 even if the
user used update-alternatives to switch to another version.
