Public bug reported:
PRETTY_NAME="Ubuntu quantal (12.10)"
VERSION="12.10, Quantal Quetzal"
Package: ruby-commandline
Priority: optional
Section: ruby
Installed-Size: 96
Maintainer: Ubuntu Developers <ubuntu-devel-disc...@lists.ubuntu.com>
Architecture: all
Version: 0.7.10-13
Ruby-Versions: ruby1.9.1 ruby1.8
After installing dhelp which uses ruby, I was frequently seeing during
package installation the error message
ERROR: comparison of String with 10 failed
following the invocation of dhelp information processing for the
particular package.
In fact, just invoking dhelp_parse at the command line produces the
error message
dhelp_parse
ERROR: comparison of String with 10 failed
After investigation, it was ascertained that this error was due to console width
being obtained from the environmental variable COLUMNS in the form of a string
and not being automatically converted to an integer.
Therefore the following fix of changing console width from a string to
an integer needed to be applied to
/usr/lib/ruby/vendor_ruby/commandline/application.rb
