Debian install fails

[Rolf Niggemann]

Dear all,

I want to install concerto-lite package on Debian 11.

sudo apt install concerto-lite
The install aborts with error:

concerto-lite (2.3.6) wird eingerichtet ... ERROR: While executing gem ... (Gem::OptionParser::InvalidOption) invalid option: --no-ri Did you mean? no-force dpkg: Fehler beim Bearbeiten des Paketes concerto-lite (--configure): »installiertes post-installation-Skript des Paketes concerto-lite«-Unterprozess gab den Fehlerwert 1 zurück

I believe the option '--no-ri' is removed and must be replaced with '--no-document' .
How to do that?

Thank you for help.

I found a fix with the help of some googleing:

Inside the deb package is a file "control.tar.gz - postinst"

In postinst change the line
gem install bundler --no-ri --no-rdoc
to
gem install bundler --no-document

This is due to the arguments --no-ri and --no-rdoc are removed and are replaced by --no-document.

Then build a new .deb file (including new version number) and the install completes without error.
I do not know how to implement the fix here, so maybe someone can help and build an official new package?
