How can I activate info: links in Konqueror

  • 772

man: and help: work fine, but if I enter an info: link it says:

The requested operation could not be completed Cannot Initiate the info Protocol Technical Reason: Unable to Launch Process

Possible Causes:

The program which provides compatibility with this protocol may not have been updated with your last update of KDE. This can cause the program to be incompatible with the current version and thus not start. You may have encountered a bug in the program.

I do not know if this is a bug or if something has gone wrong with my system.

    This seems to be a bug (see: https://bugs.kde.org/359015). It appears to have been fixed upstream, but not in Ubuntu (at least not in 16.04).

    The fix (present in the above bug report) consists of changing two lines in a perl script (/usr/share/kde4/apps/kio_info/kde-info2html), so it can be easily applied manually. In patch format:
