Bug Description

In a Lubuntu Vivid daily Live Session test (20150109), I tried to access the Help section in file-roller and got the following error message:

Could not display help
The specified location is not supported

Steps to reproduce
1.Boot Lubuntu Vivid live session on USB
2.Open Accessories > "Archive Manager"
3.In main menu, select "Help" > "Contents" (OR press F1)

Expected results: to access the help section for file-roller.

Actual results: A dialog appears and shows "Could not display help"

Install yelp.

This help button does not work. This is because it is intended to launch yelp the gnome help tool which is not in lubuntu-desktop. Installing yelp is a workaround that will get help working. Yelp may have been left out for iso size concerns but this workaround should be documented somewhere.

Installing Yelp workaround tested & works.

Installing Yelp included the following packages:

gnome-user-guide libyelp0 yelp yelp-xsl

apt reported this used 46.0 MB of additional disk space.

Actually, this is not just on a live session. This issue also remains on Lubuntu after it's been fully installed on a new computer.

Same workaround - installing yelp - solves this issue.

Language Support (the language-selector-gnome package) is another tool whose help does not open due to the absence of yelp. Same thing: yelp is recommended, not a dependency.

gnome-user-guide would make up the bulk of that 46MB, and that probably wouldnt even be useful on lubuntu.

Gunnar Hjalmarsson (gunnarhj) wrote :

How about these changes:

- Move gnome-user-guide from recommends to suggests in yelp

- Add gnome-user-guide to recommends in ubuntu-gnome-meta

- Move yelp from recommends to depends in file-roller and language-selector-gnome
