This command only provides information on command line. It does not launch Info Center.
kinfo kinit
When I ran that I saw basic information about my system.
Right clicking on Info Center in the app menu, the command is
kinfocenter
When I ran that, it did bring up the "About this System - Info Center" window. I can also bring it up from the icon in the app menu. Is this the window you expect to see? If not, let us know what you're expecting.
What I would suggest is:
- Check for broken packages and fix if necessary as described in Troubleshooting Common Issues.
- If there were broken packages that were fixed, that may fix the issue. If not, try running
kinfocenter
on command line.
If it still doesn't bring up the window from command line, see if there are errors in your terminal. (Ignore anything about QML MouseArea).
