Installation problem in KNOPPIX 4.0

I've a problem while installing freemind.
I've followed the advises to install it, but when I type freemind, I get the following error message:

Can you help me please?
Thank you

Hi,

it's most probably because you're logged in as non-root in KDE/GNOME/whatever but try to start freemind as root.
Start a console/terminal as normal user and start freemind from there, or use Alt+F2 and type freemind in the popping up window, or find the FreeMind menu point (Knoppix fiddles a bit with the menu but it should be under Debian/Apps/Text).

Last but not least: you've installed freemind 0.7.1 and it's my fault, you should type:
apt-get -s install freemind/experimental
(plus freemind-plugins-help freemind-plugins-svg freemind-plugins-time if you want to install the plugins)

Cheers, Eric

Thanks for your suggestions, but nothing works at all!!!

When I type # apt-get -s install freemind/experimental,
I get this error message:

Reading Package Lists... Done
Building Dependency Tree... Done
E: Release 'experimental' for 'freemind' was not found.

What have I to do?
I've installed again the jre and jdk, but no progress!!!
It's a pity because I need freemind work properly, so I do not use it on XP.

Thank you, for your help!

Hi,

first, did you try to start freemind as normal user and did it work? This should allow you to use freemind 0.7.1 at least (if you are not able to run 0.7.1 there are few changes that you'll be able to run 0.8.0).

second, in order to install freemind 0.8.0, you should first read the release notes under https://sourceforge.net/project/shownotes.php?release_id=355162 and come back here if you have further questions.

Hope this helps, Eric
