DreamTracInstall.sh MySQL problems


I’m trying to use the DreamTracInstall.sh but the installation always fails at the last step:

Thank you for choosing Trac 0.10.4. Enjoy your stay!

I’ve checked, double-cheked and triple-checked all the values asked by the script. I can access the MySQL host without problems using a web browser. I’m already using MySQL for several other databases, so I know that it’s working properly. Same thing for the Subversion server. Any hints for solving the problem are most appreciated. Searching the forums and the wiki have not resulted so far in useful information for solving this problem.

All the best,


P.S. Yes, I’ve already voted for a one-click install of Trac.
