This installed perfectly I think, but did not install the webserver software required to use the program. I found the source code is available and can be installed, but the website redmine.com is now a placeholder. There are some websites and youtube videos showing how to use RedMine that are helpful, and they will also cover how to install the webserver on your linux mint or linux ubunty system as well. There is a lack of support from the originators of RedMine and this is confusing to me. Have found another fork or replacement to redmine called "EasyRedMine" which seems to be a very well supported pay to use licenced version which I suggest people explore. Date of Comment - Dec 2017
I think more people should be using this!
