Failed to initialize environment. ("Expected format '3' of repository; found format '5'", 165005)

While attempting to configure trac, I observed the following error:

[trac@kenny ~]$ sudo trac-admin /home/trac/env initenv
Creating a new Trac environment at /home/trac/env

See the brand new TracSubversion#Troubleshooting section. In this case, this is a duplicate of #3943.

What about a wiki page like TracTroubleshooting that serves as a central place to provide troubleshooting solutions for all kind of issues?

[Christian Boos]

Or maybe a better visibility of the already existing troubleshooting sections from the TracFaq, as it's already one of the starting point… Otherwise you're just adding another intermediate level (which, acting as a kind of central index for troubleshooting, has its merit, but better use the TracFaq for that).
