I try to migrate a trac installation from a debian wheezy server to another debian jessie.

If I copy all files to the new server I get the message, that I have to upgrade with trac-admin /var/trac/blimus upgrade, which seems to work, but it seems not to update all plugins.

for example I had a plugin installed in the old trac, that lets you login on a webpage instead of the htaccess popup.

On the new server I now get the error

Error: Not Found
No handler matched request to /login

How do I get the web-login back?

Is there a way to analyze the old trac folder, which plugins were installed, so I can install the missing ones in the new installation?

I checked the new trac.ini file and added the missing options, this is my trac.ini

These are my versions:

# trac-admin --version          
Warning: Detected setuptools version 5.5.1.
Welcome to trac-admin 1.0.2

This instruction will work on Debian jessie (Trac 1.0.2), as well as Ubuntu 14.04 trusty (Trac 1.0.1)

Prerequisites

On your old Debian wheezy server:

# cd ~/
# tar -cvzf trac-example.tgz /var/trac/example
# cp /var/trac/example/conf/trac.ini trac.ini-example
# update your trac.ini-example to match new settings

Installation on the new server

#!/usr/bin/env bash
