[silvio.fricke@…]

First: Sorry for the bad english!

I use trac from svn and have version 5198

As root i drop of a commandline:

# trac-admin ./sv-studio initenv

This results in:

Which string did you specify for the DB string?

Database connection string [sqlite:db/trac.db]>

Have you updated from a previous release, is there any other Trac environment installed on your machine?

[silvio.fricke@…]

Which string did you specify for the DB string?

Database connection string [sqlite:db/trac.db]>

I have specified 2 DB-strings:

• 1st: only press <RETURN>
• 2nd: because the error I have typed "​sqlite:db/trac.db"

Have you updated from a previous release, is there any other Trac environment installed on your machine?

No updated or previous installation of trac.

[silvio.fricke@…]

I have still the same error.
(git-changeset: genshi: 562, trac:5292) Now I have included a trac-strace.

Did you ever resolve this problem?

[silvio.fricke@…]

No!

I get the same error.

Creating a new Trac environment at /home/silvio/TRAC/testrepo-trac

Trac will first ask a few questions about your environment 
in order to initalize and prepare the project database.

 Please enter the name of your project.
 This name will be used in page titles and descriptions.

Project Name [My Project]> testrepo

 Please specify the connection string for the database to use.
 By default, a local SQLite database is created in the environment 
 directory. It is also possible to use an already existing 
 PostgreSQL database (check the Trac documentation for the exact 
 connection string syntax).

Database connection string [sqlite:db/trac.db]> 

 Please specify the type of version control system,
 By default, it will be svn.

 If you don't want to use Trac with version control integration, 
 choose the default here and don't specify a repository directory. 
 in the next question.

Repository type [svn]> 

 Please specify the absolute path to the version control 
 repository, or leave it blank to use Trac without a repository.
 You can also set the repository location later.

No, it's not: search:"database parameter must be string or APSW Connection object"

i.e. for your problem, see #6585.

Not reproducible, closing.
