The URL is wrong. Yes, trunk exists, but not under code
- it is under MichaelKrebs
.
I used anonymous access to look there:
$ svn ls svn://svn.code.sf.net/p/michaelkrebs/code
MichaelKrebs/
$ svn ls svn://svn.code.sf.net/p/michaelkrebs/code/MichaelKrebs
branch/
tags/
trunk/
$ svn ls svn://svn.code.sf.net/p/michaelkrebs/code/MichaelKrebs/trunk
.htaccess
.project
404.html
crossdomain.xml
css/
images/
includes/
index.php
js/
robots.txt
So, your desired url must be this:
svn+ssh://atrioom@svn.code.sf.net/p/michaelkrebs/code/MichaelKrebs/trunk
