Problems updating to WordPress 2.8 using SVN

If you’re like me, you run your WordPress installation off of a SVN checkout, making it far easier to stay up to date with new versions. In fact, using version control checkouts is an excellent way to maintain web applications running on production servers, especially if they don’t require compilation.

However, if you recently tried to upgrade to the latest version using the instructions at the WordPress Codex, you likely ran into a problem with an error mesage like this:

$ svn sw http://core.svn.wordpress.org/tags/2.8/ . 
svn: 'http://core.svn.wordpress.org/tags/2.8/'
is not the same repository as
'http://svn.automattic.com'
