Permission denied error trying to commit to Subversion

I can checkout but I can't checkin

The开发者_运维百科 error is svn: Can't open file '/Users/Shared/svn/test/db/txn-current-lock': Permission denied

What can I do to fix this

Are you in the same group as the owner of the files in the svn repository directories ? Are the files group writable ?

have you tried doing the command "svn cleanup" sometimes it helps with random svn problems
