#cvs.lock error in Emptydir

[Arcin Bozkurt]

This is what I get when doing an update:

cvs server: Updating .
cvs server: failed to create lock directory for 
`/opt/cvsroot/CVSROOT/Emptydir'
(/opt/cvsroot/CVSROOT/Emptydir/#cvs.lock): 
Permission denied
cvs server: failed to obtain dir lock in repository 
`/opt/cvsroot/CVSROOT/Emptydir'
cvs [server aborted]: read lock failed - giving up


What can I do to solve it?

Thanks.
