Hi Dan,

Thanks for reply , but it do not work.

$ bzr upgrade  lp:rvtk
Format <RepositoryFormatKnit1> for
lp-140211244:///~benlau/rvtk/trunk/.bzr is deprecated - please use
'bzr upgrade' to get better performance
bzr: ERROR: The branch format Bazaar-NG meta directory, format 1 is
already at the most recent format.

(I am using bzr 1.5)
