Hi All,

Just want to report the install warning below. Not sure if it's known issue
but it is a disconcerting message.







*The following NEW packages will be installed:  fonts-dejavu libtk-img
pd-extended tcllib tkdnd ttf-dejavu ttf-dejavu-extra0 to upgrade, 7 to
newly install, 1 to remove and 5 not to upgrade.Need to get 40.5 MB of
archives.After this operation, 104 MB of additional disk space will be
used.Do you want to continue? [Y/n] yWARNING: The following packages cannot
be authenticated!*

cheers
Richie
