sorry for late reply:
this is the text I used in debian:
hello debian-user,
for those of you who use cacti....
I've prepared some packages of the beta4 release of cacti/spine 0.8.7 (for
spine, i386 and amd64 builds), which are now available for general testing
and feedback. The easiest way to upgrade is to put:
deb
http://people.debian.org/~seanius/cacti/beta ./
into your /etc/apt/sources.list, and run
apt-get update
for users who don't already have cacti installed, they can then do:
apt-get install cacti mysql-server
and to install spine:
apt-get install spine
for users who have cacti (but not cacti-cactid) already installed:
apt-get upgrade
for users who have cacti and cacti-cactid installed:
apt-get dist-upgrade
is needed, to transition from cacti-cactid to the new spine package.
