[Evolution] Need Help How to configure Synaptic to get current Evolution

[adg adg82439 <adg82439 live de>]

Hi,

I am looking for Help about Packet Sources for the current Evolution,
because Debian which I use has only very old version.

How can I find out what to set in Synaptic to get always the up to date
stable Evolution Version and its updates?


If anyone could help would be very nice.

Thanks in advance

Jo
