Overview

apt-dater provides an ncurses interface for managing package updates of multiple hosts.

One master host needs access via ssh to each managed node. Each managed host contains a simple perl-based agent (apt-dater-host).

cron-apt is a good companion for apt-dater - it sends mail notification for pending package updates.

Setup

Master host

aptitude install apt-dater
create a config file listing all managed nodes (.config/apt-dater/hosts.conf):
```
[foo-group]
Hosts=localhost;foo;bar;baz
```

Managed hosts

aptitude install --without-recommends apt-dater-host
- sudo is part of apt-dater-host recommendations - probably you do not need it

Operation

run apt-dater on the master host
the program automatically connects to all listed managed hosts (see config file above) - see the status bar at the bottom of the screen
wait until the list In refresh is empty
hosts are now grouped according to their status
verify the hosts below unknown: press e for further information about their failure (see the bar at the top of the screen)
go through the details of the hosts to be updated (Updates pending)
run the updates via u for each host

apt-dater also helps to keep your hosts' packages in a clean state: all orphaned packages (no longer available in current package sources) are marked with x. Use aptitude or similar tools for cleaning up the mess.
