There surely is a problem ... just how to configure apt(itude) not to update maildrop

Seems like it's un-holding it, and upgradeing it every day

/etc/cron.daily/aptitude is the guilty one

Just removed it

until new maildrop pacakge comes out ... Still can do manual update ...

apt

Code:

#!/bin/sh

# This file understands the following apt configuration variables:
#
#  "APT::Periodic::Update-Package-Lists=1"
#  - Do "apt-get update" automatically every n-days (0=disable)
#    
#  "APT::Periodic::Download-Upgradeable-Packages=0",
#  - Do "apt-get upgrade --download-only" every n-days (0=disable)
# 
#  "APT::Periodic::AutocleanInterval"
#  - Do "apt-get autoclean" every n-days (0=disable)
#
#  "APT::Periodic::Unattended-Upgrade"
#  - Run the "unattended-upgrade" security upgrade script 
#    every n-days (0=disabled)
#    Requires the package "unattended-upgrades" and will write
#    a log in /var/log/unattended-upgrades
# 
#  "APT::Archives::MaxAge",
#  - Set maximum allowed age of a cache package file. If a cache 
#    package file is older it is deleted (0=disable)
#
#  "APT::Archives::MaxSize",
#  - Set maximum size of the cache in MB (0=disable). If the cache
#    is bigger, cached package files are deleted until the size
#    requirement is met (the biggest packages will be deleted 
#    first).
#
#  "APT::Archives::MinAge"
#  - Set minimum age of a package file. If a file is younger it
#    will not be deleted (0=disable). Usefull to prevent races 
#    and to keep backups of the packages for emergency.

Hi, I moved /etc/cron.daily/aptitude to another folder and maildrop is still getting updating every day. Is there a service that needs to be restarted after removing the /etc/cron.daily/aptitude ?

thx

This is becoming a pain in the ass. If I forget to run the downgrade everyday, my client calls bitching....man there has got to be a way to stop this. Anyone know how I could put a script to run every morning that would run the downgrade?

StrikerNL · #35 15th February 2010, 11:20

I have this same problem on Ubuntu 9.04. I hid the maildrop package upgrade for now, but it would be nice if it worked.

Also, I hope this won't prevent me from upgrading to Ubuntu 9.10 at some point.
