Hi all,

I'd like to mirror all the packages installed in a production server with
the
same versions. The idea is to have a enviroment test the upgrades before
apply
those upgrades to the real production server. What is the best way to do
this?

Thank you very much


You can do something like this:
on the current machine:
sudo dpkg --get-selections > server.selections

then copy the server.selections file to your test machine and run:
sudo apt-get update
sudo dpkg --set-selections < server.selections
sudo apt-get dselect-upgrde


That will install all packages that are on your current server on your
test server.

I like this option more than the one proposed François. Will this install
the same versions I in the production server?


Thanks


Assuming of course that you have the same sources listed in
/etc/apt/sources.list , in regards to stable/testing/sid. So, if both
machines are etch, then all packages will be the same version. But, this
will only upgrade packages installed through apt/aptitude. Any packages
that have been installed by hand wont be upgraded.
