Ability to do and unattended do-release-upgrade about debops-playbooks

[drybjed]

Good idea. I actually have a playbook that would do this - switch all APT sources from wheezy to jessie. Then an automatic apt dist-upgrade could be performed as an optional step. I'll look for it and include in the tools/ directory.

Would this be the right way to handle this rather than running do-release-upgrade? -- do-release-upgrade deletes obsolete libraries and I'm guessing a bunch of other cleanup?

@Hackeron Sure. It's just that do-release-upgrade is Ubuntu specific. :-) I can look into using it on Ubuntu systems, of course.

No do-release-upgrade for ubuntu users? :(

@Hackeron I'm not sure yet how exactly it works. I'll check on a spare Ubuntu VM first, unless you maybe know if it operates non-interactively and leaves the system in a workable state?

In my script I run:

apt-get install update-manager-core
do-release-upgrade -f DistUpgradeViewNonInteractive

To ensure it doesn't ask any questions :)

@Hackeron do-release-upgrade steps are described in this AskUbuntu post. What I see is that do-release-upgrade basically does the same thing (and more) as the dist-upgrade.yml playbook. :-)

Are above commands all the steps you need to do the upgrade?

Yep, it seems to be quite good at removing anything obselete :) - yep, the above steps is what I've used for years and it never fails to update and it never asks any questions with "-f DistUpgradeViewNonInteractive" :)

@Hackeron In that cast most of dist-upgrade could be discarded for Ubuntu... Does do-release-upgrade have any output to capture and send to the admin?

What do you mean discarded? - it seems to do quite a lot of useful stuff. Yes, it gives the output from everything it does, like running apt internally, etc.

@Hackeron do-release-upgrade handles APT sources, runs apt-get update, upgrades packages, removes APT preferences for backports... All you would be interested in is probably the last task which sends an email with output to administrator. :)
