# Ubuntu – How to hold Ubuntu point release version

For reasons of 3rd party software compatibility I would like to install ubuntu 14.04.1 and hold on version 14.04.1 until such time as I allow upgrade to 14.04.2, 14.04.3 etc…

I have read the ubuntu pinning instructions and looked at the two similar Ask Ubuntu questions pertaining to package holding but i don't see a clear manner of doing this:

the-following-packages-have-been-kept-back-why-and-how-do-i-solve-it

how-to-prevent-updating-of-a-specific-package

The best thing I can see is this neat way of holding everything back:

Save state:

dpkg --get-selections > current_selections.txt


Hold all packages:

dpkg --get-selections | sed -r "s/\tinstall/hold/" |dpkg --set-selections


Revert to unheld packages at some point in the future:

dpkg --set-selections < current_selections.txt


However this seems a bit excessive much, I'd like to carry on running apt-get update && apt-get upgrade and receiving updates for all packages except for those that constitute the upgrade from version 14.04.1 to a later point release.

Is this mad of me, is this counter to the spirit of using apt-get upgrade and Ubuntu's philosophy of point releases as pertaining to LTS versions, (if so why the heck are there point releases to LTS releases which break compatibility with other software, aren't they supposed to be stable and reasonably static targets?)

It also occurs to me that perhaps holding the kernel at the version on 14.04.1 (3.13.0-32) would do the trick as the rest of 14.04.2 and higher will be dependent in the newer kernel. I also have a hunch that it's the later kernel that's borking the software I'm using although the vendors docs aren't specific and i haven't got an answer from them about this.

For clarity, I'd like to add that i do not currently know where the source of incompatibility is between the software I am running and Ubuntu releases >14.04.1 Just that this is what I have been told by the vendor and this does appear to be the case. Whilst i get to the bottom of where these incompatibilities lie, I'm after a way that will allow me to remain on 14.04.1 whilst updating packages that don't constitute a move to anything >14.04.1. If the anwer to this is you can't that's fine, I'd just like to know.

TL:DR

1) How can I hold Ubuntu at version 14.04.1 and prevent upgrade to 14.04.2 or 14.04.3 whilst retaining the ability to apply updates to my packages.

2) Am I misunderstanding Ubuntu LTS strategy and point releases by expecting point releases not to change things dramatically enough to break compatibility

3) Can I achieve my aim by holding the kernel on the 14.04.1 (3.13.0-32) version, and is this sane?

Thanks.
