I'm currently self compiling the nginx package using the following:

sudo apt-get build-dep nginx-extras
sudo apt-get install build-essential
apt-get source nginx-extras
cd nginx
<add some custom module here>
dpkg-buildpackage -us -uc
sudo dpkg -i nginx-extras_1.10.0-0ubuntu0.16.04.4_amd64.deb
sudo apt-mark hold nginx-extras

I do this because I need to install some custom modules - however after running this, apt-get upgrade indicates there is an upgrade for nginx that it would apply if apt-mark hold were not in effect. I thought I just compiled the latest version, so why does it want to upgrade??

The problem I have here is that I use apticron which sends me an email each day indicating I have unupgraded packages when I in fact do have the latest.

EDIT: Some additional output:

$ sudo apt-get upgrade --simulate

  • What's the output of apt-cache policy nginx-core and apt-get upgrade --simulate? – David Foerster Apr 2 '17 at 23:51
  • @DavidFoerster updated question with info – Martin Konecny Apr 3 '17 at 0:48
  • nginx-extrasnginx-core. Please supply the correct command output. Also, why do you install one package (nginx-core), tell Apt to hold back another (nginx) and expect the former to be held back? – David Foerster Apr 3 '17 at 3:07
  • Sorry, please take a look at the revised question. I actually have nginx-extras installed (which conflicts with nginx-core) – Martin Konecny Apr 3 '17 at 15:27

You can override the check with an apt preference. For example (change release as applicable): Create in /etc/apt/preferences.d/nginx-custom

Package: nginx
Pin: release n=yakkety
Pin-Priority: -1

# This will cause nginx to be ignored and use the locally compiled version only

I use this technique with a custom ffmpeg compilation similar to your nginx need.

  • I believe this would completely disable updates? I'd still like apt-get upgrade to inform me when my self-compiled version is now out-of-date and potentially insecure. – Martin Konecny Apr 3 '17 at 0:49
