Nginx+PHP-FPM - Apache gets installed automatically on PHP update

[Benjamin Tegge]

[Status]

Cannot reproduce. This bug will not make any progress until someone affected can provide exact and detailed steps to reproduce the problem from a fresh Ubuntu Server installation or cloud image.

[Original Description]

This was originally posted as a question. See: https://answers.launchpad.net/ubuntu/+source/php5/+question/250691
---

My 14.04 machine that runs Nginx with PHP-FPM received updates for PHP and somehow Apache was automatically installed.

Here is an excerpt from APT history log:
Install: libapache2-mod-php5:amd64 (5.5.9+dfsg-1ubuntu4.1, automatic), libaprutil1-dbd-sqlite3:amd64 (1.5.3-1, automatic), libaprutil1-ldap:amd64 (1.5.3-1, automatic), apache2-data:amd64 (2.4.7-1ubuntu4, automatic), apache2:amd64 (2.4.7-1ubuntu4, automatic), apache2-bin:amd64 (2.4.7-1ubuntu4, automatic)

Looking at the dependencies for the php5 package I don't understand why this happened:
Depends: libapache2-mod-php5 (>= 5.5.9+dfsg-1ubuntu4.1) | libapache2-mod-php5filter (>= 5.5.9+dfsg-1ubuntu4.1) | php5-cgi (>= 5.5.9+dfsg-1ubuntu4.1) | php5-fpm (>= 5.5.9+dfsg-1ubuntu4.1), php5-common (>= 5.5.9+dfsg-1ubuntu4.1)

With Nginx configured to listen on port 80, this unwanted Apache installation would interfere at startup (this exactly happened sometime ago on an older release). I don't think that this behaviour is correct.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Please could you expand on this? How exactly did you receive updates?

Once you've explained, please change the bug status back to New. Thanks!

I ran apt-get update and apt-get dist-upgrade on the machine, the apt history excerpt shows that new packages that got installed during this event. php5-fpm is from the repositories and nginx-extras from https://launchpad.net/~nginx/+archive/development.

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks to Brian Murray for the ping on IRC (in #ubuntu-bugs). This is not an nginx PPA problem.

There have been no NGINX package updates in that repository since February 10, 2015. The NGINX PPA also has ***zero dependencies, recommends, or suggests*** on php5-fpm or any other PHP or Apache components. This is not an issue with the third-party packaging of NGINX as done by myself.

This remains an issue unrelated to the third-party-packages.

[Thomas Ward (teward)]

I've also done some testing in a system with nginx and php5-fpm installed - nginx from the (stable) PPA, and php5-fpm from the repositories, on a Trusty system. This is in a production environment, on a VPS from RamNode, and the php5-fpm and nginx haven't been updated in a while (at least three months).

Attached is a logfile from a dry-run of the `apt-get dist-upgrade --dry-run` and that there are no apache2 packages (other than apache2-utils which I use to generate htpasswd compatible items for nginx, and can exist separately from the apache2 binaries). (This shows it's not an nginx problem, nor does it appear to be a php5 problem, and that this needs to be dug into more deeply to identify potential causes.)

[Thomas Ward (teward)]

NOTE: I do not have the `php5` metapackage installed on this server - I explicitly installed php5-fpm WITHOUT the `php5` metapackage. I only have the `php5-fpm` package (and related dependencies) installed. Is it at all possible that the `php5` metapackage ignored the dependencies list and therefore installed Apache because it couldn't see that php5-fpm is existing?

[Thomas Ward (teward)]

Can anyone confirm whether this happens with the `php5` metapackage actually in the 'installed' state prior to the update, or whether this happened with only `php5-fpm` installed?

We also need more steps to reproduce this before we can more thoroughly start examining and testing.

[Jacek (Hyacinth) Stypuła (js-ubuntuone)]

Today, with `php5` security updates again I have got `apache2` installed as a bonus.

I had `php5` metapackage installed prior to the update, so it may be the culprit.
