Issues after upgrading to 16.04

Tom

So I followed the steps 1-6, when running the installer, apache is failed to install.

When trying to install apache2 , I get broken package.

Frustrating!!

@Tom Did you try the commands I talked about earlier.

sudo apt purge php*
sudo apt purge apache*
sudo rm -rf ‘/etc/apache*’ ‘/etc/php*’
sudo apt-get autoremove

Along with the #COMMENT out the entire PACKAGES LINE in fogsettings. So in front of the entire line. (#PACKAGES)

I know you have probably done this too but make sure all is updated.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

I would also make sure you have all the updates release info.

sudo do-release-upgrade.

Once this has all been done then reboot (sudo shutdown -r now) and rerun the ./installfog.sh and see what happens.

Tom

@EAHarvey I’ve done it all, once apache2 got broken, I could not fix it.
Thanks!

@Tom Please put the output of

dpkg --get-selections | grep hold

So - I just spun up a brand-new Ubuntu 16 Server VM, updated it, and installed RC-10 on the first try with zero problems.

We typically warn people against upgrading Linux Distributions to another newer major version for use with FOG. It never goes well, this is a good example of why we recommend against it.

I’m going to guarantee that your problems are either being caused by imperfections in the upgrade process from 14 to 16, or by grandfathered-in settings, or by PHP 5.x being mixed with PHP 7.x

All the below instructions assume you are root - proper. Become root properly first with:
sudo -i

Along the lines of what @EAHarvey said about updating, I’d recommend running this line to do that, it’s a more aggressive version that will also clean out things that aren’t needed too.
apt-get update -fy;apt-get upgrade -fy;apt-get dist-upgrade -fy;apt-get autoremove

The next thing to try is simply running the commands the installer would run, but manually. These are them, just copy/paste and give us the results:

a2enmod php
a2enmod rewrite
a2enmod ssl
a2ensite "001-fog"

The next thing to try is deleting the .fogsettings file and then forcing the installer to use PHP7 as we used to do when we had issues with Ubuntu 16, Do that with these commands:

#Go to your fogproject repo's bin directory first#
rm -f /opt/fog/.fogsettings
apt-get purge php*
apt-get purge apache*
rm -rf ‘/etc/apache*’ ‘/etc/php*’
apt-get autoremove
php_ver='7.0' php_verAdds='-7.0' ./installfog.sh -y

Here’s some of my configuration files from Ubuntu 16, does yours look like this? If you run each of the commands in red, it’ll output the file.

cat /etc/apache2/sites-enabled/001-fog.conf

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#	/etc/apache2/
#	|-- apache2.conf
#	|	`--  ports.conf
#	|-- mods-enabled
#	|	|-- *.load
#	|	`-- *.conf
#	|-- conf-enabled
#	|	`-- *.conf
# 	`-- sites-enabled
#	 	`-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.

# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);

# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be

@Wayne-Workman Thank you so much. I had to revert back to 14.04 since I could not leave it non functional - we use it on a daily basis.
I would really appreciate if it can be summarized into one simplified (as possible) list of steps that will result in successful upgrade. It feels like the more I try to fix it, it gets further away from success.

Would it be easier to backup all fog settings and images, build new 16 server, install fog and restore?

If none of this is possible, I will try again using your recent instructions.

Again, thank you all for being out there supporting…

Tom

Wayne Workman

@Tom I’d suggest staying on 14.04 - and moving to FOG Trunk.

Tom

@Wayne-Workman I think I’m on FOG trunk 1.3 RC10.
Thanks!

Wayne Workman

@Tom Then you’re good to go.

Tom

@Wayne-Workman The question is what should I do when I will need to upgrade to new OS. I’m not looking to stay on 14.04 forever
Is there a way to export\import fog settings and images?

Wayne Workman

@Tom Build a new server (use the same IP), install the latest FOG RC or release on it, and port over images and hosts. Copying over images is a simple six-command pow-wow. Getting image definitions and hosts is through the web interface. Host Management -> export, Image Management -> Export, and import on the new server. Then just moving over the certificates and all done.

Just change the old fog server’s IP address at CLI, imaging won’t work on it after this, but it’s fine. The new server shoud be given the old one’s IP address.

From the newly built server with FOG installed, just mount the old server’s images directory to a local directory and then copy them over.

mkdir /tempMount
mount x.x.x.x:/images /tempMount
cp -r /tempMount /images
umount /tempMount
chown -R fog:root /images
chmod -R 777 /images

Follow instructions here for moving your ssl stuff over to the new server - this is very important if you use the new FOG Client.
