Not feeling the joy yet.
So Ubuntu 16.04 LTS and Discourse don’t play well, or I’m doing it wrong, or I’m not worthy.
I followed the steps documented here/above among countless wiki, but I’ve narrowed the search to a couple basic sites that seem to have it sorted. My attempt, utter failure:
To summarize:
# wget -qO- https://get.docker.com/ | sh
yields:
modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/3.10.23-xxxx-std-ipv6-64/modules.dep.bin'
modprobe: FATAL: Module aufs not found in directory /lib/modules/3.10.23-xxxx-std-ipv6-64
Warning: current kernel is not supported by the linux-image-extra-virtual
package. We have no AUFS support. Consider installing the packages
linux-image-virtual kernel and linux-image-extra-virtual for AUFS support.
+ sleep 10
Oh, by the way, which linux-image* packages are installed?
# apt list --installed | grep linux-image
linux-image-4.4.0-45-generic/xenial-updates,xenial-security,now 4.4.0-45.66 amd64 [installed,automatic]
linux-image-extra-4.4.0-45-generic/xenial-updates,xenial-security,now 4.4.0-45.66 amd64 [installed,automatic]
linux-image-extra-virtual/xenial-updates,xenial-security,now 4.4.0.45.48 amd64 [installed]
linux-image-generic/xenial-updates,xenial-security,now 4.4.0.45.48 amd64 [installed,automatic]
linux-image-virtual/xenial-updates,xenial-security,now 4.4.0.45.48 amd64 [installed]
Trying to be pin-point accurate as I’ve seen in other wiki articles:
# apt-get install linux-image-virtual kernel-$(uname -r)

This Ubuntu 16.04 LTS is
Welcome to Ubuntu 16.04.1 LTS (GNU/Linux 3.10.23-xxxx-std-ipv6-64 x86_64)
What’s in /lib/modules
?
drwxr-xr-x 5 root root 4096 Oct 20 14:31 4.4.0-45-generic
Well I could probably explore why the difference between uname -r and the modules under version 4.4.0…
Anyway,… I killed that right there. Something afoot at Circle K.
I can install Docker another way – which seems to pass successfully (Applied Step 1 only to the URL below)

After that maneuver, I can get this:

About the system:
# uname -a
Linux foo 3.10.23-xxxx-std-ipv6-64 #1 SMP Tue Mar 18 14:48:24 CET 2014 x86_64 x86_64 x86_64 GNU/Linux
So at any rate, let’s try to make a container:
(Manually created the app.yml due to the fact the default setup doesn’t have a workaround if there’s already Apache listening on port 80. For what it’s worth I got Apache primed and ready for the container once it’s setup. So copied the standalone.yml and replaced “example.com” with the domain in question, and other port number shenanigans)
Off topic - the Apache config for the server in question (domain names changed to protect the guilty)
<VirtualHost *:80>
ServerName foo.net
DocumentRoot /whatever/foo
ErrorLog /var/log/apache2/foo-errors.log
<Directory /whatever/foo>
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
ProxyPreserveHost On
ProxyRequests off
ProxyPass / http://127.0.0.1:7654/
ProxyPassReverse / http:/127.0.0.1:7654/
</VirtualHost>
Now that the app.yml is hand-edited for simply referring to the domain and port numbers (7654) as per countless wiki articles:
The response:
# ./launcher bootstrap app
/usr/bin/docker: Error response from daemon: failed to create endpoint compassionate_stonebraker on network bridge: failed to add the host (vethe5fcb14) <=> sandbox (vethe7f312f) pair interfaces: operation not supported.
Your Docker installation is not working correctly

So, I’m a bit perplexed:
Does Ubuntu 16.04 LTS work with Discourse? If so, what changes do I need to make in the installation process to overcome this. I’m either doing it wrong, or I’m just not worthy. Let me know…
Thanks
