Re: STRECH and MQTT

Thu Sep 07, 2017 6:29 pm

Dear all

I have the identical problem as the first posting here. This is on a clean install of Raspbian Stretch. The only software loaded beforehand was NodeRed. I used: sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list.

I looked at Aptitude but was not sure if either of the references from a search on Mosquito were correct.

The issue on the mosquitto GitHub does not have any assignees so not sure how quickly a solution will be found.

Response to apt-cache policy mosquitto is:

mosquitto:
Installed: (none)
Candidate: 1.4.12-0mosquitto1
Version table:
1.4.12-0mosquitto1 500
500 http://repo.mosquitto.org/debian stretch/main armhf Packages
1.4.10-3 500
500 http://mirrordirector.raspbian.org/raspbian stretch/main armhf Packages


So would appreciate thoughts on the best approach to get Mosquitto running. Would be great if I don't have to start from scratch (again).

It would be beneficial if you post *your* exact error messages.

The main problem is that the package I find on the repo you refer to, depends on the "libssl1.0.0" package, but both current versions of Debian and Raspbian call the package "libssl1.0.2". It doesnt matter what version number is inside the package if the name is wrong.

If you are the adventurous type you can actually fix this yourself.

Code: Select all

# get the deb-file with wget or copy it from "/var/cache/apt/archives"
wget http://repo.mosquitto.org/debian/pool/main/m/mosquitto/mosquitto_1.4.14-0mosquitto1~nows1_armhf.deb

#extract package
mkdir tmpdeb
dpkg-deb -R mosquitto/mosquitto_1.4.14-0mosquitto1~nows1_armhf.deb tmpdeb

#Fix wrong dependency
nano tmpdeb/DEBIAN/CONTROL
# Now change "libssl1.0.0" to "libssl1.0.2" on the line that starts with "Depends:"
# Save and exit.

# Rebuild
dpkg-deb -b tmpdeb mosquitto_fixed.deb

# Install
sudo dpkg -i mosquitto_fixed.deb
There are probably the same error in the other packages that are available from that repo, but at least the server itself does not seem to depend on them.

EDIT:
I just realized that "nows" stands for "no websockets". And looking here ( http://repo.mosquitto.org/debian/pool/main/m/mosquitto/ ) I find no v1.4.14 version for Stretch with websockets. That might be because the version of libwebsockets in Stretch is "libwebsockets8" and the one in Jessie was "libwebsockets3".. idk..

Thank you for your quick reply. I will give this a go, and also change the libwebsockets dependency from 3 to 8. For reference my error messages were:

pi@home:/etc/apt/sources.list.d $ sudo apt-get install mosquitto

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
mosquitto : Depends: libssl1.0.0 (>= 1.0.1) but it is not installable
Depends: libwebsockets3 (>= 1.2) but it is not installable

Success - but a bit of a bumpy ride! I hope the trail below will useful to others to also get mosquito working on Stretch. However a couple of points:
I wget the version 1.14.12 as this is what was showing as Candidate earlier.
The .deb file was downloaded to root so I did not need the mosquitto/mosquitto/ in the dpkg-deb -R instruction
I ended up editing the control file in leafpad.
The first install failed as I did not have libwebsockets8 installed. So do a:

Code: Select all

apt-cache policy libwebsockets8
first and install if required.

see my install of libwebsockets8 below that also failed but was fixed with

Code: Select all

sudo apt --fix-broken install
Now to my trail. See at the end checks for both mosquito installed and mosquitto stop/start.

Thank you for your help. Very nice to have this sorted and without starting from scratch! I find the Pi a big trial and am most grateful for the advice. Assembly code on PICs is a piece of cake compared to this.

I can now get on with gaining some C experience getting MQTT working with some ESP8266s.

Perhaps that works but according to

So, mosquitto is there and available to be installed.

my install is based on https://iotbytes.wordpress.com/mosquitt ... pberry-pi
BUT I did find that if I do not execute:
cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list #

sudo apt-get install -y mosquitto worked.
......
sudo apt-get paho-mqtt

Perhaps I am missing a more up to date install information

I am not convinced the install after editing the dependency file has worked.

First I have a Sonoff switch with the Tasmoda firmware loaded and logged on to my network. It reports:

14:00:26 MQT: Attempting connection...
14:00:27 DNS: Query done. MQTT services found 0

I then checked mosquito was running and tried mosquitto - v - that gave an error:

Code: Select all

pi@home:~ $ sudo /etc/init.d/mosquitto stop
[ ok ] Stopping mosquitto (via systemctl): mosquitto.service.
pi@home:~ $ sudo /etc/init.d/mosquitto start

pi@home:~ $ mosquitto -v
mosquitto: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
I then tried to subscribe and publish and got command not found:

Code: Select all

pi@home:~ $ mosquitto_sub -d -t hello/world
-bash: mosquitto_sub: command not found
pi@home:~ $ mosquitto_pub -d -t hello/world -m "Hello from Terminal window 2!"
-bash: mosquitto_pub: command not found

Any help would be much appreciated.

You could go to the directory /usr/lib/arm...somethinhsomthing and make a symbolic link from the libssl.so.1.0.2 file to the name its looking for.

Sorry I have had enough getting nowhere. I have gone back to square one, loaded jessie and am now able to do coms from mosquitto to an ESP loaded with Sonoff-Tasmota so I can concentrate on IoT rather than Linux. It is time for someone else to take up the mantle of getting mosquitto on Stretch. When I see a solution, and others confirming it works then I will have another go. This has been three days of frustration. I think this is enough. Mike

It was more of a quick intro guide, but yes, it worked (as can be seen on the post - nothing edited) on a fresh card install and apt upgraded before MQTT software installation.

Does anyone actually have the Mosquitto broker installed and running under Stretch? If so, can they detail their exact steps for the installation process? That would be really helpful.
Clean Raspbian Stretch 2017-09-07 install, sudo apt-get install mosquitto worked for me. Also install the mosquitto-clients package for easy testing.

sudo apt-get update ; sudo apt-get dist-upgrade should work if your initial install was Stretch, if you installed third party repos or have upgraded from Jessie, all I can say apt is very good, but a long way from perfect.

My Jessie machines that I've upgraded to Stretch (edit /etc/apt/ files, run apt-get update, apt-get dist-upgrade) have a working copy of Mosquitto.

It doesn't look like the issue with the install https://github.com/eclipse/mosquitto/issues/529 is resolved (there's lots of "me too"'s but no sane response from the developers).

Of course other MQ brokers are available (that can handle the MQTT protocol) if Mosquitto is broken.

Bonzadog,

I just noticed this in an earlier post:
(I got a few PM regarding the name. Bonzadog was an original English Group in the 1960's. Their full name was Bonza Dog Doo Dah Band)
Actually the band was "The Bonzo Dog Doo-Dah Band" also known as "The Bonzo Dog Band". Or for us just "The Bonzos"

I have now loaded Mosquitto on both Jessie and Stretch.

In the case of Jessie I used the following code before install:

Code: Select all

sudo wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
cd /etc/apt/sources.list.d
sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list
I was able to install mosquito, mosquitto clients and python mosquitto.

Code: Select all

sudo apt-get update
sudo apt-get install mosquitto mosquitto-clients python-mosquitto
This delivered Mosquitto version 1.4.14

The repo list for Stetch did not enable install.

So I just used apt-get.
python-mosquitto did not install - so only able to do:

Code: Select all

sudo apt-get update
sudo apt-get install mosquitto mosquitto-clients
This delivered Mosquitto version 1.4.10

Stretch also had a later version of Node Red (0.17.4 vs 0.15.3 for jessie)

So in conclusion it appears that one has a choice or either

Jessie+Mosquitto 1.4.14+Node Red 0.15.3+ mosquitto clients and python-mosquitto

or:

Stretch + Mosquitto 1.4.10+Node Red 0.17.4+mosquitto clients but not python-mosquitto.

AFAIK python-mosquitto was original method of coding MQTT stuff in Python and was superceded a while ago by paho-mqtt which is installed using pip

You are not wrong. Although looking at the sample code, it's largely a re-packaging exercise.

Re: STRECH and MQTT

I also got the missing libssl1.0.0 error and found the following fix :

Code: Select all

wget http://security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u6_armhf.deb
sudo dpkg -i libssl1.0.0_1.0.1t-1+deb8u6_armhf.deb
after this you can install mosquitto and mosquitto-clients :

Code: Select all

sudo apt-get install mosquitto
sudo apt-get install mosquitto-clients

You can add the necessary packages then install Mosquito

cd ~
wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list
sudo apt-get update

cd ~
wget http://security.debian.org/debian-secur ... _armhf.deb
sudo dpkg -i libssl1.0.0_1.0.1t-1+deb8u6_armhf.deb
wget http://ftp.nz.debian.org/debian/pool/ma ... _armhf.deb
sudo dpkg -i libwebsockets3_1.2.2-1_armhf.deb
sudo apt-get install mosquitto mosquitto-clients

Under what circumstances would that be necessary, given that in the preceding post @asandford appears to demonstrate that a simple

Code: Select all

apt install -y mosquitto mosquitto-clients
was sufficient.

Its well hidden in the thread but I believe the main goal of this thread (at start at least) was to install a newer version ( 1.4.14+) than the one in the stock repos ( 1.4.10 ).

That might be a stretch-goal (no pun intended), but the OP makes no mention of that:

On Jessie the install all worked.

Can some one please advise me and thanks

They couldn't get stock mosquitto to work.

If others have hijacked the thread to install a 'non-supported' version, then that's their problem and they should do a new post.
