Problem 1) installing mosquitto

Problem 2)

Attempting to install: sudo apt-get install -y mosquitto-client python3-mosquitto

On Jessie the install all worked.

Can some one please advise me and thanks

What do you see if you run 'aptitude search ~o'

[bonzadog]

What do you see if you run 'aptitude search ~o'

Showed nothing

Install based on https://iotbytes.wordpress.com/mosquitt ... pberry-pi/

BUT I re-formatted the SD re copied stretch and manually (the following commands were in a batch)

mkdir mosquitto
cd mosquitto

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-wheezy.list

apt-get install mosquitto
........
pi@mqtt:/etc/apt/sources.list.d $ netstat -tln | grep 1883
tcp 0 0 0.0.0.0:1883 0.0.0.0:* LISTEN
tcp6 0 0 :::1883 :::* LISTEN

So this now works.

aptitude search ~o still shows no information

But this is the same SD, The same RPi, the img ...I am perplexed to why the mqtt Broker now gets installed

[DirkS]

cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-wheezy.list

Why are you using the wheezy list?
Looking at https://mosquitto.org/2013/01/mosquitto ... epository/ I would have used the one for jessie

And I just had a look at the repo and I think there's actually already a mosquitto repo for stretch.

Yes, I overlooked that wheezy reference. I suppose I should use strech instead of wheezy?

But the was when I installed mosquitto there was no "already installed" message.

How can one see if a install programme is available ..Yoi mention looking at the repo.

Much appeciate you help!

How can one see if a install programme is available ..Yoi mention looking at the repo.

After 'apt update' you can check available packages / versions with apt-cache policy. E.g.

Code: Select all

apt-cache policy mosquitto

Ah, when I tried it, I just installed it from the stock repos.

[DougieLawson]

Ah, when I tried it, I just installed it from the stock repos.

Does that include the recent security fix?

I find it easier to add the Mosquitto repo and install the latest from there.
https://mosquitto.org/2013/01/mosquitto ... epository/
Using
http://repo.mosquitto.org/debian/mosquitto-stretch.list to get the version for Stretch.

[ShiftPlusOne]

Does that include the recent security fix?

No idea, I don't actually use it. I was just checking that there's nothing wrong with the stock repos.

[bingyd]

I have exactly the same problem as bonzadog even when I use the mosquitto-stretch.list.
Any suggestions appreciated

[bullockbob]

+1 for me as well.

Cannot get Mosquitto to install under Stretch as per OP Problem 1.

Why is life so difficult with Linux.

Hi,

There are also problems installing opencv 3.x with stretch, however, I could install opencv 3.2 on the 2017-06-21 version of Jessie.

( 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)

[bullockbob]

I had no problem installing Mosquitto under Jessie either. But Stretch appears to be an entirely different story.

Lucky the RPi is relatively cheap allowing for a test server

[DougieLawson]

Can you folks explain what part of viewtopic.php?p=1201759#p1199879 isn't working for you?

[itzdip]

Results:
It still shows the same thing.

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

Current OS:
I currently have have Raspbian Jessie.

Unix Instructions:
This is what I did as per your instructions:
To use the new repository you should first import the repository package signing key:

wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
Then make the repository available to apt:

cd /etc/apt/sources.list.d/
Then one of the following, depending on which version of debian you are using:

sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list


Then update apt information:

apt-get update
And discover what mosquitto packages are available:

apt-cache search mosquitto
Or just install:

apt-get install mosquitto

PS: Relatively new in this. I am trying to install MQTT broker to use it in Node-Red workflows. Looking forward to your help.

Thank you,
itzdip

Hi there

Exactly as I explained previously, the exact same problem I have is what the OP Prob #1 has/had. I first tried using the jessie list and got the Prob 1 error. Then I tried with the stretch list and got the exact same error (exact same as OP Prob #1).

?

Actual error msg is:

So you'll need to report that to Roger Light on the Mosquitto mailing list.

[DirkS]

Someone opened an issue at https://github.com/eclipse/mosquitto/issues/529

[bullockbob]

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.

If not, any other suggestions for a MQTT broker installed under Raspbian would be helpful as it appears there has been no help on the Mosquitto forum, so maybe it's time to look for alternatives.

Thanks

Yes. But only by installing it on Jessie and upgrading that to Stretch.

https://github.com/eclipse/mosquitto/issues/529

You can build from source.

sudo apt-get install cmake libssl1.0-dev libwebsockets-dev uuid-dev
cd /tmp
wget http://mosquitto.org/files/source/mosquitto-1.4.14.tar.gz
tar xavf mosquitto-1.4.14.tar.gz
cd mosquitto-1.4.14
cmake .
# cmake -DWITH_WEBSOCKETS=ON . if you need websockets support
make -j4
sudo make install

Am I missing some detail in this discussion ?

[DougieLawson]

What version does that get? Is it 1.14? Does it have the websockets support?

[bullockbob]

You can build from source.

sudo apt-get install cmake libssl1.0-dev libwebsockets-dev uuid-dev

Installing from Stretch, this line gives me :

Reading package lists... Done
Building dependency tree
Reading state information... Done
cmake is already the newest version (3.7.2-1).
uuid-dev is already the newest version (2.29.2-1).
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:
libssl-dev : Conflicts: libssl1.0-dev but 1.0.2l-2 is to be installed
libssl1.0-dev : Conflicts: libssl-dev but 1.1.0f-3 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

[DougieLawson]

It worked for me on a fresh install of 2017-08-16 Raspbian.

Try using synaptic or aptitude to do the install for you. They can resolve the conflicts.

Thanks for your time and help. Aptitude did indeed perform an install of Mosquitto from scratch on Stretch. The version installed was several behind current (inc the security patch), but I used your instructions for building from source to update to the current.

Thanks again.
