Help installing mosquitto

Configuration
1

Hi

I’m trying to follow the BRUH tutorial on installing mosquitto but my lack of linux knowledge means I’m hitting a brick wall at step 1.

When I try to install it says I’m missing ‘libwebsockets3’. I tried to remedy this by asking it to install libwebsockets3 but perhaps I didn’t format my request right or something.

Anyway here is what I have been putting into terminal, any suggestions much appreciated!

The following information may help to resolve the situation:

edit: fixed formatting

Always update your apt before hitting install. (have you edited your sources.list?

sudo apt-get update
3

This is likely to be the problem. It should be called /etc/apt/sources.list.d/mosquitto-stretch.list and contain

deb http://repo.mosquitto.org/debian stretch main

Which tells apt-get to fetch the file from the mosquitto archives, rather than the debian archives. The debian archives seem to have problems for mosquitto at the moment.

edit: See this link for reference Redirecting...

Thanks I had run apt-get update before I tried.

I’m not sure how edit sources.list soi presume I haven’t

5

Thanks - I read through that link and tried to follow the instructions but it didnt work.

The last comment in that thread says:
This page needs an update for Debian/Raspbian Stretch.

/etc/apt/sources.list.d file to fetch with wget is http://repo.mosquitto.org/debian/mosquitto-stretch.list

I’m not sure what this means/how to do it - any suggestions?

I fear my attempts at copying solutions from the internet are making things worse - I now have more errors when I attempt to install:

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

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libwebsockets3 : Depends: libssl1.0.0 (>= 1.0.0) but it is not going to be installed
 mosquitto : Depends: libssl1.0.0 (>= 1.0.1) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

That just means that to get the correct file for stretch (the latest debian release) you need to do

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

Since you already have something with that name, I think you have it.

Before you go any further, I would suggest using hassio to install HA. It was designed for people who struggle with the command line, and I know there is a mosquitto addon that makes installation straightforward.

If you can’t use hassio for some reason (and there are good reasons not to), here is how I suggest you proceed.

It has just occurred to me to check that you are on the latest OS release (and for that matter on a Raspberry Pi). How and when did you install your software?

1 Remove the existing mosquitto
I am not sure if it has already been forced to install, but do this anyway so you are starting from something clean

$ sudo apt-get remove mosquitto

2 Remove the extra files from /etc/apt/sources.list.d/
The wget command only needs to be run once, to get the one file that contains the location of where to get mosquitto for the stretch release. Since there are more than one, I expect that you have run the command more than once, which creates unnecessary files.

sudo rm /etc/apt/sources.list.d/mosquitto-stretch.list.1 /etc/apt/sources.list.d/mosquitto-stretch.list.2  /etc/apt/sources.list.d/mosquitto-jessie.list.1 pwfile

Now you should have one file in /etc/apt/sources.list.d called mosquitto-stretch.list, and nothing else from mosquitto

$ ls /etc/apt/sources.list.d/
mosquitto-stretch.list  raspi.list

This file should have this in it

$ cat  /etc/apt/sources.list.d/mosquitto-stretch.list 
deb http://repo.mosquitto.org/debian stretch main

Once you get to this point we can go on.

Good Luck :grinning:

Thanks for being so patient and helpful!

Yes I am running a raspberry pi (1 b). Months ago I had tried a hass.io install but the old pi doesnt have enough ram to install any add on components (SMB, etc). A few other people reported the same problem in a thread I made.

I then used Hassbian to install home assistant (which was relatively simple!)

Your instructions to clean up my mess were great. I’ve now removed all the rogue files, and I’m up to the point where I only have the files you mention.

ls /etc/apt/sources.list.d/ returns:
mosquitto-stretch.list raspi.list

and cat /etc/apt/sources.list.d/mosquitto-stretch.list returns:
deb http://repo.mosquitto.org/debian stretch main

I use a Pi 1 B+, so I guess I would have the same problem with hassio.

But I am concerned about which version of the OS you have, if you installed a few months ago. Hassbian changed to using stretch fairly recently, so unless you upgraded the os yourself, you are likely to still have the jessie version, in which case you are likely to see the sort of problems you are.

I’m can’t think of a command to check which version you are using, but if type python3 on the command line, which version of python does it report?
jessie had version 3.4 whereas stretch has version 3.5

If you are still on jessie it may be worth upgrading before going further, as python 3.4 not be enough to run HA something in the new year.

Edit: And I have just thought, I understood hassbian has a script to install mosquitto. Have you tried that?

9

Try using the mosquitto install script from here:

The command below:

sudo hassbian-config install mosquitto
1 Like
10

Depending on what version you are using, you may need to remove the /etc/apt/sources.list.d/mosquitto-stretch.list file in order to get the hassbian script to work, as that file may tell apt to fetch mosquitto from the wrong place.

11

Thanks Graham - I’m running the stretch version

pi@hassbian:~ $ uname -a

when I was originally trying to install mosquitto I tried the script - but it failed due to the error about dependencies.

I will give it another go now that you have helped me fix all the other errors I managed to introduce!

12

I re-tried the hasbian mosquitto install script without any luck.

I seem to be getting an error that it is ignoring ‘mosquitto-stretch.list.1’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extension; a pubic key is now available and it can’t install libwebsockets3 dependency.

I copied the full output below.

This is because the installer did another wget to fetch the file from the mosquitto repository. It obviously isn’t intellgent enough to recognize that the file was already there.

Provided that mosquitto-stretch.list.1 and mosquitto-stretch.list files are the same, it won’t make any difference, as it will use the correct one.

This is slightly more confusing. It seems to be referring to a jessie repository. I don’t have any references to a jessie backport in my /etc/apt directory, so I have no idea where it is coming from.

Again, this is something that indicates there is something wrong the apt configuration. I haven’t seen this before, so I have no idea about it.

This is the actual problem. For some reason libssl1.0.0 isn’t being installed automatically.

Try

sudo apt-get install libssl1.0.0

To install this library manually. Its installed on my Pi, but there may be a conflict or something on your system that is preventing it.

And then run the update again. (You could rm /etc/apt/sources.list.d/mosquitto-stretch.list /etc/apt/sources.list.d/mosquitto-stretch.list.1 first, just to get rid of those errors)

14

so this is what I get when i try to install libssl1.0.0

I am concerned that this repository is being used. I am not sure how it got in to your apt set up for stretch. It may work, and the relevant files seem to have been installed, so its worth while trying for now. But future upgrades may be a problem.

The errors are regarding mariadb, which you seem to have tried to install in the past, and it still seems to have errors.

So it is worth trying to install mosquitto using the hassbian scripts again, just remove the mosquitto-stretch.list files from /etc/apt/sources.list.d/ to avoid warnings about that again.

16

just follow the steps
