Raspbian Stretch install error

[Obo666]

Issue: cannot install Mosquitto under Raspbian Stretch, following instructions at https://mosquitto.org/2013/01/mosquitto-debian-repository/ with http://repo.mosquitto.org/debian/mosquitto-stretch.list

Error: pi@raspberrypi:/etc/apt/sources.list.d $ sudo apt-get install mosquitto Reading package lists... Done Building dependency tree Reading state information...

I am facing the same issue. 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 E: Unable to correct problems, you have held broken packages.

Yeah, I think quite a few people are. Appears to be a bit of a show stopper. Hopefully a response will be forthcoming.

[MikePRoberts]

Is this linked to Debian Stretch dropping SSH1- and hence a broader Linux issue? See https://www.debian.org/releases/stable/i386/release-notes/ch-information.en.html

It works..Everything is working after i used aptitude

Thank you for your quick reply.

A reply on the forum link below suggests that the problem would be solved by your updating your dependency list. Doing this would enable a load of people using the Pi for IoT and to load Mosquitto the normal way. Could you do this?

Thank you

Mike

same here. Could u fix it for Debian Stretch?

Thanks

[nmaas87]

would be awesome, thanks a lot!

[aniketdali]

I tried this to fix it 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

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 E: Unable to correct problems, you have held broken packages.

aniketdali's comment above will fix the libssl1.0.0 error... but libwebsockets3 is still not installable.

[davyike]

Hi all, following aniketdali's tip I've used the following to install on Raspberry Pi with Debian Stretch:

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-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
wget http://ftp.nz.debian.org/debian/pool/main/libw/libwebsockets/libwebsockets3_1.2.2-1_armhf.deb
sudo dpkg -i libwebsockets3_1.2.2-1_armhf.deb
sudo apt-get install mosquitto mosquitto-clients

[BITRU]

davyike thank you! worked.

[tmofoshodo]

@davyike what model raspberry pi are you using?

[davyike]

@tmofoshodo I'm using a Pi 3 Model B. Don't think that should matter as much as the Raspbian image though, I am using the latest Raspbian Stretch Lite, release date 2017-09-07.

[tmofoshodo]

@davyike Thanks for the reply. I am using a Pi Zero W. Your steps allowed me to install Mosquitto, but I get "Illegal Instruction" when I try to run it. I'm thinking it might be because Pi Zero W uses ARMv6. I am going to try on my Pi 3 tonight.

[davyike]

@tmofoshodo Ah good point. Yes you may need the armel version instead of the armhf version? I'm not very familiar with that though so do your own research. You can see all the packages here: https://packages.debian.org/jessie/libwebsockets3 Same would apply for openssl: https://packages.debian.org/stretch/openssl Looking at that I see there's a much newer version of OpenSSL than I'd referenced earlier.

If you can confirm that it's needing armel then the following packages should work (you'll want to uninstall the other ones first of course):

http://http.us.debian.org/debian/pool/main/o/openssl/openssl_1.1.0f-3_armel.deb
http://http.us.debian.org/debian/pool/main/libw/libwebsockets/libwebsockets3_1.2.2-1_armel.deb

Let me know if you have any luck with that. There's probably a tidier way to do this than installing packages directly, i.e. by installing newer Debian apt-get lists or something but I'm not sure how that would work. I think this is tidier than compiling and installing from source anyway.

[jahnroux]

@davyike I am having the same issue on my Pi Zero W. I am running stretch on my Pi 2 and on my Pi Zero W. I am able to use the work around of manually installing libssl and libwensockets3 for the Pi 2 and I can get mqtt running. However, the same process on the Pi Zero W causes me to get the error message:

pi@raspberrypizero:~ $ mosquitto
Illegal instruction

I have uninstalled, reinstalled, updated, rebooted, you name it. I can't get mqtt to run on a pi zero under stretch. I may have to reinstall with Jessie tonight.

[maddhin]

@jahnroux: did you try davyike's fix w/ the armel packages just one post above?

[jahnroux]

@maddhin yes, see below:

pi@raspberrypizero:~ $ sudo dpkg -i libwebsockets3_1.2.2-1_armel.deb
dpkg: error processing archive libwebsockets3_1.2.2-1_armel.deb (--install):
 package architecture (armel) does not match system (armhf)
Errors were encountered while processing:
 libwebsockets3_1.2.2-1_armel.deb
pi@raspberrypizero:~ $

armel is not compatible with the Pi Zero architecture. I also tried libssl-armel, openssl-armel, all the same issue.

[davyike]

@jahnroux It looks like that error message is telling you that you should be using armhf packages, in which case go back to my earlier post. I'm not 100% sure on which Pi models have which architecture, so that exercise is left to the reader :)

Edit: Re-reading your comments, so you're saying that armel doesn't install, and that armhf gives an Illegal instruction response?

[jahnroux]

@davyike that is what I am trying to explain, your earlier approach works for my Pi 2, not my Pi Zero. Both the 2 and zero are running stretch. So I am able to install the armhf libssl and libwebsocket3 packages but mosquitto will not start on my Pi Zero. On the Pi 2 I was able to install and get mosquitto running.

[davyike]

@jahnroux I see, sorry I misunderstood earlier. I don't have a Pi Zero so am not able to play around and try that. I wonder if @tmofoshodo had any luck? Perhaps it's not the OpenSSL and Websocket3 packages that have the problem, maybe it's the Mosquitto package? Just throwing some ideas out there. If there's a way for you to verify if the OpenSSL and Websocket3 libraries are working, independently from Mosquitto, that would be a good first step.

[jahnroux]

@davyike thanks, yeah I don't expect you to solve my problem, I just wanted to let it be known that I ran into the same issue as @tmofoshodo

I will hack together something tonight to test the packages interdependently before I reinstall with Jessie.

[jipp]

Hi

I ran into the same issue. it looks like that stretch has libssl 1.0.2 installed by default. libwebsockets3 is not available at all.

I'm not a developer but I see a libwebsockets8 library available on stretch

one way around would be to add the jessie sources in the /etc/apt/sources.list.d/ folder - but then I get a mixture of stretch and jessi on the system - which I would like to avoid.

I'm a little clueless now as from the libs I would suggest that libssl is a broken dependency which needsto be removed for mosquitto on Stretch. For libwebsockets I cannot judge how much effort it would be to update to a new websocket lib.

[sevos]

This worked for me:

wget http://ftp.us.debian.org/debian/pool/main/libw/libwebsockets/libwebsockets3_1.2.2-1_armhf.deb
wget http://ftp.us.debian.org/debian/pool/main/o/openssl/libssl1.0.0_1.0.2l-1~bpo8+1_armhf.deb
sudo dpkg -i libwebsockets3_1.2.2-1_armhf.deb
sudo dpkg -i libssl1.0.0_1.0.2l-1~bpo8+1_armhf.deb

# If dpkg reported any packages missing, I used apt-get to get them from stretch repo

sudo apt-get install mosquitto

I understand that this mixes stretch and jessie libs and is not kosher, but works for now. Someone may use it.

[srutib]

I am running into the same problems as @jahnroux and @tmofoshodo. I keep receiving illegal instruction whenever I try to run mosquitto. I also tried @sevos solution, but still get the same illegal instruction problem.

Has anyone been able to successfully fix this problem?

[artreaktor]

@sevos workaround fixed the issue for me pi@pi1:~ $ cat /etc/*-release PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)" NAME="Raspbian GNU/Linux" VERSION_ID="9" VERSION="9 (stretch)"

[ThomDietrich]

@ralight an official statement by the maintainers regarding this issue would be interesting. It seems like a rather important one to sort out - as the comments have shown... Is anyone looking into a solution or can you give a few details about the challenges? What are the next steps? Very much appreciated! Thanks

Edit: One month has passed without any response, despite the seriousness of the matter. This is quite disappointing.

[consolacion]

I only came upon this discussion after I managed to install it. this is what I did (after I got the unmet dependencies error):

sudo aptitude install mosquitto

That presented me with options to "solve it" the first choice i cose 'n', as it would leave the situation intact. Then I got the option to install the unmet dependencies, for which I chose 'Y'

That did it for me

[s-hemer]

But this installs just the version available in the standard Raspbian repository. Funny enough that the package there has the correct dependencies whereas the one from http://repo.mosquitto.org/debian stretch main still depends on libwebsockets3

[consolacion]

yes, correct. But in the end I cared more about having an installable 'old' version than a non installable 'new version' makes one wonder, wouldnt anybody have tried installing it on stretch before releasing it into thatrepository?

[Dan-in-CA]

It is really not that hard to build mosquitto from source on raspbian stretch. See this post: https://xperimentia.com/2015/08/20/installing-mosquitto-mqtt-broker-on-raspberry-pi-with-websockets/

If you are building on a Raspi with a quad core processor it does not take long either.

[consolacion]

Thanks, I will check that out. When i did my 'solution' I only discovered afterwards that it installed a previous mosquitto distribution, but I didnt really mind. Nevertheless, I´ll give the link a try

[rogertheriault]

@Dan-in-CA thanks - your step by step instructions worked for me (Pi 3, stretch). Reminds me of the days when "make" was really the only option on unix/linux.

[Dan-in-CA]

@rogertheriault, Thanks for the feedback. Looks like the post is getting a lot of traffic but this is the first report of results.

[rogertheriault]

@Dan-in-CA that's possibly originating here, that's where I started. Though, compared to his video, my Pi wasn't dusty, it was a newly minted Stretch... (tho I do have some dusty units) http://bitluni.net/simple-mqtt-broker-setup-on-a-raspberry-pi/

[borch84]

@Dan-in-CA I confirm I was able to install mosquitto using the instructions provided for raspbian stretch

[jahnroux]

Has anyone tried the solution in Raspberry Pi Zero W?
