Monit package causes installation to fail on Raspberry Pi

[PREngineer]

The Monit package is causing the installation to fail.

While I don't think it will help since I've never been able to reproduce this error (actually problem with monit package not install script or OMV), I changed to the install script to install monit before OMV. I just tried the change on a fresh 05-27 raspberry pi os lite image and it worked fine. https://github.com/OpenMediaVault-Plugin-Developers/installScript/commit/d3e59cd9b09a2bd447e3d5967597ea7be69ac1c3

You will have to write a fresh image for it to really make any difference.

@PREngineer Although I didn't do this on a Raspberry Pi, I managed to find a solution, I hope this works for you as well if @ryecoaaron 's solution didn't (I've quoted the page for your convenience):

On Debian Buster, Monit is available on backports repository. Add buster-backports: printf "%s\n" "deb http://ftp.de.debian.org/debian buster-backports main" | \ sudo tee /etc/apt/sources.list.d/buster-backports.list Install monit: sudo apt update sudo apt install -t buster-backports monit

Same to me. Fiddling around with the failing monit issue since weeks. Tried a new SD card, older Buster version, older monit version (https://forum.openmediavault.org/index.php?thread/30788-monit-error-on-fresh-install-of-omv5-on-a-raspberry-pi/) Already tried what @udop1 mentioned. Thanks for that btw.

pi@raspberrypi:~ $ sudo dpkg --configure -a Setting up monit (1:5.26.0-1~bpo10+1) ... [....] Starting daemon monitor: monitSegmentation fault failed! invoke-rc.d: initscript monit, action "start" failed. dpkg: error processing package monit (--configure): installed monit package post-installation script subprocess returned error exit status 1 Errors were encountered while processing: monit

I can't believe, that this issue is only happening to two people?! Any help would be highly appreciated. Thanks and greetings from germany

[ryecoaaron]

I just tested this on an RPi on Friday. Are you writing the image and running the script first thing? That is what I did.

[ryecoaaron]

What I dislike is that I am trying to fix the install script for a problem with the monit package and a problem I can't reproduce. Not a good use of my time.

[cptTesa]

Dear @ryecoaaron I'm really sorry that I can't provide any further details on that. But this is more or less exactly what I did, or what I did the last time: Download Raspberry OS, at the moment the latest release from 2020/05. Do an apt update, followed by apt upgrade. Then fire up the install script. It always fails with the message in the initial post. Thanks a lot. Edit: also tried it without the update/ upgrade stuff. Same result

[ryecoaaron]

Can you try one more workflow?

write image boot system change hostname (ie hostnamectl set-hostname rpi4b) reboot run install script

[cptTesa]

Clean SD card, burned the image, ssh on the pi, changed the hostname, reboot, started the install script, that's it:

[PREngineer]

I read here that the latest version of monit in Raspbian is broken for certain devices and that I should try to install a previous version. But it didn't fix it for me either.

I'm about to give up on OMV for my Raspberry PI.

[ryecoaaron]

On a failed system, can someone please post the output of: apt-cache policy monit?

monit is supplied by OMV and raspbian. My system from Friday has the raspbian version which is older than the OMV version.

[ryecoaaron]

Thanks for the output. You didn’t need the question mark on the end of the command. That was just part of my sentence:) But it does tell me you have to omv package installed. Maybe the omv package has issues on raspbian. I have something to try now.

[cptTesa]

Great news. I was quite sure that it was part of your sentence. Fiddled its way into the console. Copy/Paste issue ;-) Anyways. Thanks for digging in. Good night.

[ryecoaaron]

No matter what version I install on fresh images, I can't get it to fail. I even tried upgrading and downgrading multiple times. Can someone try:

write fresh image boot system sudo apt-get update sudo apt-get install monit

If it fails, can you post the output of: sudo systemctl status monit sudo journalctl -u monit

[cptTesa]

Done what you said:

[cptTesa]

I think the phone messed it up. Will edit later

[ryecoaaron]

@cptTesa did the monit upgrade fail?

[cptTesa]

Think so. As "the script mentioned" one package is upgradable and upgraded monit.

The upgrade itself went fine. Afterwards same behavior as above:

.... Errors were encountered while processing: monit E: Sub-process /usr/bin/dpkg returned an error code (1) failed installing monit

[ryecoaaron]

I made another change to the script where it installs monit from the raspberrypi repos (on RPis) and won't upgrade monit to the OMV version.

[cptTesa]

Alright @ryecoaaron Things went fine. Somehow. Installation done. Saw some red entries around the php-stuff. Now there is a 502 Bad gateway reported by nginx on the main page. But so far: thanks a lot.
