Mosquitto and emonhub not starting anymore after update

I did a full update and nothing worked anymore
Then I did a apt-get update and upgrade and most of the services started to work
except mosquitto (1.5.7-1+deb10u1) and emonhub
I think emonhub won’t work because of mosquitto ( I use it in emonhub)

The problem is I don’t see anything wrong in the logs

-- The unit mosquitto.service has entered the 'failed' state with result 'exit-code'.
Aug 13 21:20:02 emonpi systemd[1]: Failed to start Mosquitto MQTT v3.1/v3.1.1 Broker.
-- Subject: A start job for unit mosquitto.service has failed
-- Defined-By: systemd
-- Support: https://www.debian.org/support
--
-- A start job for unit mosquitto.service has finished with a failure.

what should I check?
should I downgrade mosquitto?

[edit]
You will need to tell us your HW and OS as a starting point. If a Pi,

Is this an emonPi or an emonBase? What base image?

I still need this answer

Is this an emonPi or an emonBase?

what does

systemctl status {mosquitto.service,emonhub.service}

say?

When posting code or bash output, please put in 3 ‘backticks’ (found at the top left of the keyboard normally) on a line on their own, then the code, then 3 more backticks on a line following the code.

    ```
    code
    ```

If it is something like php you can add a language identifier that after the first 3 backticks so ```php

Did you do a dist-upgrade?

No, I did not

the problem seems to be caused by the symbol lookup error

the lib is part of gcc, I think
I already tried apt-get reinstall gcc-arm-linux-gnueabihf
it did not seem to fix the problem though

I have just checked my emonPi, and I am on OS: Linux 4.19.118-v7+ which is quite different.

Try reinstalling the mosquitto package.

apt-get reinstall mosquitto did not work
however I removed mosquitto, then apt autoremove and I reinstalled mosquitto and not it works.

however, emonhub still does NOT work
