On our vagrant dev environment, when provisioning (Vagrant box debian 9.13) I install Supervisor using shell provisioner. Always working as expected. That's the content of the script:
#!/usr/bin/env bash
sudo DEBIAN_FRONTEND=noninteractive apt-get -y install supervisor=3.*
cp /home/vagrant/projectX/vagrant/configs/supervisor/supervisord.conf /etc/supervisor
chmod 777 -R /etc/supervisor/conf.d
A few days ago, it turns out that Supervisor is not being installed anymore when provisioning.
The error we get is:
Reading package lists... Done Building dependency tree Reading state information... Done Selected version '3.3.5-1' (Debian:10.10/oldstable [all]) for 'supervisor' 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: supervisor : Depends: python-meld3 but it is not installable E: Unable to correct problems, you have held broken packages.
Also, trying to install manually using: (Supervisor 4.* is not using python-meld3, that's why tried)
sudo apt-get update
sudo apt-get install supervisor -y
I got:

This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'supervisor' has no installation candidate
Things I have tried:
Installing python-meld3:
sudo apt-get install python-meld3 -y

Also by downloading the code from meld3 Github and installing by hand with same result.
Fix dependencies

Then added to /etc/apt/sources.list and sudo apt-get update and all of them are ignored...

What is happening? What I'm missing? It's being quite difficult to install it. Any help would be really appreciated!
PD: I cannot upgrade to Debian 10 or 11. We are fixed to 9.13
apt-cache policyshows you have Debian 10 (buster) APT sources somewhere.busterin your "apt-cache policy" output. Debian Buster is Debian 10. If the main sources.list file doesn't reference it, then something in thesources.list.d/directory probably does.
