[Bug 1747619] Re: package samba-common 2:4.3.11+dfsg-0ubuntu0.16.04.12 failed to install/upgrade: subprocess installed post-installation script returned error exit status 10

Les paquets qui suivent ne possèdent pas de fichier de contrôle de liste dans la base de données et doivent être réinstallés :

and

Les paquets qui suivent ne possèdent pas de fichier de somme de contrôle MD5 dans
la base de données et doivent être réinstallés
=The following packages do not have an MD5 checksum file in the database and need to be reinstalled

for about ~2800 packages

Sound really bad.
Almost as if all of the DB would be gone?

This installation seems severely broken.
I'd not immediately recommend to install all of them.
Lets start slowly - reinstall "one" and see if they are removed from the list.
Lets pick one you surely have and don't want to uninstall like "bash".
If you do:
$ sudo apt install --reinstall bash
Does after that bash remove from the output of dpkg --audit ?


Furthermore there is a debconf warning (unrelated), but I found this bug 1669270 and quote from there:
"An error code of '10' from debconf generically means that wrong arguments have been passed.
Please show the output of 'debconf-show ucf'"

It might be needed to regenerate the ucf and the package database, but I'm not sure how :-/
But we should at least check for uvf and apt status to then go crazy about it if it looks as bad as dpkg --verify:
$ sudo debconf-show ucf
$ sudo apt-get check
