vide aussi de mon côté
Par contre :
$ dpkg --list | grep dhc
ii dhcpcd5 1:8.1.2-1+rpt5 armhf DHCPv4, IPv6RA and DHCPv6 client with IPv4LL support
ii isc-dhcp-client 4.4.1-2.3 armhf DHCP client for automatically obtaining an IP address
ii isc-dhcp-common 4.4.1-2.3 armhf common manpages relevant to all of the isc-dhcp packages
Mouarf j’ai réussi à faire 2 fois de suite une typo … En fait c’est dhcpcd (pour “DHCP client daemon”) T_T … Je me demande combien de point ça vaut au scrabble …
Du coup : dpkg --list | grep dhcpcd
Edit: oui voila on est censé voir dhcpcd5 en version 8.1.2-1+rpt2 (ou plus)
admin@lmc:~ $ sudo dpkg --list | grep dhcpcd
ii dhcpcd5 1:8.1.2-1+rpt5 armhf DHCPv4, IPv6RA and DHCPv6 client with IPv4LL support
~$ sudo dpkg --list | grep dhcpcd
ii dhcpcd5 1:8.1.2-1+rpt5 armhf DHCPv4, IPv6RA and DHCPv6 client with IPv4LL support
Cool
Du coup @aoz est-ce que ça résoud le pb d’éditer le fichier ?
@beelu : est-ce que systemctl | grep dhc retourne quelque chose ?
Editer quel fichier comment ?
Moi, j’ai résolu le problème via les commandes que je liste dans mon 2ème message dans ce fil.
je n’avais pas vu ton message
j’ai un entretien maintenant, je teste un reboot dans ~30 minutes ou en début de soirée

admin@lmc:~ $ sudo systemctl | grep dhc
dhcpcd.service loaded active running DHCP Client Daemon
admin@lmc:~ $
dhcpcd.service.d n’existe pas
du coup répertoire créé puis creation du wait.conf avec:
[Service]
ExecStart=
ExecStart=/usr/lib/dhcpcd5/dhcpcd -w
j’ai remis le fichier /etc/network/interfaces à son état intitial
NB: ça c’est la ligne qui apriori marche pas … Il faut mettre
ExecStart=/usr/sbin/dhcpcd -w
re-reboot après correction dans wait.conf. J’accède bien au serveur.
a la vue de toutes les bricoles effectuées depuis ce matin, je tenterais bien de partir d’une 4.4, d’effectuer à nouveau la migration puis la modif que tu me suggères qui semble fonctionner 
ça va me prendre un paquet d’heure, mais ça permettrait de valider la solution

Quand je reboot le problème est à nouveau là.
J’ai appliqué ta suggestion :
nano /etc/systemd/system/dhcpcd.service.d/wait.conf et à remplacer la dernière ligne par : ExecStart=/usr/sbin/dhcpcd -w
J’ai rebooté → le problème est toujours là
Hmmokay dans ce cas regardons sudo journalctl -u dhcpcd -n 100 --no-hostname --no-pager

Hmoké donc déjà tu peux confirmer que ton RPi se connecte à Internet en wifi ?
Tu es sur que après avoir reboot il n’y avait pas d’internet …? Genre dans le log on voit à 18h31 (apriori c’est le moment où tu as reboot) qu’il a bien obtenu "192.168.0.86 for 43200 seconds " … ?
