Bonjour.
Merci Yull pour tes informations. Je suis dans le même cas, avec une installation de sme en français.
Je me permet de résumer mes tests.
Installation of sme10. Server : update, internet access--> Ok
Client : 
 - DHCP : not working--> signal-event e-smith-base-update-->DHCP : Ok
 - Internet : OK
 - Sme-manager : OK
 - //smeserver/primary : Ok
 - Joining the domain : Ok
I try to restore v9.2 through the admin console: no 9 restoration, maybe the signal-event e-smith-base-update remove this possibility.
For JPP, Reinstallation of sme10, restoration during installation, Server : update, internet access--> Ok
Client:
 - signal-event e-smith-base-update-->Dhcp not working
 - signal-event post-upgrade ; signal-event reboot -->Dhcp : Ok
After rebooting
 - Internet: OK
 - Sme-manager not working
 - //smeserver/primary : not working
 - Joining the domain : not working
rm /home/e-smith/ssl.*/* -f
signal-event ssl-update
systemctl restart httpd-e-smith
signal-event post-upgrade ; signal-event reboot
 - Sme-manager : Not working
 - //smeserver/primary : Not working
 - Join domain : Not working
 - ls /home/e-smith/ssl.key-->a key was create
 - ls /home/e-smith/ssl.crt-->nothing
I will try yull's method this afternoon or tomorrow.
Have a nice day.
