Issue Try update Ubuntu 14 to 16 and reboot --> no more ssh / ufw don't work / no ping

[AxelKirk]

Hi guys, I'm pretty desperate.

WHAT I HAVE DONE :


This week I try an update for my distant server from ubunut 14 to ubuntu 16 with :

/opt/psa/bin/distupgrade.helper.ubt14-ubt16.x64.sh

Then the tuto say reboot so I reboot.

php7.0-fpm start/running, process 25291

  Please reboot the server and run the following command /opt/psa/bin/distupgrade.helper.ubt14-ubt16.x64.sh to continue.
  STOP Distupgradre

WHAT I HAVE NOW:


- ping don't return

- ssh say connection Time out https://i.stack.imgur.com/NFexe.png

When I launch rescue mode and access via ssh to a linux image (I choose an ubuntu 14) on my distant server :
(By the way when I connect with rescue mode I do :

sudo su

mountall.sh
chroot /mnt/sda2 bin/bash

)


- ufw status:

iptables v1.4.21: can't initialize iptables table `filter': Table does not exist

- uname - a :

Linux 62-210-253-46 4.2.0-35-generic #40~14.04.1-Ubuntu SMP Fri Mar 18 16:37:35 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

- lsb_release -a :

No LSB modules are available.

Distributor ID: Ubuntu

- ls -lh /lib/module :

- I have often the message can't resolve hostname IP-IPI-IPI-IP , but I check hostname and host (could show you content if you want)
- In syslog I have a message :

apparmor="DENIED" operation="sendmsg" profile="/usr/sbin/named" name="/run/systemd/journal/dev-log" p

- ip address :

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
      valid_lft forever preferred_lft forever
   inet6 ::1/128 scope host
      valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
   link/ether 0c:c4:7a:0e:9f:da brd ff:ff:ff:ff:ff:ff

   link/ether 0c:c4:7a:0e:9f:db brd ff:ff:ff:ff:ff:ff

- cat /etc/network/interface so you see here it's em1 than eth0 above

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto em1
iface em1 inet dhcp

- systemclt or everything else with clt :

Failed to connect to bus: No file or folder find

And as I said, I was in an update process, so after the reboot I have to re launch the command

/opt/psa/bin/distupgrade.helper.ubt14-ubt16.x64.sh

so I'm a bit afraid of install stuff like

apt-get install lsb-core

Many many many thanks for your help !
