[SOLVED] Lost all networking, unsure of how to fix.

[MrMe01]

Short of reinstalling PVE, I have no idea how to fix networking.
I had an update for tcpdump, I created an Ubuntu Server VM for Nextcloud, and used the poweroff command over SSH to turn the machine off when I was done with it for the day. It's a work in progress at the moment.

Since then I have lost networking, I have lxde installed on it (first thing I installed, post install), wicd likes to think that it's connected and has an IP, I changed the IP in PVE manager, rebooted and that made no difference (thinking it would refresh something or propagate changes where necessary, to no avail)

I would naturally reinstall at the moment, however this is not Windows, I have VM's that I cannot move due to no networking and I am under the impression that this is fixable. I just need guidance.

/etc/network/interfaces, for those who wish to see it is attached.

adding "auto eno1" before "iface eno1 inet manual" should solve your problem
Take a look to attachment.

After this modify /etc/hosts to adjust it if ip is changed

I'm getting the following on statrtup from systemcl,

• UNIT| LOAD | SUB | JOB DESCRIPTION
• networking.service | loaded failed | failed | Raise network interfaces
• nmbd.service | loaded failed | failed | Samba NMB Daemon
• pvecluster.service | loaded failed | failed | The Proxmox VE cluster filesystem
  
• pveproxy.service | loaded failed | failed |PVE API Proxy Server
• snap.nextcloud.apache.service| loaded failed | failed |Service for snap application nextcloud.apache
• spiceproxy.service | loaded failed| failed | PVE SPICE Proxy Server
  

I have tried ifup eno1, but I'll give that a shot now.

attach file
/etc/udev/rules.d/70-persistent-net.rules
please

 

[MrMe01]

I have no such file in that directory.

EDIT: the failures listed by systemctl has changed. I'll attach them in the following post

 

[MrMe01]

The updated failed modules are
pve-cluster.service
snap.nextcloud.apache.service

 

[MrMe01]

I just ran systemctl status pveproxy.service,

I get the following in the output,

/etc/pve/local/pve-ssl.key: failed to load local private key (key_file or key) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1626.

 

[MrMe01]

I think I have fixed it, running service pve-cluster restart seems to have recreated the file pve-ssl.key
Rebooting now, fingers crossed

//EDIT: Still broken with the errors listed, I do now have networking, internet and SSH access. I'll keep at it, I'm sure I can fix it now

 

[MrMe01]

Just dug through the services, it seems this comes back to corosync.service. Any ideas on that?

 

[MrMe01]

Fixed, needed to edit /etc/hosts to proper formatting.
