After mistake in /etc/network/interfaces file configuration, and reboot all 4 interfaces on my server went to...
So, I decided to change my server's network configuration, by editing /etc/network/interfaces file.
I had IPv6 address, and I was changing it to IPv4 address.
Before changes it looked like that:
eno1 auto
iface eno1 inet6 static
address fc00::111:111:111:111
netmask 112
eno2 auto
iface eno2 inet6 static
address fc00::222:222:222:222
netmask 112
While editing the file, I mistakenly put new interface configuration like this:
eno1 auto
iface eno1 inet4 static
address 192.168.0.2
netmask 24
I saved a configuration, and continue my work.
Later, there was a strong need in the reboot, so I rebooted my server and eventually I lost connection to it (I was using SSH). Interface eno1 was not pingable.
So I went directly to the server (another part of the building), connect a monitor to it, and "ifconfig" (or ip a) showed me that all 4 interfaces were in DOWN state.
My question is - is it OK?
Should iface just skip mistakes in interfaces configuration, and not put other interfaces to DOWN state? As for me, only eno1 interface should be in DOWN state, and other should work, as long as their configuration did not changed.
I'm using Ubuntu 18.04 with all updates installed.
EDITED:
cat /etc/netplan/*.yaml does not return anything as long as directory is empty. It was run on server.
EDITED2:
So I eventually facing the same issue on VM, that I setup for test.
cat /etc/netplan/*.yaml returns:
network:
version:2
renderer:NetworkManager
networking 18.04 network-manager

Right now I'm installing VM with Ubuntu, to check if I can reproduce the issue and collect logs.

Not sure how it could be a bug if you made a mistake in the configuration.

It is definitely not expected, that you will lose all of your network interfaces, even if only one has a mistake in configuration.
