Network is unreachable

This command ip link show type "" did not give any output

My bad, without link it does not show anything.

I am not 100% sure but I think HP2 server is using proxmox 8.2

you can run "pveversion" to get a precise version tag. But regarding the real issue, I am unfortunally out of ideas.

How about for a start to manually create the bridge and assign IP to it?
If any error occurs, please post it here.

brctl addbr vmbr0
brctl addif vmbr0 eno1
ip a add 10.0.0.30/24 dev vmbr0
ip r add default via 10.0.0.1 dev vmbr0

It looks like the bridge-utils aren't loaded or Installed.

The bridge-utils are installed ; 1.7.1-1 amd64

the last line
ip r add default via 10.0.0.1 dev vmbr0
gave an error --> Error: Nexthop has invalid gateway.

Hi @marcelw60,
I would reinstall PVE at this point, if you don't have any Important VMs or have Backups.
It still looks like a network config issue.

Another Question I have,
did you manually change the network config in the file, before this issue appeared?

If so:
Delete all vmbr0 entries and set the IP direct on the Port:

auto eno1
iface eno1 inet static
        address 10.0.0.30/24
        gateway 10.0.0.1

The large spaces are Tab stops

the last line
ip r add default via 10.0.0.1 dev vmbr0
gave an error --> Error: Nexthop has invalid gateway.

This error only appears, if device's IP and the gateway are not in the same network. Should not happen in this scenario.
Could you provide the output of brctl show vmbr0 and ip a s vmbr0 ?

 

[marcelw60]

Could you provide the output of brctl show vmbr0

sure!

output brctl show vmbr0

Another Question I have,

Yes I changed manually in the process above the network config

config file:

auto lo
iface lo inet loopback

iface eno1 inet manual
auto vmbr0
iface vmbr0 inet static
             address 10.0.0.30/24
             gateway 10.0.0.1
             bridge-ports eno1
             bridge-stp off
             bridge-fd 0

 

[fba]

output ip a s vmbr0
3: vmbr0: <BROADCAST, MULTICAST› mtu 1500 qdisc noop state DOWN group default glen 1000

Try an ip link set up vmbr0 to enable the bridge. And if it works ip r add default via 10.0.0.1 dev vmbr0

iface eno1 inet manual
auto vmbr0

             address 10.0.0.30/24
             gateway 10.0.0.1
             bridge-ports eno1
             bridge-stp off
             bridge-fd 0

Is it a typo or is there no space between eno1 and vmbr0?

It should look like this:

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
             address 10.0.0.30/24
             gateway 10.0.0.1
             bridge-ports eno1
             bridge-stp off
             bridge-fd 0

Wow, great!
This worked!
I could ping 1.1.1.1, so network is available

What's the next step I should/could do to make all this permanent and survive a reboot?

 

[fba]

First of all, run ifreload -a -s
This does a syntax check on the interfaces file. The command should return without any visible output, if there are no errors.

 

[marcelw60]

hmm, I rcvd this reply, despite being the root user.

root@pve-hp2:~# ifreload -a -s
-bash: /usr/sbin/ifreload: Permission denied

Please try, what is described here at the end: https://forum.proxmox.com/threads/updated-packages-restarted-no-internet.136230/post-603817

 

[marcelw60]

I did use the below command; received the following error

root@pve-hp2:~# dpkg --configure -a after apt upgrade
dpkg: error: --configure --pending does not take any non-option arguments

Type dpkg --help for help about installing and deinstalling packages [*];

[fba]

The command is dpkg --configure -a

 

[marcelw60]

My wrong

I saw a lot of error messaging;
The last lines

It looks like there is too less HD space;



I tried to delete a non active LXC ;
I got this error

Well spotted, just free some space and try again.
