Adding new Linux Bridge or editing anything network related crashes proxmox node

[Appollonius]

So I currently have this weird issue where, I edit, add or remove anything from Linux bridges, IP addresses, anything network related makes my ProxMox node crash after I click on the 'Apply Configuration' botton on the PVE interface. It is weird as ifupdown2 is installed and it worked before but since a few days it does not and nothing changed...

After I click on the 'Apply Configuration' button I lose connectivity to my node, firewall which shuts down my VPN, so I have to restart the whole PVE node to make use of it again.

Though when I check the vms in iDrac it says that all VM's are still up and running but there is no internet connection to the outside world. So I am wondering what is going on here, as it is an network related issue...

works here. could you include 'pveversion -v' output, as well as logs from the reload task and general journal output from around the reload?

 

[Appollonius]

Yeah sure,

pveversion -v output:

Well for some reason I cannot copy the logs so I write down the error here:

Can't call the method "push_write" on an undefined value at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 255.

I have no journalctl log files.
Though I updated 2 packages last week and I believe since then I got these weird issues with applying the network configuration.

ifupdown2 version seem to be wrong. (it's the 1.2.5 version from debian repository), proxmox repo use 2.X version

are you sure to have enable no subscription repository if you don't have any proxmox license ?

Holy cow, I edited the repository settings and got 48 upgradable packages :O Well apparently the default ProxMox install does not come with these repositories...

Yes, the default installation points to the enterprise repo. Purchase a subscription key and you are done with a few clicks.

If you want to save this money, make sure you know what you are doing if you run without a subscription - and start reading the documentation, always a good idea before posting here in the forum.

Well I did read the docs, otherwise I wouldnt be able to disable the enterprise repository error but oversaw this one, as I assumed ProxMox already installed all the right repositories except the Enterprise one.
