No internet connection/ wrong Interfaces

Hi there

So i just upgraded my proxmox from version 7 to 8. After the update my Proxmox didnt come online again. After reading some Threads i saw that qith the kernel update the Interfaces change nam. I tried to rename them in /etc/network/interfaces and then restart the aervice. No luck.
After that i also saw that my interfaces are down. I also tried to bring them back up.

Here are the Photos for some information:


Thanks in advance
