I've just install latest proxmox (9.0.-1), set repository to "no-subscription'
After I've applied all update and reboot - lost network connection to proxmox.
Enter console - there was no bridge online, but config OK.
Running ifup vmbr0 - error "Persmission denied"
Checked how is ifupdown2 running - find, that __main__.py and __init__.py in /usr/share/ifupdown2 didn't have execution bit. Set execution bit, run ifup OK. Restart for check - network available.
