[SOLVED] Problems after upgrade from Proxmox 7 to 8.0.4

Hi group

Upgraded from latest Proxmox 7 to rel 8.0.4 and ran into some problems

First I ran into the problem that the ethernet interface did not come up again, and when trying to manually bring the interface up with ifup, I got the error "Permission denied" even that I was root.
It showed up the the ifup is now a link to some Python code under /usr/share/ifupdown2/ , and the files __main__.py and the file __init__.py both missed the executable flag for all groups
Given the executable flag to these 2 files fixed my Proxmox box and I got network connectivity again, but now I'm facing another problem

Trying to update my Proxmox box it crashes for every retry- Both from the GUI and from CLI

I get this strange message running apt upgrade (After the apt update)
Reading database ... 62150 files and directories currently installed.)
Preparing to unpack .../proxmox-kernel-6.2.16-12-pve_6.2.16-12_amd64.deb ...
Unpacking proxmox-kernel-6.2.16-12-pve (6.2.16-12) over (6.2.16-12) ...

And then the box crashes !!

Why do the system try to unpack on top of the already installed proxmox kernel in same release ?
And why do the system tell me that the proxmox-kernel-6.2.16-12-pve/now 6.2.16-12 package can be upgraded to 6.2.16-12 (See below)

As can be seen same kernel is already installed on the system

root@pve2:/usr/share/ifupdown2# apt list --installed | grep -i proxmox-kernel

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

proxmox-kernel-6.2.16-12-pve/now 6.2.16-12 amd64 [installed,upgradable to: 6.2.16-12]
proxmox-kernel-helper/now 7.4-1 all [installed,upgradable to: 8.0.3]

Any suggestions or help are very appreciated

Thank you for the output!

Do you have this issue on all nodes?

Can you please check the Syslog looking for any interesting errors during the upgrade process?

Can you please check if you have an update for the BIOS?

Regarding the ifreload (network issue) can you please also check of the output of `ifreload -a` this command should not result anything if everything ok.
Hi Moayad
Just got an answer on what is wrong
Tried to install Ubuntu 22.04 that also uses the 6.2 kernel and when the kernel loaded during installation the system crashed
I'm running on a NUC10i7FNH that have been running without any issues with Proxmox 7
But it seems like this NUC model has some issues with Linux kernel in rel 6.2 according to Google, so it is actually not a Proxmox problem, but the kernel that is causing the problem
Found a suggestion to disable "Intel Turbo Boost Technology" in the bios when running on Linux kernel 6.2 and that fixed the issue on both Ubuntu and on Proxmox.
