Hi,

I did an update of my server and after the reboot, cannot access the web gui.
I tried to restart the pveproxy service and the log shows “permission denied” and i did a chmod 777 /var/log/pveproxy/access.log command…
Also i tried to do apt install proxmox-ve

Nothing works...

Some ideas? I'm desperate

Thanks

Hi,

I tried to restart the pveproxy service and the log shows “permission denied”
What user did you run the command as? Could you post the output of:
  • pveversion -v
  • systemctl status pveproxy
  • systemctl status pvedaemon
Can the server still be accessed via SSH?

did a chmod 777 /var/log/pveproxy/access.log command
I would change this back to '640', as it shouldn't have anything to do with the issue.

Best regards,
Dylan

Could you also post the output of?
  • ls -ld /var/log/pveproxy
  • ls -l /var/log/pveproxy
Additionally, what version did you upgrade from?

That access.log.1 was created by me and access.log doesnt contain anything.
Additionally, what version did you upgrade from?
I update some packages, i dont know which ones. Just did an update from Web Gui and then, and dont know how, i accidentally did rm -r /var/log [facepalm] Sorry for not mentioning this on the beginning of the post.

Okay, if it was an update from the GUI, it was likely a minor update anyway.

Ah, this explains it ;)
The directory /var/log/pveproxy and its contents should be owned by 'www-data'. Can you run the following command to see if it fixes the issue?
chown -R www-data:www-data /var/log/pveproxy
