It used to update just fine. I am not sure where the problem is. I added a second repository I found in the forums this is why there is a duplicate source error. This did not fix the problem. Connection is fine I can ping 8.8.8.8 in Shell.

Thank you.

Connection is fine I can ping 8.8.8.8 in Shell.

It could still be a DNS configuration issue. Are you able to ping "proxmox.com"?
Could you post the output of: cat /etc/resolv.conf?

 

[DigiDoc]

I am unable to ping "proxmox.com". I can see the packets sent through my firewall but nothing is received. This is a universal problem across all my network.

Output to command as follows:

root@pve:~# cat /etc/resolv.conf
search local
nameserver 10.61.71.1

 

[dylanw]

Can you confirm that your DNS server (10.61.71.1) is active and functioning correctly? Is it reachable from the Proxmox VE host?
If any other systems use it, you can also check if DNS resolution functions correctly on them.

 

[DigiDoc]

I figured that my DNS server address was changed. I changed it in the GUI but I noticed that it did not reflect in resolve.conf

Case closed, Thank you much!
