Part 2 :Failure to access repositories when installing Ubuntu 23.10 and 22.04 on Proxmox

[techlists at phpcoderusa.com]

Todd, thank you so much for your help!!


I went to datacenter->Firewall->Options and Firewall was already set to 
No.  I assume this is at the Proxmox level.  Problem still persists.

Then I went to Datacenter->PVE->Firewall->Options and the firewall was 
set to Yes.  I changed it to No and the problem persists....

Then I went to each VM->Firewall->Options and each VM had the firewall 
set to No.  Problem still persists.

I rebooted Proxmox and the problem still persists.

I am perplexed as to why the two VMs I installed prior to upgrading 
Proxmox from 7 to 8 can access their repos (sudo apt update) and any new 
installs cannot access their repos.

Any thoughts are much appreciated.

Keith
