OK it was not the cable.  Nor was it my router.

I needed to set the guest network to bridged. Which I think I did.

Remember I told you I was paranoid? Well the new VM has a static IP and that IP needed to be put into my Access Control List (ACL). Yikes I chased that one for lots of hours. Glad I finally figured that one out.

Hi,

You may recall I has an issue with Proxmox and trying to configure a guest Ubuntu LAMP server. For some reason during the end of the install Ubuntu would throw an error saying it could not reach the repositories. I spent several days on that issue trying every solution on the net. After 2 days I had to move on to other things.

Fast forward and I am in the process of configuring VirtualBox on an old Win10 laptop. Yesterday I got to the point of configuring an Ubuntu LAMP server.

I was thinking I would not be able to install the guest while the laptop was using WIFI. I later learned that was false. So I took the cat5 that was plugged into the failed Proxmox box and plug it into my laptop and converted to cable from WIFI.

I downloaded Ubuntu 24.04 and started the instillation process on VirtualBox. I got the same error that I got from the Proxmox box. To troubleshoot I configured the laptop to use WIFI. I then had a very slow but successful install.

Interestingly I used this same cable plugged into the same router port for another laptop that I setup as LAMP+BIND+Postfix+Dovecot web server, with no known issues.

The web server is on my right and the ProxMox box is on the left of me.

I added the RJ45 cubes to the raw cable creating this cable. I did this about 22 years ago.

Interesting find.  Not sure it is the cable or the router.

This morning I am going to visit Walmart to obtain a new cable. Walmart has rolls of cat5 of differing lengths with the RJ45 cubes already installed. I think it is worth a try.

I would have never suspected my router or my cable.

All comments are very welcome!!

Keith
