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
