[xubuntu-users] cryptic msg from ubuntu

[John R. Sowden]

I rcvd 2 updates from ubuntu in the last day or two with the below message:

SORRY, THERE ARE NO MORE UPGRADES FOR THIS SYSTEM

There will not be any further Ubuntu releases for this system's 
architecture.
Updates for Ubuntu, 18.04 will continue until 2023-04-26.
If you reinstall Ubuntu from ubuntu.com/download, future upgrades will 
be available.

Since I an running 18.04, on a 32 bit system, I am confused. Can someone 
explain?
