Hi,
I think I’ve seen this before. Let’s verify.
First, update the package lists and perform any upgrades including any packages that are currently phasing.
$ sudo apt update
$ sudo apt upgrade -o apt::get::always-include-phased-updates=1
Now please post the resulting output of the following
$ apt list ~i~n^nvidia | awk -F'[ /]' '{print $1, $3}'
