6 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
And it usually doesn’t affect your environment especially GPU support. But if you’d like to upgrade the kernel and you do dist-upgrade
> sudo apt-get dist-upgrade

and your kernel got upgraded then after reboot you might lose GPU support
> nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
So you need to reinstall your GPU drivers.
Reinstall GPU drivers
So just complete GPU driver install steps that are described in details in other tutorials
- Installing TensorFlow 2 with GPU and Docker support on Ubuntu 20.04 LTS
- Installing PyTorch 1.5 with GPU and Docker support on Ubuntu 20.04 LTS
Check GPU support
