Ubuntu 20.04.2 LTS display “34 updates can be installed immediately.”

Try Below Commands to update packages

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

A reboot may or may not be necessary (sudo shutdown -r 0)

For my machine i use only below command

sudo apt-get upgrade

Note : if you are root user then run command without sudo.
