I recently downloaded buster image (2019-07-10) and it is working fine. However when I run sudo apt-get upgrade I'm getting and error when it is upgrading realvnc with the following message:

new realvnc-vnc-server package post-removal script subprocess returned error exit status 1

The pi seems completely frozen mouse and keyboard doesn't work, time not updating. Best way to proceed and what is causing this error? Alt+PrintScreen + R E I S U B okay to force shut down?

Before doing an upgrade you should update the package lists:

rpi ~$ sudo apt update
rpi ~$ sudo apt full-upgrade
rpi ~$ sudo systemctl rebooot

If this also does not work then you can try to reinitialize the package lists. How to do it look at https://raspberrypi.stackexchange.com/a/93630/79866.
