This is a common problem after MySQL upgrade.
The issue is, the symlink /usr/share/mysql-common/configure-symlinks doesn't exist.
Just create the symlink and run apt upgrade or apt-get upgrade and it will work
We can do the following to fix the issue
touch $$ : this creates a file with a unique name.
touch /tmp/$$.$$ ; cd /usr/share/mysql-common/ ; ln -s /tmp/$$.$$ /usr/share/mysql-common/configure-symlinks ; chmod 777 /usr/share/mysql-common/configure-symlinks ; apt -y upgrade ; rm -f /tmp/$$.$$
note - the issue has appeared in older versions as well and the usual fix is to remove and install mysql. but the method here is better
