It's attempting to execute the output of your apt-get/yum commands, lose the $(..)

You also have an issue at the start:

if [[ -n "$(grep -i fedora /etc/issue)" ]]; then

is the correct way to check if a string exists.

Your code should then look like this:

if [[ -n "$(grep -i fedora /etc/issue)" ]]; then
    echo "the OS is Fedora"
    sudo yum update -y && sudo yum upgrade -y
else
    echo "the OS is Ubuntu"
    sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y
fi
