Incorrect overwiting release variable

[chromigo]

# Check system
check_sys(){
    if [[ -f /etc/redhat-release ]]; then
        release="centos"
...
    elif cat /proc/version | grep -q -E -i "centos|red hat|redhat"; then
        release="centos"
    fi
    release="ubuntu"
    #bit=`uname -m`
}

script contains overwriting logic for release release="ubuntu" in the end of secrion so all previos if logic does not apply
Consider remove this
