    product: Latitude 7490 (081C)
    vendor: Dell Inc.
    *-cpu
    description: CPU
          product: Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz

    product: Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Thermal Subsyste
    vendor: Intel Corporation

I have the following errors stopping the Ubuntu to update

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.
Transaction failed: Package dependencies cannot be resolved
 The following packages have unmet dependencies:

libgl1:i386: Depends: libc6 (>= 2.4) but 2.27-3ubuntu1 is to be installed
             Depends: libglvnd0 (= 1.0.0-2ubuntu2.3) but 1.0.0-2ubuntu2.3 is to be installed
             Depends: libglx0 (= 1.0.0-2ubuntu2.3) but 1.0.0-2ubuntu2.3 is to be installed

I tried to do 

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

But getting following errors

Reading package lists... Done

Reading state information... Done
Calculating upgrade... Error!
