[Bug 1886071] Re: Failed to calculate the system update Ubuntu 18.04.4 to 20.04

[Brian Murray]

After further investigation I've discovered this is actually due to the
wine packages you have installed with version 5.0.1~bionic. If you
remove those you should be able to upgrade to the next release of
Ubuntu.
