While doing a do-release upgrade from 18.04 to 20.04, I got an error. The script wanted to install the Chromium snap and apparently while doing that, it failed.
Original summary generated by Launchpad:
package chromium-browser 87.0.4280.66-0ubuntu0.18.04.1 failed to install/upgrade: new chromium-browser package pre-installation script subprocess returned error exit status 1
