do-release-upgrade crashed with OSError in authenticate(): [Errno 5] Input/output error

[Brian Murray]

I was looking at a crash report in the Ubuntu Error Tracker, https://errors.ubuntu.com/problem/cdab89fcafebeb89cb00fd1334bafc73549a2517, and trying to figure out how it could have happened and was able to recreate it with the following steps.

1) Open a terminal
2) Run do-release-upgrade --frontend DistUpgradeViewGtk3 -d
3) Authenticate
4) Observe the Release Notes dialog
5) close the terminal
6) Click Upgrade
