[Bug 1686117] Re: upgrade from Zesty to Artful fails

[Brian Murray]

This only affects the DistUpgradeViewText frontend and the source of the
problem seems to be the logfile for screen.

screenrc contains "/var/log/dist-upgrade/screenlog.%n"

and

DistUpgradeMain.py calls screen with "-L" but no log file name.  I'm
pretty sure this used to work on upgrades from Y to Z. While passing the
log file name to the -L switch works, there may be a better solution
e.g. making sure screenrc is sourced or finding out if there is a bug in
screen.

  This'll need some investigation.
