Installer fails to "upgrade" a partial Tails installation
On “clone & upgrade”, if the target Tails partition has some files
remaining from a broken, or partially removed (e.g. after another failed
upgrade) Tails installation, then self.live.existing_live_os is false,
and then the installer does not deletes the existing files before
copying the new ones, and then it fails in similar ways to what is fixed
by liveusb-creator’s
bugfix/dont-fail-upgrade-if-tmp-dir-exists-on-destination branch.
In “clone & upgrade” mode, all files that are expected to exist in a
Tails system partition should be deleted whenever they exist, regardless
of what self.live.existing_live_os thinks is in there.
