New changelog entries:

conffile prompt with "n" use bytes not a string. (LP: #1796193)

python3-distupgrade as it is now required by DistUpgradeController.
(LP: #1824866)

available at archive.ubuntu.com and if we do update then demotions becomes
an empty file which is wrong.
New changelog entries:
* DistUpgradeController.py: Instead of checking every sources.list entry to
see if they are accessible keep track of the uris and only test once per
uri thereby preventing situations where entries for the same server are
enabled and disabled. (LP: #1822886)

supports checking to see if an https url is downloadable. (LP: #1823410)

mount points don't use a negative number as the buffer. (LP: #1786484)

repositories, additionally pass along the environmental variable
RELEASE_UPGRADER_ALLOW_THIRD_PARTY via pkexec and sudo. (LP: #1807032)
* DistUpgrade/DistUpgradeCache.py: improve messaging regarding failures to
calculate the upgrade and suggest using ppa-purge if PPAs are an issue.

calculate the upgrade provide information about the log files in
/var/log/dist-upgrade. (LP: #1771387)
* debian/source_ubuntu-release-upgrader.py: Include xorg_fixup.log if it

ca-certificates (LP: #1796940)

New changelog entries:
* DistUpgradeQuirks.py: if ubuntu-desktop or snapd isn't in the package
cache don't try and run the quirk for installing or upgrading snaps.
