[Test Case] You need to create a situation where you'll receive a conffile prompt since the handling of those is broken. 1) On a bionic system modify /etc/update-manager/release-upgrades so that Prompt=normal 2) Test an upgrade from bionic to cosmic or disco i.e. run do-release-upgrade --frontend DistUpgradeViewNonInteractive 3) Observe the upgrade hang on the '/etc/update-manager/release-upgrades' conffifle and the following in /var/log/dist-upgrade/main.log "2019-05-10 21:21:21,313 WARNING got a conffile-prompt from dpkg for file: '/etc/update-manager/release-upgrades' 2019-05-10 21:21:26,319 ERROR error 'a bytes-like object is required, not 'str'' when trying to write to the conffile" With the version of the release-upgrader from -proposed you'll no longer observe the upgrade process hanging. [Regression Potential] The fix is making it so that a byte object is passed to the prompt instead of a string one so there really isn't one, however additional logging which could result in a Traceback if the syntax of that is wrong. [Original Description] I'm trying to do some automated testing that involved upgrading a system from xenial to bionic, so I need it to not ask for user input. Before running do-release-upgrade, the system got a fresh dist-upgrade and reboot. To avoid interactive responses, I'm using: $ sudo do-release-upgrade -d -f DistUpgradeViewNonInteractive Part way through the upgrade, I do get prompted for something though: Preparing to unpack .../apt_1.6.3ubuntu0.1_amd64.deb ...

Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. Comparing the sha1 of apt-compat before the upgrade to another xenial system that has been unmodified, they are the same: In /var/log/dist-upgrade/main.log, I also found this: 2018-10-04 14:20:24,575 WARNING got a conffile-prompt from dpkg for file: '/etc/cron.daily/apt-compat' 2018-10-04 14:20:29,580 ERROR error 'a bytes-like object is required, not 'str'' when trying to write to the conffile To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1796193/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
