Public bug reported: I was upgrading salt-master and salt-minion (installed from their official PPA http://ppa.launchpad.net/saltstack/salt) with muon-updater GUI, but upgrade process stopped on "Waiting for configuration file" status message.
Original bug report with screenshot: https://github.com/saltstack/salt/issues/23663 Apparently, muon-updater did not produce some kind GUI prompt to answer debconf question: $ tail -f /var/log/apt/term.log Configuration file '/etc/salt/master' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? 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. *** master (Y/I/N/O/D/Z) [default=N] ? To reproduce: Manually install older slat-minion, salt-common: https://launchpad.net/~saltstack/+archive/ubuntu/salt2014-7-4/+files/salt-common_2014.7.4%2Bds-1trusty1_all.deb https://launchpad.net/~saltstack/+archive/ubuntu/salt2014-7-4/+files/salt-minion_2014.7.4%2Bds-1trusty1_all.deb Also, manually install their dependencies, but do not upgrade salt itself: $ sudo apt-get -f install dctrl-tools libpgm-5.1-0 libzmq3 python- m2crypto python-msgpack python-yaml python-zmq Then, change /etc/salt/minion line: #master: salt into master: salt Then, open muon-updater, check for available updates and proceed installing latest salt-minion. Installation will not finish.
