Package: dpkg Version: 1.19.7 I am pretty sure this is not supposed to happen:
# aptitude upgrade : Setting up smartmontools (7.1-1~bpo10+1) ... Installing new version of config file /etc/default/smartmontools ... Installing new version of config file /etc/init.d/smartmontools ... Configuration file '/etc/smartd.conf' ==> 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. *** smartd.conf (Y/I/N/O/D/Z) [default=N] ? d sh: pager: command not found dpkg: error processing package smartmontools (--configure): conffile difference visualizer subprocess returned error exit status 127 : Regards Harri
