How is this possibly a bug in exim4-config? That package does not specify what command dpkg should use in order to page diffs.
Looking at the dpkg source code, it first checks $PAGER and if that's not set falls back to running the "pager" executable. That suggests one of two things:
- you have $PAGER set to "less -Lis" and for some reason don't have less available - your /usr/bin/pager alternative points to something that's not installed on your system.
1) What is $PAGER set to in the environment in which you performed the upgrade? 2) What does /usr/bin/pager point to? (Please chase any symlinks to the ultmate endpoint)
3) How precisely did you invoke dpkg? Regards, Adam
