The bug was present in 1.6.3, but it seems to have been fixed in 1.6.3ubuntu0.1.
If you roll back to 1.6.3, it's easy to reproduce it: $ PAGER= $ apt changelog apt It shows this error message: usage: which [-as] program ... and then goes on to show the changelog for apt. Whether apt called which or not, it was a bug nonetheless. The changelog for apt doesn't mention fixing this, but it has been fixed because it cannot be reproduced on 1.6.3ubuntu0.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782567 Title: apt changelog outputs "usage: which [-as] program ..." if variable PAGER doesn't exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1782567/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
