[Aptitude-devel] Bug#757940: aptitude: TERM=dumb not respected

Tue Aug 12 15:21:34 UTC 2014

Package: aptitude
Version: 0.6.11-1
Severity: minor

Dumb terminals only support a limited number of control codes.  In
particular they do not have the ability to process ANSI escape
sequences which are commonly used for a number of aptitude's commands
to display progress of steps.

As far as I can gather this is a matter of avoiding some of the
conditionals in the switch statement in src/download_item.cc:77.
The problematic cases are the “transient” states: StatIdle,
StatFetching, and StatDone.

This makes the output of the following command rather ugly:

~ % TERM=dumb aptitude update

The expected output should be what you see in an intelligent terminal:
