Package: apt Version: 1.4~rc2 Severity: normal Dear Maintainer,
* What led up to the situation? The problem is present 'apt upgrade'. * What exactly did you do (or not do) that was effective (or ineffective)? When using a dumb terminal (i.e. TERM=dumb) the output of the progress bar when doing 'apt-upgrade' leave a lot of undesired character in the output. In my case the terminal used is shell-mode in emacs. which can launch with M-x shell inside emacs. * What outcome did you expect instead? A clean output. -- Package-specific info: -- (no /etc/apt/preferences present) -- -- (no /etc/apt/preferences.d/* present) -- -- /etc/apt/sources.list -- # # deb cdrom:[Debian GNU/Linux 8.0.0 _Jessie_ - Official Multi-architecture amd64/i386 NETINST #1 20150425-17:05]/ jessie main #deb cdrom:[Debian GNU/Linux 8.0.0 _Jessie_ - Official Multi-architecture amd64/i386 NETINST #1 20150425-17:05]/ jessie main deb http://ftp.fr.debian.org/debian/ stretch main contrib non-free deb-src http://ftp.fr.debian.org/debian/ stretch main contrib non-free deb http://security.debian.org/ stretch/updates main contrib non-free deb-src http://security.debian.org/ stretch/updates main contrib non-free # stretch-updates, previously known as 'volatile' deb http://ftp.fr.debian.org/debian/ stretch-updates main contrib non-free deb-src http://ftp.fr.debian.org/debian/ stretch-updates main contrib non-free -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages apt depends on: ii adduser 3.115 ii debian-archive-keyring 2014.3 ii gpgv 2.1.18-3 ii init-system-helpers 1.47 ii libapt-pkg5.0 1.4~rc2 ii libc6 2.24-9 ii libgcc1 1:6.3.0-6 ii libstdc++6 6.3.0-6 Versions of packages apt recommends: ii gnupg 2.1.18-3 ii gnupg2 2.1.18-3 Versions of packages apt suggests: pn apt-doc <none> ii dpkg-dev 1.18.22 ii powermgmt-base 1.31+nmu1 ii python-apt 1.4.0~beta2 ii synaptic 0.84.1 -- no debconf information
